Malware Config

Signatures

  • Creates/modifies Cron job 1 TTPs 1 IoCs

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

  • Creates/modifies environment variables 1 TTPs 1 IoCs

    Creating/modifying environment variables is a common persistence mechanism.

  • 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.

  • Write file to user bin folder 1 IoCs
  • Modifies Bash startup script 2 TTPs 1 IoCs
  • Changes its process name 4 IoCs
  • Reads runtime system information 64 IoCs

    Reads data from /proc virtual filesystem.

  • Writes file to tmp directory 2 IoCs

    Malware often drops required files in the /tmp directory.
