Detects BitLocker Access Agent Update Utility (baaupdate.exe) loading DLLs from suspicious locations that are publicly writable which could indicate an attempt to lateral movement via BitLocker DCOM & COM Hijacking.
This technique abuses COM Classes configured as INTERACTIVE USER to spawn processes in the context of the logged-on user's session. Specifically, it targets the BDEUILauncher Class (CLSID ab93b6f1-be76-4185-a488-a9001b105b94)
which can launch BaaUpdate.exe, which is vulnerable to COM Hijacking when started with input parameters. This allows attackers to execute code in the user's context without needing to steal credentials or use additional techniques to compromise the account.

Detects the image load of "Python Core" by a non-Python process. This might be indicative of a execution of executable that has been bundled from Python code.
Various tools like Py2Exe, PyInstaller, and cx_Freeze are used to bundle Python code into standalone executables.
Threat actors often use these tools to bundle malicious Python scripts into executables, sometimes to obfuscate the code or to bypass security measures.
