FY16 7 REnigma A Tool to Reverse Engineer Malware that responds with false data In the final stage REnigma performs automated analysis and generates a report summarizing the malware's behavior such as exploitation methods indicators of compromise and decrypted command-and-control communication The analyst can also use an indexed timeline to quickly jump to points of interest captured during recoding and manually examine the behavior in detail Benefits REnigma provides an analyst with a new capability to analyze malicious malware samples to understand their functionality at a level of detail not previously possible Additionally REnigma is designed to integrate standard tools allowing the analyst to retain and leverage existing skills For example a user can replay execution and stop at various points during replay and dump system memory This memory image can be fed into Volatility which is an industry standard tool for extracting key artifacts from raw memory dumps Furthermore REnigma incorporates a framework to create new modules that can extract arbitrary information during replay Advanced analysts can employ REnigma's modules as well as create their own custom modules immediately resorting to manual reverse engineering as anti-analysis techniques become increasingly common potentially saving tens of thousands of dollars per code sample analyzed next Steps JHU APL researchers have used REnigma to examine newly discovered malware found on the JHU APL network We seek operational partners looking for cutting edge malware analysis tools and plan to work closely with the partners to improve REnigma's capabilities We are also seeking additional sponsorship to further develop these capabilities and scale up our deployments Competitive Advantage The key technology behind REnigma is JHU APL's Virtual Machine Record and Replay capability Record and replay research prototypes over the past 20 years were never fully developed were not robust did not have high performance or are not available to others JHU APL developed RnR by modifying the open source Linux kernel and QEMU software systems The RnR capability can record operating systems and applications running at speed with a modest 5% slowdown compared to a virtual machine that is not recorded During replay the precise execution of a malware sample can be recreated with instruction-level precision REnigma's ability to perform in-depth instruction-level analysis without disturbing the code sample reduces the need for expert reverse engineers to load the code in tools like IDA Pro and manually edit it to remove antianalysis checks and force the malicious code to execute REnigma allows security conscious organizations to avoid 8 S T Cyber Security Division Transition to Practice Program Technology Guide -

FY16 PcapDB Optimized Full Network Packet Capture for Fast and Efficient Retrieval Paul Ferrell Shannon Steinfadt pferrell@lanl gov shannon@lanl gov Overview Capturing and analyzing network traffic is key to protecting and detecting intrusions on networks and systems PcapDB is a database system designed from the ground up It optimizes full network packet capture for fast and efficient retrieval Packets are reorganized and indexed by flow before they are ever written to disk PcapDB gives cyber analysts and incident responders fast search and retrieval capabilities while limiting disk access unlike any other open source tool It is a software solution designed for easy deployment on commodity hardware PcapDB allows for large-scale installations at a significantly lower cost than existing commercial solutions Customer Need Cyber security incidents are often discovered hours weeks or even months after they happen On average advanced persistent threat APT actors are inside networks and systems for one year with multi-year durations up to five years of entrenchment reported before being discovered To fully assess the threat and scope of cyber incidents analysts need access to full network packet capture pcap files for as much of the incident time frame as possible Full packet capture gives an analyst a complete picture of network traffic during the time of the incident similar to a black box flight recorder Pcap allows reconstruction of malware transfers downloads command and control messages and exfiltrated data To be effective the captured packets should be easily searchable and have a long a history the largest amount of pcap as possible Response time is also important while adversaries may have months to prepare an attack analysts have comparably little time to create a comprehensive and effective response once detected Full packet captures enable analysts to assess and respond to the current attack and prepare for the next one Our Approach Full packet capture while highly dependent upon the speed at which a system can move packets from a network interface onto disk is not otherwise a very hardware intensive process PcapDB uses the abundance of CPU cycles and memory in modern servers to optimize the captured packets for indexing and storage before they are ever written to disk It organizes the data by the entire transfer flow rather than individual packets The flow-ordered pcap fcap provides data in units the users expect rather than how it happens to come in over the wire The indexing structures and algorithms of PcapDB are designed to take full advantage of this flow ordering and other unique properties of the packet capture problem In doing so we minimize disk interaction thus greatly improving system performance Additionally the indexing techniques consume significantly less disk space than other solutions leaving 99% of the disk for captured packets This allows users to make the most of the disk investment required by packet capture systems S T Cyber Security Division Transition to Practice Program Technology Guide - FY16 11 PcapDB Optimized Full Network Packet Capture for Fast and Efficient Retrieval PcapDB is inherently parallel designed to scale across multiple capture nodes to handle higher capture rates Queries are resolved using a Map-Reduce-like model first distributed amongst the various capture nodes and then combined into the final result on a central search system This allows for distributed capture that is scalable to meet different capture needs and requirements Benefits PcapDB pares down the packet capture features to exactly what cyber analysts and incident responders need to do their job effectively swift searching across the longest logically ordered history achievable The result is a system where users can rapidly investigate intrusions and potential threats from an institution with a greater chance for success PcapDB's optimizations greatly reduce the amount of time needed to retrieve stored packet captures Individual network flows can be retrieved with a single contiguous disk read with little to no reading of unnecessary data Indices can similarly be searched with only a few disk seeks each Since reading from disk is by far the slowest part of data retrieval the elimination of wasteful disk access allows PcapDB to retrieve results almost as quickly as physically possible on modern hardware PcapDB eliminates the need to pay for costly commercial packet capture hardware We provide a guide for building affordable capture systems using commodity hardware The savings can be used to expand the usefulness of the resulting system Rather