Hacker Wars - September 09, 2026

Your daily dose of infosec chaos

Microsoft just shipped the biggest Patch Tuesday in history, and the research community answered by dropping a fresh Defender zero-day on top of the pile. Google patched the seventh actively exploited Chrome zero-day of the year, and CISA gave MSPs a 48-hour homework deadline. Short version: this month’s change window is going to be a bloodbath.

Microsoft Shatters Patch Tuesday Record With 974 Fixes

Microsoft patched a record 974 vulnerabilities across Windows, Office, SQL, and friends, including two Windows zero-days already exploited in the wild. AI-assisted bug hunting is accelerating discovery, so expect these record batches - and your patch backlog - to keep growing.

What to do: Knock out the two actively exploited CVEs today, then triage the 58 flagged as likely to be exploited next.

New Defender Zero-Day ShieldCrash Grants SYSTEM Access

Hours after the September patches landed, a researcher going by Nightmare Eclipse published a working Microsoft Defender zero-day dubbed ShieldCrash that escalates privileges straight to SYSTEM. Releasing it right after Patch Tuesday maximizes the window where your fleet is half-patched.

What to do: Verify your Defender engine and platform versions, and watch for an out-of-band update - this one may not wait for October.

Chrome Hits Seventh Exploited Zero-Day Of The Year

Google patched 230 Chrome vulnerabilities, including another zero-day confirmed as actively exploited - lucky number seven since January. The browser remains everyone’s favorite front door, and 2026 is shaping up to be a record year for Chrome 0days.

What to do: Force the update now and enable auto-updates, especially on those VDIs and kiosks nobody admits to owning.

CISA Sounds Alarm On Actively Exploited N-able N-central Flaw

A maximum-severity pre-auth RCE in N-able N-central is being exploited in the wild and just landed on the CISA KEV catalog, with federal agencies ordered to patch by September 11. RMM platforms are a single point of failure: one 0day, hundreds of downstream customers.

What to do: If you run N-central, treat this as an emergency change; if you outsource to an MSP, ask them today what they are doing about it.

AI Sextortion Campaign Earns Ohio Man 15-Year Sentence

An Ohio man was handed 15 years in prison for cyberstalking and sextorting victims with AI-generated explicit content. A grim benchmark for deepfake abuse: the tooling is cheap, the crime is real, and now the sentences are too.

What to do: Include AI-generated abuse in awareness training, and make sure victims know to preserve evidence rather than pay.

That’s a wrap. Back tomorrow with more digital warfare.
