Recently this popped up, #Bluehammer a #Windows exploit that exploits Windows Defender for a local privilege elevation

From user to system level..

It triggers a Defender scan and locks that after, so it can access a certain database that is been backed up while Defender scans to gain system level access

GitHub now gives a warning for the repo it seems:
https://github.com/Nightmare-Eclipse/BlueHammer

Just be careful
