  3. Clipboard Surveillance and Application Monitoring: StilachiRAT keeps a close eye on clipboard activity, scooping up sensitive details like passwords and cryptocurrency keys. It also explores running apps and GUI windows to pull more system information[1][2].
  4. System Reconnaissance: The malware is a veritable crypt-miner, collecting intricate system details, such as OS specifics, BIOS serial numbers, and Active RDP sessions. This intel equips it for espionage and system manipulation[2][4].