than purchasing a capture system that can only hold a few days' worth of capture data PcapDB can store weeks or months of capture data on low-cost commodity Serial Attached SCSI SAS disks and just a bunch of disks JBOD enclosures The longest history possible is key when investigating a cyber incident Existing commercial packet capture technologies while capable of high speed capture prioritize increasing their feature sets in order to sell the capture hardware rather than improve their basic packet storage and retrieval functionality These additional features typically result in an index structure that consumes a significant fraction of the available disk space This disk space is better utilized storing captured packets giving a longer history PcapDB can retain over 90% more capture data on disk over some commercial systems with huge indexes and unnecessary software Commercial systems are typically built upon commodity hardware sold at a 10x markup for $200K or more with just a few days of retention PcapDB capture nodes with 150 TB of SAS storage 14 days of capture at 1 Gb s can be built for as little as $20K and only require minor assembly Lowering hardware costs by an order of magnitude allows users to affordably scale their deployments both to capture at higher data rates and to have a longer data retention period Next Steps The core functionality of PcapDB is complete The user interface is rapidly nearing a deployable state for a production environment PcapDB is currently being tested on networks with live data up to 100 Gb s of bandwidth We seek partners to deploy and utilize this technology at their sites Competitive Advantage PcapDB index files are designed specifically around packet data and the write-once read-many nature of captured data to allow for extremely efficient usage of precious storage space 12 S T Cyber Security Division Transition to Practice Program Technology Guide - FY16 REDUCE Collaborative Statistically Guided Exploration of Malware Similarities Juston Moore jmoore01@lanl gov Overview REDUCE is a software toolset enabling cyber security analysts to rapidly discover relationships between malware samples to extract temporal threat intelligence and to develop actionable signatures for known and emerging threats REDUCE performs automated static code analysis and identifies similarities between malware samples in order to support knowledge sharing about related pieces of malware By integrating with wellestablished reverse engineering tools REDUCE speeds up both deep-dive reverse engineering efforts and custom signature generation existing knowledge about a small set of samples in order to rapidly make inferences about the authorship and technical characteristics of new samples Customer Need Large enterprise networks are constantly under attack by a huge number of threat actors Each threat actor commonly deploys many variants of the same malware in order to defeat anti-virus defenses Responding to the constant emergence of new and evolving malware threats cyber defenders require the ability to easily compare new malware with previously seen malware samples and to efficiently develop and deploy custom signatures to guard against targeted attacks Manual analysis of malware yields invaluable information but analyzing many similar malware samples one at a time is very inefficient Cyber security analysts currently lack tools to perform in-depth analyses of more than one or two pieces of malware at once Analyzing similarities between sets of malware rather than characteristics of individual samples allows an analyst to work more efficiently and to easily transfer knowledge from previous analyses on similar pieces of malware Our Approach REDUCE provides a centralized software toolset for automatically performing static analysis on a collection of malware samples Once samples have been uploaded and processed REDUCE uses statistical techniques to identify similar code sections across many malware samples Identified similarities enable an analyst to leverage In addition to providing guidance and insight during an in-depth examination of malware REDUCE also allows an analyst to quickly construct robust signatures for known and emerging threats The REDUCE signature generation process is guided by information theoretic principles which help to identify features that are distinctive to the set of interest while eliminating features common across software samples in general Signatures are generated in the open-source YARA format YARA signatures can be deployed on a wide variety of security appliances and easily translated into other formats to be deployed across an enterprise Benefits REDUCE is a practical toolset developed by analysts in an operational incident response environment REDUCE helps analysts to focus on specific code patterns and threat actors rather than peculiarities of individual malware samples REDUCE enables a reverse engineering workflow and complements tools commonly used by security analysts The REDUCE user interface gives analysts a big-picture view over collections of malware while also facilitating S T Cyber Security Division Transition to Practice Program Technology Guide -

FY16 SilentAlarm Detecting Abnormal Network Traffic Joel Doehle joel doehle@pnnl gov Overview SilentAlarm is an inference-based technology for detecting abnormal network traffic that depends on dynamic network behavior knowledge rather than static signatures and thresholds It characterizes network behavior as likely malicious and enables the detection of zero-day attacks and polymorphic malware without needing prior knowledge of their specific characteristics Customer Need To enact effective cyber security organizations need to be able to detect unknown malware targeting unidentified vulnerabilities Many existing security solutions are signature-based utilizing a detailed description of a given malware's characteristics to detect its presence on their systems and networks These technologies require specific foreknowledge of a malware's form or function As a result they are incapable of detecting unknown malware or attacks exploiting as-yet undeclared vulnerabilities This leaves organizations vulnerable to adversaries using tactics such as zero-day attacks and polymorphic malware Better solutions are needed to enable organizations to identify and address these and other types of attacks without the detailed foreknowledge required to develop a signature Figure 1 SilentAlarm Inference Network Architecture Network events are fed into SilentAlarm through various types of sensors e g network anomaly protocol anomaly that are already in place on a network The traffic collected at these sensors is ingested by knowledge nodes that are associated with a particular network behavior e g failed or successful SMTP failed intranet connection These knowledge nodes characterize the ingested traffic based on the metrics of prior network behavior SilentAlarm utilizes dynamic behavioral analysis to detect abnormal network traffic resulting from malware and malicious intrusions and takes action to address the malicious software behind them These characterizations are pushed up to hypothesis nodes that construct hypotheses regarding the likely malicious nature of the observed traffic Each hypothesis node conducts reasoning about one type of malicious action e g port scanning In order to do so it subscribes to