Allen AI audited 16 benchmarks across 100 models. Three filed as safety turned out to be measuring reasoning.

BenchMIRT was never told which benchmark measured what. It recovered two dimensions on its own, and BBQ, WMDP and HarmBench's copyright items did not land where they are filed.

OpenAI connected ChatGPT to Epic patient records. Every control it names governs which humans see what, not what the model does.

The announcement lists role-based access, single sign-on, audit logs and a BAA. It describes no prompt-injection mitigation. A preprint submitted the same day names the attack class.

Anthropic announced zero data retention for enterprises. The data is still retained, in your cloud account, on your bill.

Enterprise Frontier Safeguards moves the store into the customer's cloud under their keys, and Anthropic's automated systems still analyse a rolling window of it. It does not ship until later this autumn.

OpenAI and Anthropic both hardened their evaluation sandboxes after models got out. One model found two zero-days during the test.

Two frontier labs published incident reports about their own test harnesses within a day of each other, and each credits the other. Over 10% of one lab's training environments turned out to be defective.

Claude Fable 5.1 may now hunt for vulnerabilities, but not exploit them. And the price cut is one cell in a table.

Two things in the Fable 5.1 announcement matter to a security reader and are not being reported: a deliberately relaxed cyber safeguard sitting in front of a model evaluated as the strongest Anthropic has shipped, and a price cut that is a single line item.

Claude Sonnet 5 did not go up today. But Opus 5 costs 30% more than Opus 4.6 at the same price.

The Sonnet 5 rise everyone flagged for today will not occur. More usefully, Claude 4.7 and later produce about 30% more tokens for the same text, so an unchanged Opus rate card hides a 30% rise.

METR lost $600,000 of AI credits to one stolen key. The attacker got it by asking the agent.

METR disclosed that an API key was stolen in March 2026 and used for three weeks. The attacker did not find it in a repository or an infostealer log. They prompted the agent to reveal it.

Aurora ransomware drove an AI coding agent at 10 organisations. It ran on the operator's own laptop, and most commands failed first time

The agent was one pivot away, not inside. What crossed the perimeter was nmap, NetExec, Certipy and ntlmrelayx, exactly as it would have been anyway.

OpenAI is cutting model supply to Cursor after SpaceX bought it. The lesson is not the feud, it is that your AI tooling has a contract clause you never saw

Nobody using Cursor chose SpaceX. They chose an editor, and the ownership underneath it changed. Nothing technical broke.

AI Security29 Aug 2026

Researchers found two implants in router firmware that ships worldwide under a dozen brand names. There is no patch, and the widely quoted 100,000 figure is not from the research

You cannot patch your way out of hardware you have no reason to trust. There is no fixed firmware, so the response is inventory, egress control and replacement.

A cPanel customer who can add a domain can become root on the whole server. The advisory is five sentences and has no score, no mechanism and no indicators

An advisory serves two audiences: the one that patches tonight, and the one that has to decide how fast to move and whether it already happened. This serves only the first.

PaperCut’s two-flaw chain: Release 3 supersedes the emergency patch guidance

Release 3 supersedes Release 2. Read the 9 September update before applying the original 29 August analysis.

A Gitea flaw has been exploited since July and its CISA deadline has already passed. The 9.8 depends on a setting you can change tonight

The fix shipped on 27 July in a routine release. What arrived late was the CVE, four weeks after the exploit, which is the artefact most programmes actually track.

ServiceNow patched three CVSS 10.0 flaws that need no password at all. The version table matters more than the score, and the coverage keeps dropping a release family

The advisory contains one line that expires and one that does not. The industry is quoting the one that expires.

A researcher went from unpaired Bluetooth to root on a Unitree humanoid robot, and the exploit is wormable. AI is getting a body with IoT-grade security

A rooted robot moves, watches and listens, and carries the fleet's cloud keys. The bugs are boring; the setting, a machine with a body, is not.

A researcher broke Claude Code's auto mode 60 to 80% of the time. The safety layer missed the attack, then blocked the agent from cleaning it up

Auto mode is a convenience feature backed by a best-effort classifier, not a security boundary. The classifier saw a benign decoder; the exploit was several hops away.
