  8. 8. Key capabilities of the agent core• Acts independently on/off network• Has it’s own scheduler and local policy cache• Agent can be installed as persistent or self-dissolving after x number of days• There is a run time version of the agent that allows full capability without the need to actually install the agent. (this mode does not allow for persistent/ scheduled functions)• Has protected storage area securely store payload until it can communicate back to site server.
  9. 9. The agent is made up of the following modules• Core: Responsible for managing communication, policy / job execution, and defensive measures, delivering payload, and updating itself• NetFS: Provides the filtering, searching, collection, and preservation capabilities (same technology in agent is what supports network share capability• Cerberus: The ability to identify malware (with no prior knowledge) based of search/filter criteria on running system or network shares across the enterprise. For example a job could be defined to Stage 1 Cerberus score all exe on a given set of systems. Any files that have a high threat score will be automatically sent to the Stage 2 Cerberus analysis. There are options to choose whether the files are preserved or just the metadata.• Volatile: Now users can setup jobs to scan the enterprise and capture volatile data and interact with the data in review. The volatile data includes pre-built facets and the ability to view details for all of the volatile data payload. Volatile data includes Processes, Network Sockets, Dll’s, Handles, Drivers, Services, Network Devices, registry, and users• RAM: Now users can setup jobs to scan the network and analyze RAM along with Volatile or just RAM analysis and interact with the data in review. The volatile data includes pre-built facets and the ability to view details for all of the RAM analysis. RAM analysis includes Processes, Network Sockets, Dll’s, Handles, Drivers, Services, Network, Devices, Processors, and registry.• RMM (removable media module): Enables the targeted monitoring of files coming from and going to removable media (USB/Firewire/CD/DVD). With job options to just record metadata or metadata and payload for documents based off of user defined extensions. Results can be viewed, filtered and searched on in the new review interface with the support of pre-made filter facets to quickly identify documents/files coming from or going to removable media.• SilentRunner : Advanced host based packet capture with robust filtering capabilities• Remediation: Allows for the killing of processes and wiping of files
  10. 10. CIRT – SilentRunner Agent ModuleKey Capabilities Define operating parameters for the agent collector: o on/off o filter based off of these IP address o filter based off of these ports or protocols or application o filter based off of these IP address <to-from> these ports/protocols o define how much data can be collected o define if it stops collecting once it hits max collection o Define if it just has an open rolling buffer. These settings would be applied as a policy/operating parameters o Specify beginning and end for application of the policy o Adhere to a schedule The Pcap payload would be securely stored on the agent Agent will store and forward for ingestion into centralized SilentRunner System for integrated and correlated analysis
  11. 11. Intro to Cerberus• CIRT is the first step towards automated reverse engineering so you can triage a binary before sending it for further analysis• We tally all of the attributes we think are “interesting” into a score that you can sort by• For each binary, you can then drill down into that score to see the attributes that we found that were similar to malicious binaries we’ve seen in the past
  12. 12. What is Cerberus?Cerberus reduces the level of expertise required to domalware analysis. Ideal for first responders. STATIC ANALYSIS / DATA FLOW ANALYSIS YIELDS SIMILAR RESULTS AS DYNAMIC ANALYSISSTAGE ONE: Generic File/Metadata Analysis • Identifies potentially malicious code, generates threat score. Mythology Trivia:STAGE TWO: Disassembly Analysis Cerberus guards the gates of the • Runs elements of the code, without running actual underworld to prevent those who executable. To find out what the binary is capable of. have crossed into Hades from escaping.WORKS AGAINST… • Binaries that live on disk or network share In other words… he prevents bad • System Memory – unpacked binaries things from breaking free.
  13. 13. Cerberus Analysis Approach Cerberus uses a different approach than other products on the market because it doesn’t rely on : • Dynamic Analysis, Often not reliable, because the binary could recognize that it is being analyzed and perform a different action in order to intentionally fool the analyst. • Traditional Heuristics, such as the monitoring of modifications to the registry and the insertion of hooks into certain library or system interfaces, are not based on the fundamental characteristics of malware. • High false positive / false negative rates. • Signature-based /byte string analysis: cannot detect new malware or new variants and requires prior knowledge in the form of an action or byte string. NOTE: We are not relying on whitelists or signatures. We are able to assess behavior and identify intent without the above methodologies.
  14. 14. What Does Cerberus Do?STAGE ONE ANALYSIS STAGE TWO ANALYSIS Basic Disassembly Analysis:Executable Binary Analysis: • •Integrated disassembly engine• Product Name • •If using network functionality, potentially what host it• Product Version is communicating with and over what protocol(s)• Company Name, etc. • •If using network functionality, can it bypass proxy• Functions included in the Import Table servers? • Network • For functions that require usernames and/or • Process passwords, does the executable contain static string • Security indicating insider or advanced knowledge? • Registry• Dynamic Loading, etc. Advanced Disassembly Analysis:• Does the binary have high entropy (obfuscated)? • Automated unpacking• Does the binary have signatures of: • Automated code and data flow analysis • Internet Relay Chat (“IRC”) • •More advanced Functionality Interpretation • Shellcode • IP addresses and Domain Names Used • Cryptography (“Crypto”) • Debugger and Sandbox avoidance• Does the binary contain strings associated with • Command and Control Functionality autoruns? • Hooking Techniques• Digital Signature Verification • Arbitrary Code Execution • Host Forensic Artifacts • Registry Settings • Temp Files • Configuration Files