the characterizations of one or more knowledge nodes and assigns weighting values to the results of each Collectively these characterizations enable the hypothesis node to deduce whether the observed traffic is indicative of a particular malicious action SilentAlarm provides this capability by employing a Bayesian inference model that analyzes and correlates network traffic using dynamic network behavior knowledge in order to construct hypotheses regarding likely malicious activity When such a determination is made and the associated confidence value is greater than or equal to an alert value a security action can be performed e g sending an alert to a system administrator or disabling or restricting network access to a particular resource Our Approach S T Cyber Security Division Transition to Practice Program Technology Guide - FY16 21 SilentAlarm Detecting Abnormal Network Traffic Network behavior data is continuously collected through the deployed sensors This data - along with administrator input and feedback into the knowledge and hypothesis nodes regarding characterization and confidence values - enables SilentAlarm to learn and refine its understanding regarding abnormal network behavior Next Steps Benefits We would like to partner with a sponsor who is interested in renewing this technology and pursuing potential commercial opportunities for it SilentAlarm is able to characterize network traffic as likely malicious based on knowledge of prior network behavior and an inferential understanding of what constitutes abnormal network behavior In this way SilentAlarm is not wholly dependent on static thresholds and signatures as many traditional malware detection methodologies are As a result SilentAlarm can detect previously unknown malware including polymorphic malware and attacks against zero-day vulnerabilities based on its behavior in a network Several years have passed since SilentAlarm's initial development and operational use The technology needs to be updated to reflect current network behaviors and to develop sensors for today's network event logging technology 1 Goranson Craig A and John R Burnette Methods and systems for detecting abnormal digital traffic U S Patent 7 908 357 issued March 15 2011 This technology is device and network agnostic It can be adapted to integrate with presently deployed sensors on an enterprise environment It is also highly scalable across various network sizes SilentAlarm has been proven effective in an active enterprise environment serving as an integral component of the security of the PNNL network for several years Upon initial deployment SilentAlarm correctly identified 200 machines that were infected with zero-day type malware out of a network of 10 000 computers In continued operation SilentAlarm identified zero-day type malware on the network within three minutes of machine compromise Competitive Advantage SilentAlarm is highly adaptable and extensible across varying network environments with myriad sensors It offers proven behavioral based anomaly detection that provides an enhanced complement to signature-based solutions Additionally we possess a patent1 on the technology that prevents others from developing the same type of product 22 S T Cyber Security Division Transition to Practice Program Technology Guide -

FY16 Situ Discovering and Explaining Suspicious Behavior John Goodall Joel Reed jgoodall@ornl gov reedjw@ornl gov Overview Situ is a scalable real-time platform for discovering and explaining suspicious behavior that current technologies cannot detect Customer Need Despite the best efforts of cybersecurity analysts networked computing assets are regularly compromised resulting in the loss of intellectual property the disclosure of state secrets and financial damages in the billions A 2014 report from the Center for Strategic and International Studies estimated the global cost of cyber crime at $400 billion annually There has also been a rise of sophisticated attack groups that continually develop novel methods of penetrating networks that current technologies are typically unable to detect Signature-based security systems are effective at detecting known attacks but are unable to detect novel or sophisticated attacks Indeed automated security systems will never be capable of detecting all malicious activity network operators need tools to help identify suspicious behavior that bypasses automated security systems In the deluge of data in today's networks operators cannot be expected to discover suspicious activity without better tools Further operators need to understand what makes an event suspicious to determine the importance and impact of the event Highlighting such suspicious behavior helps operators focus their limited time on the most suspicious events within vast amounts of data Our Approach Situ combines anomaly detection and data visualization to provide a distributed streaming platform for discovery and explanation of suspicious behavior to enhance situation awareness Our novel approach to anomaly detection is based on unsupervised probabilistic modeling Key to our approach is modeling events in different contexts or at multiple scales each event is modeled and scored by multiple anomaly detectors to identify different kinds of anomalous behavior For example a context may group events by day of the week or hour of the day to build a model of temporal behavior for each computing asset The anomaly detectors update the behavior models online as new data is streamed into the system The detectors score each event for each context based on the likelihood of new events occurring given the probability model of prior behavior Scoring the anomalousness of events for multiple contexts provides analysts with an understanding of why an event is anomalous By examining these contexts operators can understand how different event features contribute to the overall anomaly score The architecture of Situ is designed to scale to very high data rates on commodity hardware--hundreds of thousands of events per second The system stores data on compute nodes for very fast updates and queries Scored events are published to a data store for archival review and historical analysis Scored events are also pushed immediately to a web-based visualization to allow operators to monitor the most suspicious events in realtime Benefits Situ helps network operators discover and understand suspicious events that would otherwise go undetected It reduces the huge volumes of raw network data to a smaller manageable number of events that should be examined by human domain experts By highlighting suspicious activity operators can find novel attacks but can also be made aware of insider threats policy violations misconfigurations and new kinds of behavior that may require some investigation Through the application of multiple contexts Situ can look for a wide range of activity Different contexts perform better for S T Cyber Security Division Transition to Practice Program Technology Guide - FY16 27 Situ Discovering and Explaining Suspicious Behavior figure 1 Situ's streaming user interface shows the most critical events different kinds of attacks Multiple contexts can also help explain why an event is suspicious since the varying scores will point operators at certain kinds of behaviors Situ is generally applicable to other domains such as intelligence analysis and