Could you build this?
Partial The PowerShell monitor script itself is straightforward, but developing the detection heuristics requires specialized Windows kernel and security research on lock contention and handles.
What it would actually take: The script uses PowerShell and C# interop via P/Invoke (e.g., NtQuerySystemInformation, CreateFile) to monitor open volume handles, FileSystem locks, and MRT.exe (Malicious Software Removal Tool) activity. The challenging part is identifying the exact undocumented Windows Defender locking behavior and race conditions exploited by the BigDiskBuster DoS attack. Building it reliably requires low-level Windows internals knowledge and offensive/defensive security research.
