China is investigating DeepSeek and Moonshot over routing to Claude, on evidence only Anthropic holds

EvilTokens takedown: 226 domains in the court order, two arrests, and a phish MFA cannot stop

The court order lists 226 domains. Microsoft's own sworn declaration says device code theft cannot be stopped by multifactor authentication. What breaks the chain is a Conditional Access setting many tenants have never switched on.

Threat Intel22 Sept 2026

SharePoint CVE-2026-65660 went from spoofing to code execution 16 days after release, filed as informational

Microsoft relabelled CVE-2026-65660 from spoofing (6.5) to remote code execution (8.8) 16 days after release. The fix was always in the August updates; the risk is teams that sorted by the first label.

Grok 4.7: 38% on Terminal-Bench in xAI's harness, 26% in an independent one, and on by default in Copilot

California's seven data centre laws cap nothing, and state energy reporting skips every site under 10 MW

Alinubx.sys carries a 2023 Microsoft hardware signature, kills 145 AV and EDR processes, and was not on Microsoft's vulnerable driver blocklist at publication. What the blocklist, HVCI and the ASR rule do and do not cover.

Compliance and Regulation22 Sept 2026

Bessent says OpenAI's managers answer for its agents, but names no law that would charge them

Bessent rejects a liability shield for AI labs, but his remarks name no offence, bill or prosecutor. We read the transcript, correct a misattributed quote, and test UK failure to prevent fraud and the new senior manager rule against AI agents.