cyber-physical infrastructure protection that require real-time behavioral monitoring Competitive Advantage Situ's probabilistic approach to anomaly detection has several advantages over other methods Signature-based discovery systems can only identify known patterns of malicious behavior Situ complements such systems by highlighting suspicious behavior that existing systems cannot detect Machine learning offers a more robust approach but typically requires labeled training data which is rarely available and usually out of date Situ requires no labeled training data making it easier to deploy in operational environments Machine learning approaches typically train periodically offline Situ trains online so that data models are always up to date Other approaches to anomaly detection in cybersecurity commonly help identify atypical events or time windows where an anomaly occurred Situ goes further and helps operators understand why something is anomalous through the scoring and reporting on multiple contexts 28 Many approaches to anomaly detection and attack discovery operate in batch mode e g map-reduce jobs in a Hadoop store which ignores the reality of the speed of cyber attacks By the time detection takes place the attacker may have come and gone Situ operates on real-time streaming data minimizing the time from the observation of an event by a sensor to the reporting of the event to the operator Finally other approaches to attack and anomaly detection typically have large numbers of false positives which leads operators to mistrust or ignore alerts Situ has an adjustable false positive rate that allows an operator to define the acceptable percentage of false positives to set the threshold for discriminating anomalous from normal behavior Our visualization approach is unique in that it focuses on streaming data reducing the time it takes to be notified of important events Next Steps We are currently improving the user interface by creating multiple visualizations that allow analysts to seamlessly move back and forth between a view of the streaming data and a visual query interface to search through archival data We are looking for potential pilot and test sites as well as commercialization and transition partners to put Situ into the hands of the operators who need it S T Cyber Security Division Transition to Practice Program Technology Guide -

FY16 AMICO Accurate Behavior-Based Detection of Malware Downloads Roberto Perdisci Kang Li perdisci@cs uga edu kangli@cs uga edu Overview Our Approach AMICO is a novel open source software system for accurate behavior-based detection of malware downloads in live web traffic Once deployed at the edge of a network AMICO automatically learns how to distinguish between malware and benign software downloads by observing the download behavior of the network users themselves After the initial learning phase AMICO is able to automatically detect new including zero-day malware downloads in the monitored web traffic and can alert network security personnel with detailed incident reports about the detected events AMICO's behavior-based approach to detecting malware downloads is based on the following main intuition to evade existing defenses malware distribution operations must be agile Customer Need Sensitive computer networks are under constant attack Cyber criminals can gain almost unrestricted access to a network by leveraging malicious websites to force users to download and run malicious software This allows the attackers to implant malware into the network and to create a backdoor that can lead to costly data breaches and loss of intellectual property For example to avoid antivirus detection malware developers make heavy use of code obfuscation and polymorphism to frequently change their malware files On the other hand benign executable files usually change only when a new version is released Furthermore to evade URL blacklists malicious websites that distribute malware need to frequently relocate for example by changing their domain name and IP addresses On the other hand benign executable files are typically hosted at professionally operated service providers with a stable domain name and network infrastructure Most networks rely on traditional antivirus software to protect themselves from malware downloads Unfortunately security researchers have repeatedly demonstrated that anti-virus defenses are only partially effective and may miss more than 65% of the latest malware threats Other existing malware download defenses make extensive use of URL blacklists to prevent users from accessing known malware distribution sites However by nature these blacklists lag behind the new threats and fail to detect a significant number of new malware Therefore there exists an urgent need for novel malware download detection systems that can better protect a network's perimeter by accurately detecting new neverbefore-seen malware files and the related malware distribution sites To leverage these intuitions AMICO combines advanced network traffic monitoring with artificial intelligence and data mining methods AMICO passively monitors all web traffic at the edge of a network Every time a user downloads an executable file the system performs an on-the-fly reconstruction of the download from the network traffic and stores the file into a download history database along with provenance information regarding who i e what machines downloaded the file and where i e what website the download came from S T Cyber Security Division Transition to Practice Program Technology Guide - FY16 35 AMICO Accurate Behavior-Based Detection of Malware Downloads During an initial training period some of these download events are first labeled as either benign or malware using the partial ground truth provided by existing antivirus tools Given these labeled events and statistics about the download behavior of the network users collected during the training phase AMICO automatically learns a web traffic model that can be used to accurately classify future malicious file downloads based simply on their provenance characteristics Benefits AMICO is able to efficiently reconstruct and accurately classify new malware file downloads by passively monitoring web traffic from the network edge It explicitly leverages the fact that modern malware distribution operations are highly agile and turns the attackers' strategy into an advantage for the defenders Next Steps AMICO has been tested via pilot deployment in a large academic network serving tens of thousands of users where it was able to detect more than 95% of all new malware file downloads and about 80% of malware files missed by existing defenses Pilot testing in other operational environments would provide an important opportunity to improve performance usability and to compare AMICO to other existing defense solutions In addition we are seeking partners and sponsors who are interested in fostering the widespread adoption of AMICO AMICO automatically learns how to distinguish between malware and benign software downloads by observing the download behavior of the network users providing a defense that can self-adapt to the deployment network and further improve detection accuracy Competitive Advantage AMICO provides a fully open source and easy to deploy solution for detecting malware downloads in live web traffic AMICO's download classifier does not