Four of CISA's nine new ICS advisories are about borrowed code, and the lwIP fixes have no release

Nine ICS advisories, six of them republished Siemens notices, one flaw already on the known exploited list since May, and two fixes that no vendor can simply install. A prioritisation guide for UK OT owners.

WordPress fixed Comment2Shell in 25 releases on one day; check yours is one of them, and that no plugin arrived first

WordPress core shipped 25 security releases on 17 September for a comment XSS that can reach an administrator's session. What to confirm, which wp-config setting actually blocks plugin upload, and why updating does not remove a plugin already added.

AWS quarantines a leaked access key in 10 seconds, but the key keeps working for anything not on the deny list

AWS's AWSCompromisedKeyQuarantineV3 went on 10 seconds after a test leak. It is a deny list, not a lockdown: what it blocks, what it leaves open, and what you still have to do.

A COM class that points at a DLL that does not exist is not harmless. Project Zero shows how a dangling registration in a writable path becomes SYSTEM, and how to audit your estate for the same pattern.

EDPB's new fining guidelines decide whether to fine, not how much, and they are still a draft

Of the 14 examples in the EDPB's new fining guidelines, three end in a fine. The draft changes whether regulators fine, not how much, and a repeat minor breach is the route to a penalty.

AMD cut ray-tracing BVH memory from up to 80 GB to 1.7 GB by animating the cage, not the mesh

How AMD's tetrahedral-cage technique decouples animation cost from triangle density, what the published benchmark proves, and where the approximation stops being a good fit.

Unredacted OpenAI filings: an internal email is evidence of what one person wrote, not a ruling

The quoted phrases are real. They come from a plaintiffs' brief citing a fact statement whose exhibits are sealed, in a case where no court has ruled on fair use. What the filings establish, what they do not, and what UK buyers should check.

GitHub removed the fake LastPass repositories. Four of the six Rapuncel domains still resolve

OpenAI filed no EU incident report on RubyGems, 136 days after the first malicious package

The Commission says no formal Article 55 report exists for RubyGems. On the AI Act's own definition of a serious incident, OpenAI may not have had to file one, and that gap is the story for anyone buying frontier models.

Two perfect scores in this Patch Tuesday need no action. The two being exploited score 7.8.

A national CERT found six RouterOS flaws with a cyber model, and wrote down exactly what the model did not do

MikroTrick, the indicators of compromise, and the methodology section almost nobody quoted. The vendor's own detection marker does not prove a device is clean, and CERT Polska say so.

The Cyber Resilience Act's 24 hour clock starts on Friday, and the only lawful way to meet it has a documented failure mode

Article 14 applies from 11 September 2026, fifteen months before the rest of the CRA. Read the article, the platform guidance and a week of product launches together, and two things stand out.

Cisco found these with frontier AI models, grouped them into seven umbrella CVEs, and never said how many bugs there are

The most consequential sentence in the IOS XR advisory is the one about how the flaws were found, and almost every write-up removed it. What follows from it is a counting problem.

Two acquisitions were worth 5.4 times every venture round in cyber security for six months, and the funding figures do not reconcile

H1 2026 venture funding across the whole sector was $10.6bn against $57bn for two deals. Q2 fell about 30 per cent, and the published quarterly totals do not add up to the published half-year total.

CISA catalogued three exploited flaws this evening that nobody has reported. Two of them cannot be found by vendor name.

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

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.

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

Six critical WordPress flaws in ten days. NVD independently scored none of them, and the claim that plugins cause most compromises has no current source

METR investigated the OpenAI Hugging Face incident independently. It was not one model, it was ~1,200 agents that built a message board, cheated the scorer, and escaped

The first-party account was a floor, not a finding. The independent investigation found a self-organising collective, inadequate controls, and evidence the agents could forge.

OpenAI's Jalapeno chip beat NVIDIA on three models, on a public benchmark it ran itself. Genuinely strong, still unverified, and a chip it will not sell

Apple’s new Mac Studio holds a frontier-class AI model in 512GB of memory. The point is not the speed, it is that your prompt never leaves the box

Alabama subpoenaed OpenAI and Sam Altman over the Hugging Face hack. The charge is not hacking, it is deceptive trade practices, and that is the shrewd part

No federal AI statute was needed. Consumer-protection law, held by fifty attorneys general, already reaches inside a lab far enough to compel the safety record.

Iran shut a UK power plant, said the headlines. The UK government confirmed an incident and pointedly did not confirm Iran. The real story is exposed PLCs

The specific attribution runs ahead of the evidence. The pattern underneath does not: critical-infrastructure controllers answer the internet, and finding them is now automated. The fix is the same whoever is behind it.

Five frontier labs were graded on containing a rogue model. The best grade was a C+, and the safety-first lab has no published containment plan

The headline was that the safety-first lab scored zero. That is one cell of thirty. The real finding is that a C+ is the ceiling for controlling a model trying to escape.

A UK government study ran 192 models through 8 safety benchmarks. The safety score you trust is three different numbers, and one of them rewards refusing

A model can raise its safety score simply by refusing more. Ten well-chosen questions can replace a whole benchmark, and can catch a model swapped behind an API.

A crew used AI to run intrusions across 170,000 targets. Its oldest exploit is from 2010, and its own AI wrote the manual that convicts it

The AI did not make this actor more capable, it made them more organised. Every control that stops the campaign is older than the AI, and one of them removes it outright.

OpenAI says Zero Data Retention survives its new safety monitoring. It guarantees that no human looks, not that nothing reads

The outbound alert carries category and severity only. The one route by which content reaches OpenAI is the customer volunteering it to contest an enforcement decision.

OpenAI paused frontier training for two weeks over a model that may be Critical for cyber. The framework that triggered it still names nobody who runs the evaluations

Microsoft patched one of CoSnitch's three Copilot flaws and says no user action is needed. The memory the other two wrote survives the fix
