Signatures

  • Deletes itself 1 IoCs
  • Modifies Watchdog functionality 1 TTPs 2 IoCs

    Malware like Mirai modifies the Watchdog to prevent it restarting an infected system.

    defense_evasion
  • Unexpected DNS network traffic destination 2 IoCs

    Network traffic to other servers than the configured DNS servers was detected on the DNS port.

  • Creates/modifies Cron job 1 TTPs 1 IoCs

    Cron allows running tasks on a schedule, and is commonly used for malware persistence.

    executionpersistenceprivilege_escalation
  • 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

  • Modifies systemd 2 TTPs 1 IoCs

    Adds/ modifies systemd service files. Likely to achieve persistence.

    persistenceprivilege_escalation
  • Reads MAC address of network interface 2 TTPs 1 IoCs

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

    defense_evasiondiscovery
  • Changes its process name 1 IoCs
  • Checks CPU configuration 1 TTPs 1 IoCs

    Checks CPU information which indicate if the system is a virtual machine.

    antivm
  • Reads system network configuration 1 TTPs 1 IoCs

    Uses contents of /proc filesystem to enumerate network settings.

    discovery
  • Enumerates kernel/hardware configuration 1 TTPs 1 IoCs

    Reads contents of /sys virtual filesystem to enumerate system information.

    discovery
  • Reads runtime system information 64 IoCs

    Reads data from /proc virtual filesystem.

    discovery
  • Writes file to tmp directory 1 IoCs

    Malware often drops required files in the /tmp directory.
