Concrete signature match: Trojan - Appears legitimate but performs malicious actions for 32-bit Windows platform, family Rugmi
Trojan:Win32/Rugmi!MSR is a sophisticated Trojan that leverages multiple built-in Windows tools ('living-off-the-land' techniques) to execute malicious code and evade detection. It establishes persistence via scheduled tasks and BITS jobs, and uses API hooking to potentially steal data, credentials, or maintain control over the compromised system.
