  • Family: AsyncRat

    AsyncRAT is designed to remotely monitor and control other computers written in C#.

  • Async RAT payload 1 IoCs
  • Checks computer location settings 2 TTPs 1 IoCs

    Looks up country code configured in the registry, likely geofence.

  • Executes dropped EXE 2 IoCs
  • Outbound SSH connection to public host 2 TTPs 4 IoCs

    SSH is used for remote access. This may indicate SSH host discovery, encrypted C2 traffic, or data exfiltration.

  • Enumerates physical storage devices 1 TTPs

    Attempts to interact with connected storage/optical drive(s).

  • Executes a command shell one-liner 1 TTPs 2 IoCs

    Execution of a cmd.exe one-liner (/c "close" or /k "keep") is a common script/loader stage.

  • System Location Discovery: System Language Discovery 1 TTPs 7 IoCs

    Attempt gather information about the system language of a victim in order to infer the geographical location of that host.

  • Delays execution with timeout.exe 1 IoCs
  • Scheduled Task/Job: Scheduled Task 1 TTPs 1 IoCs

    Schtasks is often used by malware for persistence or to perform post-infection execution.

  • Suspicious behavior: EnumeratesProcesses 23 IoCs
  • Suspicious use of AdjustPrivilegeToken 2 IoCs
  • Suspicious use of WriteProcessMemory 5 IoCs
