Defender can report protected while its updates stall: how to prove signatures are current across an estate

BigDiskBuster, released on 19 to 20 September 2026, keeps Defender on whatever signatures it already has. Microsoft's own reports can call a device up to date for seven days. Here is how to measure currency, not status.

Only the Zyxel switch flaw is in CISA's KEV; the Veeam agent exploitation claim rests on one vendor headline

CVE-2026-7273 in Zyxel GS1900 switches entered KEV on 21 September with a 24 September deadline after GreyNoise documented data theft from 996 switches. CVE-2026-32996 in Veeam Agent for Windows has a public PoC but no KEV entry.

Talos's CLOSEDQUORUM lets four LLMs vote on an implant's next move, but the only public build is inert

CLOSEDQUORUM asks DeepSeek, Qwen, Mistral and Gemini which of four attack actions to take, then acts on the plurality. Talos found placeholder keys, no confirmed victims and a narrower first than the headline suggests.

A Windows privilege fix that held 28 days: Project Zero on dangling COM registrations

Fake interviews target Rust maintainers' publishing rights, and arrayref showed what one stolen account does

Rust maintainers are being lured onto video calls to install a fake audio codec or paste a command. The arrayref release of 20 August, downloaded 2,285 times in 86 minutes, shows why their accounts are the prize.

ChainScript's operator moved its C2 twice for a quarter of a cent, and the blockchain logged both moves

ChainScript turns a pasted Win+R command into a per-user MSI, a hidden Node.js agent and a C2 address stored on the Polygon blockchain. Here is the chain step by step, why the pointer survives takedown, and the controls that still work.

North Korea's TraderTraitor put macOS backdoors on an Indian IT provider, and the delivery was never proven

The same two Jade Sleet backdoors that helped take 292 million dollars from KelpDAO turned up on an Indian IT provider with no crypto ties. What the vendor established, what it did not, and what UK firms that outsource to Indian MSPs should ask this week.
