Detects the creation or modification of registry run keys that establish persistence for the Prinz Eugen ransomware. The rule specifically looks for registry entries under 'Software\Microsoft\Windows\CurrentVersion\Run' that contain common environment variables (e.g., %APPDATA%, %TEMP%) and specific filenames or paths associated with Prinz Eugen ransomware (e.g., 'servertool', 'encrypt.exe', '\Music\', '\Desktop\').

Detects modifications to the 'Run' registry key for persistence, specifically looking for indicators associated with Prinz Eugen ransomware such as 'servertool', 'encrypt.exe', 'lock.exe', or 'ransom' in the registry value data. It excludes common legitimate paths to reduce false positives.

This rule detects modifications to specific registry keys that are commonly used for persistence by malware. The rule looks for Event ID 4657 (A registry value was modified) and checks if the ObjectName corresponds to known malicious registry paths related to Run keys, RunOnce, or service configurations. This indicates an attempt to establish persistence or alter system behavior for malicious purposes.

This rule detects potential persistence mechanisms related to browser extensions. It looks for processes launching Chrome or Edge with the '--load-extension' command-line argument, which can be used to load unpacked extensions. Additionally, it monitors registry modifications to 'ExtensionInstallForcelist' that contain 'http' or 'crx', indicating a forced installation of an extension, potentially from a remote source or a local file.

Detects the creation of the '.bun_ran' run-once marker in a temporary directory or suspicious Python '.pth' startup hooks (e.g., 'langchain_core-setup.pth') indicative of the Hades loader variant. The '.bun_ran' file acts as a marker for the loader, while '.pth' files can be used to inject malicious code into Python's import mechanism, achieving persistence or execution.

This rule detects modifications to Windows Registry Run keys (Run, RunOnce, RunOnceEx, Policies\Run) where the new value contains common scripting interpreters like PowerShell, cmd, cscript, or wscript, and the path is not within the System32 directory. This behavior is indicative of an adversary attempting to establish persistence by ensuring their malicious script or command executes upon user login.
