Hermit Crab Presentation

  1. 1. HERMIT CRAB Holistic Evidence Reconstruction (of) Malware Intrusion Techniques (for) Conducting Real-Time Analysis (of) Behavior
  2. 2. The Team Dr. Chao H. Chu, CEO Brian Matthew Matthew Reitz, Maisel, Dinkel CISO CIO Albert Chen, Server Admin
  3. 3. The Idea Network by XKCD Source: http://www.xkcd.com/350/
  4. 4. The Purpose Malware writers use obfuscation and sophisticated behavior to cover up their digital tracks and move quickly from host to host. XOR- "Fast-flux" Payload Polymorphism encrypted DNS migration verification shellcode
  5. 5. Static Analysis is Difficult "Finally, there is post-mortem analysis, the study of program behavior by looking at the after effects of execution. ... [It] is often the only tool available after an incident." -Dr. Wietse Zweitze Venema
  6. 6. Meet Frank the Hermit Crab “Forensic Response Analytic Network Kit” “Shout out to Tom Sennett”
  7. 7. Xen/Hermit Crab Architecture Xen hypervisor Ubuntu Hardy Server Ubuntu Dom0 ssh.d vnc Hardy Hardy Hardy OSSIM Heron 1 Heron 2 Heron 3
  8. 8. Open Source Security Information Management (OSSIM) OSSIM provides a strong correlation engine, detailed low, medium and high level visualization interfaces, and reporting and incident management tools, based on a set of defined assets such as hosts, networks, groups and services.
  9. 9. OSSIM Components Arpwatch • used for MAC anomaly detection. P0f • used for passive OS detection and OS change analysis. Nessus • used for vulnerability assessment and for cross correlation (IDS vs Security Scanner). Snort • the IDS, also used for cross correlation with nessus. Spade • the statistical packet anomaly detection engine. Used to gain knowledge about attacks without signatures. Ntop • which builds an impressive network information database from which we can identify aberrant behavior/anomaly detection. Nagios •  fed from the host asset database, it monitors host and service availability information. OSSEC •  integrity, rootkit, registry detection, and more.