rely on signatures and therefore is not affected by malware code polymorphism and obfuscation Instead AMICO leverages malware polymorphism as a feature to enable a more accurate detection of malware download events Furthermore AMICO does not rely on URL or domain name blacklisting and does not need to run malware files in a sandboxed environment Unlike existing defenses AMICO is able to detect neverbefore-seen malware download events by leveraging their provenance characteristics and by automatically learning from the download behavior of the network users themselves Therefore AMICO provides an effective complement to current antivirus and malware defense solutions 36 Funded through the National Science Foundation's NSF Division of Advanced Cyberinfrastructure ACI Cybersecurity Program S T Cyber Security Division Transition to Practice Program Technology Guide - FY16 ZeroPoint Advanced Weaponized Document Detection and Analytics Kevin Z Snow Fabian Monrose kzsnow@cs unc edu fabian@cs unc edu Overview The ZeroPoint Platform provides highly effective highthroughput next-generation detection and diagnostics of exploit payloads embedded in documents distributed via email and the web content used in so-called drive-by downloads and attacks on network servers Customer Need Today the widespread proliferation of document-based exploits distributed via massive email and web-based attack campaigns is an all too familiar strategy Attackers use this tactic to kickoff full-scale data breaches by weaponizing documents and web content to gain total access to the recipient's computer In 2012 these data breaches cost an average of $5 5 million per incident a figure on the rise as organizations increase their online presence and threats become more sophisticated In August 2014 for example several large financial institutions lost gigabytes of data to cyber criminals targeting the financial sector Sadly contemporary defenses have failed to keep pace with the relentless onslaught of evasive techniques that are readily available from off-the-shelf attack toolkits In light of this everpresent threat there is a need to empower organizations to allow end-users to safely use email and browse the web Our Approach The ZeroPoint Platform is a network appliance that analyzes documents email web content and server interactions collected from network border traffic and operator-submitted content Potentially hazardous documents or web content are launched or replayed in their target application to dynamically unpack embedded exploit payloads and then application memory is inspected to discover those payloads The key to the ZeroPoint approach is a patented execution of data technology that uses an advanced micro-OS built into the analysis engine to enable fast accurate inspection of data or memory to identify exploit payloads This core technology takes advantage of hardware virtualization to inspect all data by directly executing it to discover what lurks within without relying on any form of software emulation There is no need to guess whether a resource is malicious based on trivially obfuscated file content post-infection behavior that can easily be disguised or out-of-date signatures ZeroPoint hones in on the small portion of an attack the adversary cannot omit or quickly adapt - the exploit payload - by leveraging the fact that exploits operate under practical constraints that bound their operations in ways that make them detectable Benefits The ZeroPoint Platform enables users to safely use email and browse the web with the confidence that attacks are promptly discovered at the first stage before data is lost The platform transparently provides complete networkwide protection with no downtime to deploy inspects each document or web page in about one second and produces virtually no false alarms Our core technology has already been validated on the University of North Carolina Chapel Hill campus 29 000 students with 5 Gbps average load and large-scale empirical analysis spanning 10 000 weaponized documents ZeroPoint's diagnostic functionality also enables operators to preemptively block connections to malicious domains found in the inspected content Competitive Advantage Contemporary approaches for detecting attacks have relied on antivirus signatures of previously observed attacks Unfortunately the delay between the first use of an attack and the deployment of its signature is too often measured in weeks and months Meanwhile the attackers continually compromise users Moreover signatures are widely known to produce many false alarms A myriad of recent solutions and products-most based on sandboxing technology-claim to avoid the pitfalls of signatures and protect against zero-day attacks However these containment mitigations are complex and costly to deploy and manage on endpoints Instead ZeroPoint provides transparent and network-centric detection Other detection solutions leverage sandboxes for S T Cyber Security Division Transition to Practice Program Technology Guide - FY16 37 ZeroPoint Advanced Weaponized Document Detection and Analytics figure 1 - the deployment scales-up with multiple analysis engines in a cloud-ready model or rolls all components into one rackmounted server in stand-alone deployments capable of tens of thousands of inspections a day behavioral analysis Unfortunately that behavior is easily camouflaged with benign activity only revealing itself after an extended period of time or is limited to the analysis of executable files Rather than fruitlessly attempting to keep up with the fast pace of new attack signatures and easily disguised behaviors our technology turns the tide by moving away from this status quo and avoiding signatures and observable post-infection behavior altogether Our underlying technology has not required any signature behavior or heuristics updates over several years and yet we continue to find weaponized documents where other solutions fail - a testament to the solid foundation on which ZeroPoint is built In short ZeroPoint takes a unique approach that is faster more accurate and more informative than other solutions Next Steps Two U S Patents that protect the core technology are pending We seek commercialization of our technology through partnering or licensing with a major vendor of network security products We also seek pilot deployments with large organizations for our stand-alone or cloud-ready prototypes Funded through the National Science Foundation's NSF Division of Advanced Cyberinfrastructure ACI Cybersecurity Program 38 S T Cyber Security Division Transition to Practice Program Technology Guide -

