    executionpersistenceprivilege_escalation
  • Deletes log files 1 TTPs 5 IoCs

    Deletes log files on the system.

    defense_evasion
  • Enumerates active TCP sockets 1 TTPs 1 IoCs

    Gets active TCP sockets from /proc virtual filesystem.

    discovery
  • Enumerates running processes

    Discovers information about currently running processes on the system

  • Looks up external IP address via web service 1 TTPs 1 IoCs

    Uses a legitimate IP lookup service to find the infected system's external IP.

    discovery
  • Reads MAC address of network interface 2 TTPs 4 IoCs

    Fetches the MAC address of active network interfaces. May be used to detect known values for hypervisors.
