Really great blog post about bypassing BitLocker using "PXE soft reboot" (even if PXE boot is disabled in the BIOS). "Windows BitLocker -- Screwed without a Screwdriver" 👉 neodyme.io/en/blog/bitl... 👉 media.ccc.de/v/38c3-windo...

I updated the diagram representing the different Point and Print configurations and their exploitation on my blog. Hopefully, this should provide a better understanding of the whole "PrintNightmare" situation to both defenders and red teamers. 🤞

Interestingly enough, MS disabled the "Use my Windows user account" checkbox when connecting to Wi-Fi on the lock screen to address CVE-2024-38143 in the August Patch Tuesday. This change completely remediates the "Airstrike" attack as well. 🤯 support.microsoft.com/en-us/topic/...

🆕​ New PrivescCheck extended check! ℹ️​ The script can now enumerate dangerous default file extension associations, such as '.bat' or '.wsh'. ⚠️​ A manual review of the result is always recommended, but for the most part, it should be fine. github.com/itm4n/Prives...