FY16 41 CodeDNA Scalable High-Speed High-Volume Shareable Malware Detection Competitive Advantage Next Steps The lack of an automated repeatable robust alternative to signature-based malware detection for fast clustering of malware into families has stymied attribution and crippled attempts by defenders to collaborate and join forces The prototype CodeDNA is ready to be piloted and tested within a malware processing environment followed by a move to enterprise-level testing We are currently running CodeDNA as part of APL's perimeter defense and are seeing interesting results We envision embedding CodeDNA into an existing malware processing system that would provide unpacking decryption and de-obfuscation Rules for processing CodeDNA matches would then lead to automatic blocking of known malware and its variants while also updating records of attempted attacks We believe that CodeDNA can be expanded beyond our currently supported file formats x86 Mono Net PDF and JavaScript to include other executable and digital media formats We are searching for a transition partner to pilot CodeDNA in an enterprise environment We are also seeking a government sponsor to fund continued research focused on mining the malware relationship data provided by CodeDNA to investigate predictive analyses of malware development These analytical methods could expand the fast recognition of never-before-seen variants that is vital to anticipating malware developers' next moves CodeDNA effectively identifies clusters of related malware in very large datasets and reports the degree of similarity For example CodeDNA recently found 1 8 million clusters i e groups of related malware binaries in a sample of 3 6 million binaries with unique checksum identifiers provided by Offensive Computing offensivecomputing net thus demonstrating the ability to match 90 000 malware samples per hour on inexpensive cloud nodes running Hadoop We believe our algorithm will scale linearly in time and cost for handling higher volumes of malware ingest CodeDNA recognized 1 000 of 4 800 malware samples provided by the Georgia Institute of Technology as malware variants that were not identified by 10 leading anti-virus vendors demonstrating correlation of variants not achievable with current techniques In a recent cyber espionage data set 90% of 1000 binaries proved to be strongly related to one another when evaluated with CodeDNA Another sample of 32 000 malware binaries matched against Windows 7 using CodeDNA showed that malware authors use Windows 7 code but did not report false positives In addition the recently added fingerprinting for PDF format files demonstrates that adversaries re-use their PDF exploits as well as their executable binary exploits 42 S T Cyber Security Division Transition to Practice Program Technology Guide -

FY16 49 Digital Ants Dynamic Resilient Infrastructure Protection strength of the swarm and the severity of the reported data before informing human operators of a potential issue A unique strength of the Digital Ants approach is the framework's ability to identify previously unknown cybersecurity concerns via swarm intelligence Individually each sensor provides only a partial indication of anomalous conditions However a sensor swarm will form where there are numerous unusual issues Swarms focus operators on large complex anomalies rather than individual issue alerts Digital Ants' sensors require no centralized control enabling the framework to scale to very large infrastructures Furthermore because any combination of sensors can trigger a swarm unknown malware can be detected and the sensor composition of the swarm can be used to help classify the malware's signature Benefits The Digital Ants framework is a lightweight cyber defense designed to protect very large infrastructures even millions of devices Digital Ants minimizes network communication by performing the analysis at the edge The framework does not overburden edge CPUs because sensors do not run all the time on all the nodes Thus infrastructure owners avoid the cost of high-end centralized storage and analysis servers Automatic learning reduces the human cost of configuration and supervision As the sentinels observe their systems they will silently and efficiently learn to differentiate between normal behaviors and previously unknown or potentially serious situations Digital Ants handles the low-level anomalies automatically giving human operators more time to focus on operations and security trends Competitive Advantage Digital Ants' lightweight framework enables sensor deployment on devices with modest computational and networking resources Current host-based intrusion detection and intrusion prevention systems consume significant processing power and memory and often require constant connection to external cloud providers Unlike antivirus Digital Ants is always learning so operators do not need to constantly update sensors or malware signatures Eventually our goal is to replace heavyweight antivirus and other host-based agents that consume too many host resources with the flexible lightweight framework provided by Digital Ants Next Steps The Digital Ants Framework has been extensively tested in laboratory environments and on workstation-class machines Our current implementation can be adapted to a number of potential applications Going forward this new cybersecurity paradigm must be field-tested and integrated into existing tools such as Security Information and Event Management SIEM products We are seeking integrators interested in harnessing the power of swarm intelligence to create new resilient protection products We also seek partners who will integrate Digital Ants technology into existing domain-specific products that protect infrastructure and IT networks Finally we seek research sponsors to help us continue to tune and adapt this revolutionary new approach to cybersecurity Digital Ants' simple nature-inspired design means there is no single point of failure making the system naturally resilient to attack Even if many sensors fail our approach ensures each node is routinely visited Although adversaries may be aware of the Digital Ants they cannot predict the sensor movements providing yet another level of resilience to attacks 50 S T Cyber Security Division Transition to Practice Program Technology Guide - FY16 PACRAT The Blended Physical and Cyber Risk Analysis Tool Doug MacDonald douglas macdonald@pnnl gov Overview How secure are your assets and infrastructure Without the right tools to properly assess the vulnerabilities of your most important assets how can you answer that question The Physical And Cyber Risk Analysis Tool PACRAT is a vulnerability and risk analysis software package that blends the methodology and assessment processes used in the physical and cybersecurity domains This blended approach provides an accurate and comprehensive assessment of your overall security strategy taking into account system level interactions and interdependencies Customer Need Every industry market sector or business has valuable assets they need to protect This could be a product proprietary process intellectual property national security asset or critical infrastructure element Most organizations use a combination of physical protection and cybersecurity measures in their overall protection strategy to thwart attackers from attacking assets in each domain The cyber and physical domains must be analyzed together to thoroughly understand how each can affect the other This holistic approach is critical to determining the resources needed to properly protect each asset The approach and methodology used in these types of assessments ultimately determines the accuracy of the results and directly affects the final risk determination Being wrong can have catastrophic consequences Our Approach PACRAT uses a blended approach developed by an integrated team of physical protection specialists and cybersecurity experts with decades of experience in realworld boots-on-the-ground assessments These experts were cross-trained in the process and methodology each domain currently uses PNNL combined and modified these approaches to provide