 Tool: COMpfun
Names
COMpfun
Reductor RAT
Category Malware
Type Backdoor, Keylogger, Info stealer
Description
(G-Data) G DATA SecurityLabs experts discovered a new Remote Administration Tool, which
we dubbed COMpfun. This RAT supports 32-bit and 64-bit Windows versions, up to the
Windows 8 operating system. The features are rather common for today’s espionage tools: file
management (download and upload), screenshot taking, Keylogger functionality, code
execution possibility and more. It uses the HTTPS and an asymmetric encryption (RSA) to
communicate with the command and control server. The big novelty is the persistence
mechanism: the malware hijacks a legitimate COM object in order to be injected into the
processes of the compromised system. And it is remarkable, that this hijacking action does not
need administrator rights. With this RAT, Attackers could spy on an infected system for quite a
long time, as this detection evasion and persistence mechanism is indeed pretty advanced!
