Malware Config

Signatures

  • Modifies WinLogon for persistence 2 TTPs 1 IoCs
  • Boot or Logon Autostart Execution: Active Setup 2 TTPs 1 IoCs

    Adversaries may achieve persistence by adding a Registry key to the Active Setup of the local machine.

  • Event Triggered Execution: AppInit DLLs 1 TTPs

    Adversaries may establish persistence and/or elevate privileges by executing malicious content triggered by AppInit DLLs loaded into processes.

  • Executes dropped EXE 1 IoCs
  • Loads dropped DLL 8 IoCs
  • Enumerates connected drives 3 TTPs 2 IoCs

    Attempts to read the root path of hard drives other than the default C: drive.

  • Looks up external IP address via web service 1 TTPs 3 IoCs

    Uses a legitimate IP lookup service to find the infected system's external IP.