a comprehensive modeling and simulation capability that can evaluate every avenue of approach using both electronic and physical pathways PACRAT builds upon the industry standard Adversarial Timeline Analysis System and incorporates usability features of many of the most widely used analysis tools but adds functionalities like capturing system level interactions and interdependencies and a backtracking capability These elements are critical to properly assessing the true risk to an asset operation or facility with modern integrated security systems PACRAT has been provisioned for a Value-Added Module to assist in prioritizing investment upgrades This automated process will recommend improvements to the cyber-physical systems based on increased performance parameters selected by the analyst The result is an automated what if analysis Benefits PACRAT's ability to blend the physical and cyber domains into a single vulnerability and risk assessment capability provides a more accurate and comprehensive analysis than can be achieved by looking at these domains independently Many organizations consider the cost of performing a comprehensive physical or cybersecurity assessment ranging from $200 000 to $300 000 for a medium-sized facility or campus to be frivolous with no immediate benefit This expenditure can be difficult to justify when risk consequences are not immediately realized However the cost of not performing assessments or even worse not properly performing them can have grave consequences The Great Blackout of 2003 in the Northeast is an example of underestimating the consequence of failure It resulted in 11 deaths and cost the United States economy an estimated $10 billion Similar results may be possible if critical infrastructure elements are not properly protected against a coordinated cyber-physical attack S T Cyber Security Division Transition to Practice Program Technology Guide - FY16 51 PACRAT The Blended Physical and Cyber Risk Analysis Tool The Stuxnet worm which can be classified as a physically enabled cyber attack wreaked havoc on the uranium enrichment programs in Iran setting the program back several years and forcing the replacement of thousands of extremely expensive centrifuges Compromised protection systems in the banking industry can deny customers vital access to company websites and delay financial transactions One report estimated the cost to the financial services industry to be $32 000 for every minute of downtime New terrorist organizations have vowed to attack the U S by going after critical elements of our way of life Next Steps Two prototype PACRAT assessments have been performed to date The software tool and subject matter expertise is ready to be taken to the next step This could be tailoring it to a specific industry or entity to perform detailed analysis in a strategic area or licensing the technology to be used internally or repurposed for other industries In either case PACRAT is well poised to make sure adequate protection is in place to protect your most valuable assets The cost of not adequately protecting vital assets could be astronomical in terms of lost revenue rebuilding and reconstruction costs environmental restoration damage to a company's reputation even loss of life Competitive Advantage PACRAT blends the physical and cyber domains and allows for backtracking attack pathways no other assessment techniques or tools can do this Currently used vulnerability analysis and risk assessment software packages were developed decades ago and have not kept up with the advancements in technology and the increased system level interactions introduced through automation and today's integrated security systems Additionally practitioners in the cybersecurity and physical protection domains have fundamental differences in how they apply their craft Our subject matter experts have been cross trained to understand the intricacies of each process and methodology and have been able to articulate that in the PACRAT tool 52 S T Cyber Security Division Transition to Practice Program Technology Guide - FY16 SerialTap Enabling Complete Situational Awareness in Control Systems Thomas W Edgar Eric Choi thomas edgar@pnnl gov eric choi@pnnl gov Overview The SerialTap is a low cost embedded device for passively tapping serial line communication and transmitting it over an Ethernet network for comprehensive control system situational awareness Customer Need Industrial control systems ICS and IT networks are converging Historically due to physical separation ICS has had limited exposure to the vast number of Internet cybersecurity threats and vulnerabilities but with the merger they now become a problem ICS now require cybersecurity solutions to defend against these threats Large portions of ICS are still operated with legacy serial communications which have largely been ignored by the cybersecurity community This has led to one of the biggest challenges for control system operators retrofitting cybersecurity solutions to legacy systems IT cyber solutions focus on routable networks and are unable to work with legacy serial communications which prevents ICS owners from monitoring their entire infrastructure As demonstrated by new malicious attacks like StuxNet operators cannot trust the self-reported behaviors of field devices The ability to monitor traffic in these legacy communication environments is necessary to provide complete situational awareness of ICS security state Our Approach Legacy communication in ICS is often RS-232 485 serial communication The SerialTap is a small embedded device that is placed passively in-line on the legacy links between process control devices It collects the data sent between the devices determines message boundaries and transmits those messages via a secure UDP packet Figure 1 SerialTap Prototype equipment in the communication path increases the failure risk The SerialTap is designed as a passive tap to remove the risk of SerialTap failure to the process control system Loss of power or a processor failure will not impact process control communication The SerialTap is designed to encapsulate data and transmit it to a centralized location to leverage current enterprise analysis solutions such as cybersecurity incident and event management systems Serial communication is collected by the SerialTap processed to determine message framing and transmitted via secured UDP to a user configurable IP address Centralizing analysis enables detection of system-wide anomalous patterns Benefits The SerialTap provides data monitoring capabilities to enable complete situational awareness in process control systems The SerialTap is a cost effective non-intrusive add-on to monitor and verify the activity in legacy serial communications systems providing the following benefits The SerialTap is designed specifically to fail without affecting the communications between the process o Passive failure to reduce additional risk to ICS control equipment fail-safe The cost of fixing a communication failure can be very high and additional o Integrates easily with common IT enterprise security solutions o Inexpensive design for system wide coverage S T Cyber Security Division Transition to Practice Program Technology Guide - FY16 53 SerialTap Enabling Complete Situational Awareness in Control Systems Next Steps The SerialTap prototypes have been developed and tested