Detects the creation of cook.pth or cook.py in Python site-packages or dist-packages directories by package managers or interpreters, followed by a Python interpreter execution on the same device within one hour. This pattern matches the malicious supply chain behavior observed in compromised LiteLLM versions (e.g., 1.107.0) utilizing .pth auto-import chains for persistence and execution.
Detects the loading of the 'truesight.sys' driver from non-standard or temporary locations. This activity is associated with a campaign where threat actors use a vulnerable version of this driver to terminate security products before deploying ransomware or RATs, a technique known as Bring Your Own Vulnerable Driver (BYOVD).
Detects successful Azure Active Directory (Entra ID) sign-ins using the device code flow where the originating device is neither registered nor trusted (managed or compliant), which may indicate suspicious authentication attempts or token abuse.
Detects the creation of a new Windows service (EventCode 7045) where the service binary path (ImagePath) points to the ProgramData directory, with exclusions for known legitimate paths such as Windows Defender, Package Cache, and Chocolatey.
Detects when a large number of virtual machines are powered off by a single user or initiator within a short timeframe, which can be an indicator of malicious availability interruption or virtualization disruption (such as ransomware preparation).
Detects Gryxa staging behavior where files are written across 2 or more distinct toolkit directories (such as WinRTCS, WER .wucache, and Diagnosis .etlcache) within a 1-hour window on a single device.
Detects potential defense evasion activity where Windows Defender configurations are modified or disabled, followed closely within 20 minutes by a silent, quiet, or unattended software uninstallation initiated by a script interpreter or command processor on the same device.
Detects the execution of Wireshark or tshark with command-line arguments indicating TLS key logging or packet capture file handling, followed shortly by a crash handler process (WerFault.exe or WerFaultSecure.exe) for the same process.
Detects potential data exfiltration activity where a device first exhibits usage of a remote monitoring and management (RMM) tool, followed by the execution of known data transfer or exfiltration utilities such as WinSCP or Rclone.
Correlates a Webcam.dll image load with VM-detection commands (such as queries for VirtualBox, VMware, vbox, vmtoolsd, Win32_ComputerSystem, or Win32_BIOS) executed by the same RegSvcs.exe process, which is characteristic of XWorm malware behavior.
