Microsoft's directory service for Windows networks, a frequent target of privilege-escalation attacks and misconfigurations like MachineAccountQuota.
Microsoft patched CVE-2026-69730, a CVSS 9.8 remote code execution flaw in the Windows DNS Server role reachable with one unauthenticated packet to port 53. In most Active Directory shops that role runs on the domain controller, so the box answering on port 53 also holds the identity database.

Australia's ASD ACSC wrote the guidance with CISA, the NSA, Canada's CCCS and the British and New Zealand cyber centres, pairing the 17 most common Active Directory compromise techniques with mitigations.

Huntress's second post on Active Directory Rights Management Service traces every protected document back to one private key. The certificate runs 255 years, the key has no expiry, and the product ships no way to rotate it.

GreyNoise says a likely Russian-speaking actor built and tested PaperCut exploits in a lab, then ran hundreds of agents on a Codex harness with a DeepSeek model against 440 servers in 48 countries. The sending infrastructure was already on its watchlist.

Six weeks of lab work on a role Microsoft no longer develops but still supports on Windows Server 2025 ended with an offline decrypt of a protected document and a private key stamped valid until 2258 that nobody can rotate.

A public proof-of-concept for CVE-2026-54121 shows an Enterprise CA vouching for a forged Domain Controller identity. Microsoft's July 14 fix adds a missing check, not judgement.
