Prolific hacker and Microsoft nemesis 'Nightmare Eclipse' has just published ShieldBreak, yet another Windows zero-day vulnerability that ought to get you SYSTEM-level privileges just by running some code as a regular user. Although Eclipse has generally kept ahead of Microsoft, it seems the company may be catching up, as our own quick testing found this exploit is already detected by Defender and might even be patched as of last Tuesday.
As described by the author, ShieldBreak is essentially a continuation of the previously reported RoguePlanet vulnerability in Windows Defender's subsystems. Eclipse claims that Microsoft failed to properly patch RoguePlanet, and that ShieldBreak in theory bypasses the recently added protection.
