  • Executes dropped EXE 2 IoCs
  • Outbound SSH connection to public host 2 TTPs 5 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
