Saint BlueHammer, the Hammer on the Guardian

Patron of over-privileged antivirus, disclosures without warning, and guardians who need guardians.

Life

On 2 April 2026 a researcher signing as Chaotic Eclipse published BlueHammer on GitHub, in open dispute with the Microsoft Security Response Center and without waiting for a fix. The flaw lay in Microsoft Defender, the very program meant to protect Windows: a local user could use it to gain elevated privileges. Microsoft fixed it as CVE-2026-33825, and CISA listed it as exploited in the wild, ransomware campaigns included.

Prayer

O Saint BlueHammer, who strikes with the guardian's own hammer, let those who defend us never become the front door. Amen.

How to celebrate

Celebrated by checking that the Defender antimalware platform really did update, rather than taking its word for it.

Whoever guards the castle holds the key to every room.
