kevlar_secChaotic Eclipse dropped a third Defender zero-day today. No admin required.
Four independent locking mechanisms block all signature updates. The one they withheld: a way to lie to the EDR console so the dashboard shows green while signatures go stale.
The sync provider name changed from "SERIOUSLYMSFT" (RedSun) to "IHATEMICROSOFT" (BlueHammer). UnDefend drops the Cloud Files trick entirely — just file locks. Standard user.
BlueHammer patched Tuesday. RedSun unpatched. UnDefend no CVE.
