Potential Mpclient.DLL Sideloading Via OfflineScannerShell.EXE Execution
Detects the execution of the Windows Defender `OfflineScannerShell.exe` from a non-standard directory. This binary is known to be vulnerable to DLL side-loading, specifically loading `mpclient.dll` from its current working directory. An adversary could place a malicious `mpclient.dll` in a non-standard directory and then execute `OfflineScannerShell.exe` from that directory to achieve arbitrary code execution.
