RoguePlanet in Microsoft Defender: PoC elevates privileges to SYSTEM on patched Windows

Colleagues, please note: a Proof of Concept for the RoguePlanet vulnerability in Microsoft Defender has been published.

- Who: anonymous 'Chaotic Eclipse' released the exploit; it is a race condition — unreliable, but yields SYSTEM on some machines.
- What: a successful exploit grants a SYSTEM shell and arbitrary code execution; confirmed on Windows 10/11 with June patches.
- Constraints/context: PoC currently fails on Windows Server due to ISO mounting; disclosures are ongoing and Microsoft urges coordination.

Why this matters: privilege escalation on patched systems; active exploitation in the wild has been reported.

How do you plan to respond?
