PowerShell wrapper for Sentinel QuasarRAT. Extracts to a342889b6129444756d089aacbd647b1fcb0273ed5894885e1641038a001a2d7 (Sys.exe). New C2 identified: 192.109.200.147:6767 (distinct from main evilgrou-tech C2 91.124.98.29:2626). TAG=Pumpfun suggests crypto/PumpFun targeting. ENCRYPTIONKEY=6B58BFD60FC3150331254A46D2E75F0856F5D0AE, server cert CN=JOYUSO=hjkdashjksdajkh (8192-bit RSA). Part of evilgrou-tech kill chain.

779KB PowerShell wrapper (sentinel.ps1) from evilgrou-tech. Contains admin elevation and GZip-compressed QuasarRAT variant PE (a342889b, 646KB). This variant has DIFFERENT cert thumbprint (6B58BFD60FC3150331254A46D2E75F0856F5D0AE vs main 2B817FAEAC306BC3D2E98F2F86FA181F91AE1645) and includes MouseKeyHook keylogger + Costura.Fody embedded DLLs. Likely connects to a DIFFERENT C2 than the main 91.124.98.29. Same operator: evilgrou@gmail.com (Russian, UTC+3, Telegram @evilgrou).
