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 2 IoCs
  • Loads dropped DLL 18 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 4 IoCs

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

  • Drops file in Windows directory 2 IoCs
  • Executes a command shell one-liner 1 TTPs 9 IoCs

    Execution of a cmd.exe one-liner (/c "close" or /k "keep") is a common script/loader stage.

  • Reads the TCP/IP host and domain name from the registry 1 TTPs 6 IoCs

    The configured hostname and DNS domain identify the machine and are commonly collected to profile a host before it reports in.

  • Checks SCSI registry key(s) 3 TTPs 58 IoCs

    SCSI information is often read in order to detect sandboxing environments.

  • Delays execution with timeout.exe 1 IoCs
  • Kills process with taskkill 1 IoCs
  • Modifies registry class 64 IoCs
  • Scheduled Task/Job: Scheduled Task 1 TTPs 8 IoCs

    Schtasks is often used by malware for persistence or to perform post-infection execution.

  • Suspicious behavior: EnumeratesProcesses 13 IoCs
  • Suspicious behavior: GetForegroundWindowSpam 1 IoCs
  • Suspicious use of AdjustPrivilegeToken 41 IoCs
  • Suspicious use of FindShellTrayWindow 64 IoCs
  • Suspicious use of SendNotifyMessage 44 IoCs
  • Suspicious use of SetWindowsHookEx 4 IoCs
  • Suspicious use of WriteProcessMemory 21 IoCs
  • Uses Task Scheduler COM API 1 TTPs

    The Task Scheduler COM API can be used to schedule applications to run on boot or at set times.