in laboratory environments We would like to partner with an industry asset owner to pilot SerialTap in an operational environment and to develop and demonstrate integration with an enterprise situational awareness tool Furthermore it is not within our scope or capability to manufacture this technology We therefore are looking for a manufacturing partner to license this technology to provide its benefits to industry Figure 2 SerialTap Transmitted Data Monitored in Wireshark Competitive Advantage There are no known direct competitors to the SerialTap at this time There are embedded devices available today that perform protocol translation such as serial to IP but none of them perform passive tapping There are two categories of products that compete in the application domains that are attempting to achieve similar end results to the SerialTap however these solutions fall short in two categories The first category is designed for troubleshooting applications and requires physically connecting a computer to an adapter located in the field site This prevents remote collection and analytics across the control system The second category is designed to be active bump-in-the-wire solutions similar to IT firewalls or application proxies While these enable active protection such as blocking known malicious traffic the most common attacks leverage legitimate commands In addition it increases per unit cost and risk due to potential communication failure The SerialTap is a cost effective method to centralize legacy communication for analysis to detect anomalous behavior in the context of the entire system and not just a single device 54 S T Cyber Security Division Transition to Practice Program Technology Guide - FY16 SecuritySeal Critical Protection for Your Supply Chain Todd Bauer tmbaue@sandia gov Robert Brocato Jason Hamlet Brian Wroblewski Overview SecuritySeal is a combined hardware and software solution that enables cryptographically secure authentication of a seal and any object it is affixed to providing anti-counterfeiting protection tamper detection and supply chain risk management for high value assets SecuritySeal is remotely readable and the level of security is scalable to the application Customer Need Global trade in counterfeit goods will top $1 7 trillion per year by 2015 Counterfeit products pose health safety and security risks and create performance deficiencies that have widespread negative consequences Microelectronics pharmaceuticals and chemicals are common targets for counterfeit traders Counterfeit goods hit the manufacturing and retail industries causing loss of reputation legal exposure and loss of sales Legitimate manufacturers investment in R D materials and human capital are diminished by counterfeits that capitalize on a brand's reputation without making the same investments Our Approach SecuritySeal leverages Physical Unclonable Functions PUFs to create physical seals that can be used to verify that a system is authentic PUFs are derived from the inherently random physical characteristics of the system from which they are sourced which makes their outputs physically and computationally impossible to predict or reproduce The PUF output is used as a fingerprint to authenticate a system SecuritySeal implants PUFs in both an integrated circuit IC that is responsible for data processing and in a tamper-detecting seal that is applied with adhesives to the object to be protected The IC PUF is based on well-characterized circuit designs and the seal PUF is based on screen-printed resistors on a flexible film The screen-printed resistors have unique values that depend on the characteristics of the surface to which the seal is adhesively attached We simultaneously measure the PUFs from the seal and from the IC and combine them to create a system-level signature that is unique to any particular IC-seal combination To mitigate man-in-the-middle and playback attacks that can exploit authentication using raw PUF signatures we use a cryptographic challenge-response protocol using public private key pairs seeded from the PUF signature For authentication the verifier and SecuritySeal exchange an encrypted symmetric key using Diffie-Hellman key exchange After this process the verifier and SecuritySeal are in possession of a shared key The verifier then chooses a random value encrypts it with this key and challenges SecuritySeal with this encrypted value Only the original unmodified SecuritySeal will be able to generate the key needed to correctly decrypt the challenge If SecuritySeal returns the correct result to the verifier then the verifier is assured that the correct SecuritySeal is in place and that the item it protects has not been tampered with After authentication the keys and PUF measurements are erased Benefits SecuritySeal enables cryptographically secure authentication of physical seals It is widely applicable in scenarios ranging from safeguarding nuclear material to warranty fraud prevention SecuritySeal can help combat counterfeiting of high-value consumer goods and can satisfy ePedigree Track and Trace requirements for the pharmaceutical industry The security level can be tailored to the application through selection of cryptography algorithms bit generation requirements and communication protocols SecuritySeal can be configured for hard-wired or wireless interrogation Each instance of SecuritySeal is unique and cannot be replicated Unlike most cryptographic systems SecuritySeal generates secret keys as they are needed rather than storing them making the system less vulnerable to attack Leveraging its PUF values SecuritySeal can provide on-board encrypted memory to store application specific data like product lot information Because the key used to protect this memory is generated from the unique PUF values the key does not need to be stored in memory in the SecuritySeal S T Cyber Security Division Transition to Practice Program Technology Guide - FY16 55 SecuritySeal Critical Protection for Your Supply Chain The PUF-based authentication employed by SecuritySeal can be used independently of the seal to permit authentication of integrated circuits ICs This has anti-counterfeiting value to manufacturers and users of ICs This authentication capability has national security implications as it permits authentication of ICs in deployed systems which allows detection and deterrence of modification or substitution to critical systems Competitive Advantage Existing solutions fall short in either of two critical areas 1 seals that are bound to the object that they protect are easy to counterfeit or 2 seals that are difficult to counterfeit are not robustly bound to the system they protect SecuritySeal effectively and efficiently overcomes both vulnerabilities SecuritySeal's unclonability and highly adaptable security level render it valuable in a wide range of applications that require the verification of the integrity of a seal from protecting nuclear material to detecting warranty fraud The SecuritySeal technology is protected by US patent number 8 516 269 56 Next Steps Currently SecuritySeal has successfully completed prototype demonstrations It is ready to be piloted and tested within operational environments to secure high value assets We are actively seeking a partner to bring SecuritySeal to market S T Cyber Security Division Transition to Practice Program Technology Guide -
