Threat Hunting of CrimsonRAT from APT36/Transparent Tribe group

As part of my research among new malware and widespread active vulnerabilities it was interesting to work on actives of Crimson RAT which was active and prominent in some countries in Asian region.

This trojan was actively used by APT36 (aka Transparent Tribe) among some other tools. The malware/group was targeting various government entities as well as high profile educational institutes like IITs, that made it more interesting to conduct a deep dive in this RAT.

This presentation will cover various aspects about CrimsonRAT Malware Analysis & Threat Hunting.

  • Types of issues faced during the Reverse Engineering of the malware.
  • Points like basic analysis, issues with sandbox executions, sandbox evasion capabilities, persistence methods.
  • Type of payloads and different secondary payloads analysis, behavioural indicators, threat hunting process,
  • How threat hunting queries are created,
  • How threat hunting output is further used and prevention against the malware.
