Monday 24 August

Editorial hero for the quantization-you-may-not-get-the-model-you-paid-for briefing.

AI Security24 Aug 2026

The DeepSeek or Claude you bought through a reseller may be quantized down. Same name, same price, a measurably worse model, and nothing on the endpoint says so

You may be paying for a full model and receiving a compressed copy. The only tell is a benchmark against the model maker direct, and it is cheap to run.

A battered brown cardboard parcel on a dark studio background, its top buried under many overlapping blank white shipping labels stacked and peeling, showing it has been relabelled and forwarded many times. Text in the dark right reads: you pay one hop, you inherit seven, LLM API reseller supply chain, arXiv 2608.20732.

AI Security24 Aug 2026

You buy model access from one reseller. Your prompt can pass through seven you were never told about, and a timing trick just proved it

The feature that makes inference cheap, prefix caching, is the side channel that reveals who really serves your prompt. Two resellers can be one basket in two coats.

Sunday 23 August

A heavy steel bank-vault door with a wheel lock and thick hinges, standing slightly ajar in a dark concrete chamber, cold cyan light spilling from the gap where it has not fully closed. Text in the dark right reads: the last door is the open one, Guidelight AI control assessment, August 2026.

AI Security23 Aug 2026

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.

Saturday 22 August

A single white beam of light entering a glass prism on a dark laboratory stand and splitting into three diverging beams, one cyan, one amber, one red, against a near-black background. Text in the dark right reads: one score in, three answers out, arXiv 2608.05086, UK AI Security Institute.

AI Security22 Aug 2026

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.

Friday 21 August

A macro image of a square silicon chip covered in a fine gold microelectrode grid, with a translucent pinkish film of living cultured brain cells spread across it, faint branching filaments glowing warm amber against the cool cyan-lit chip edge and a black background. In the dark lower right, the line: a computer made of living cells, no regulator cleanly owns it.

AI Security21 Aug 2026

Singapore unveiled a data centre made of living human neurons. It is lower power only if you measure the cell and not the box, and no regulator cleanly owns it

A CL1 unit draws up to 1,000 watts, most of it keeping cells alive. The efficiency case is about the neuron. A data centre pays for the box.

A heavy dark metal storage drawer pulled open in near darkness, its interior an empty black space, a warm brass rail catching the light along its runner. In the dark lower right, the line: your data, your cloud, still read either way.

AI Security21 Aug 2026

Anthropic will let enterprises keep their AI data on their own cloud. The 30-day retention it fought pushback over does not go away, it moves

Anthropic called its own shot, warning in writing that its retention policy posed risks if competitors did not follow. Days later OpenAI appeared not to, and Anthropic softened to bring-your-own-cloud.

A robotic gripper arm in cool metal, lit by cyan light, lifting one rusted antique skeleton key from a wooden tray holding a row of similar old keys, against a near-black background. In the dark right of the frame, white text reads: the AI is new, the exploits are not. Below it, UAT-10147, oldest bug 2010.

AI Security21 Aug 2026

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.

AI Security20 Aug 2026

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.

A dark navy chart headed The rule says 60 days, it says it twice. Two cyan outlined bars each labelled 60 days run consecutively, the first from associate to covered entity and the second from covered entity to you. Beneath them a longer red bar reads 131 days actually elapsed. A timeline below marks 16 March discovery, 24 June data determined, and 25 July letters.

AI Security20 Aug 2026

CareCloud's breach reached 3.75 million people and took 131 days to reach them. The rule it was measured against sets 60 days twice

Discovery on 16 March, data determined on 24 June, letters from 25 July. The regulation anchors both clocks to knowledge rather than to the end of forensics.

AI Security19 Aug 2026

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

Monitoring now costs roughly 20% of the inference compute it watches. OpenAI has answered two of the three questions this site put to it, both outside the document that carries the commitments.

An illustration on a deep navy ground. On the left, a dark terminal window with an amber outlined command line reading curl minus X PUT minus minus data dash binary at dash. A glowing amber bar leaves the window and breaks into four separate cubes, labelled upload id, chunk index and total chunks, flowing toward a loose grid of six identical empty cyan outlined rectangles on the right, labelled 31 domains one registrar and none registered in 2026. A caption under the terminal reads staged archive split into chunks.

AI Security19 Aug 2026

Microsoft says MacSync Stealer rotates domains too fast to block. All 31 in its own list share one registrar and none was registered this year

Rotation and registration are different activities. Fourteen of the 31 domains were registered on two days in late 2025, at the same registrar as the rest.

Tuesday 18 August

An illustration on a deep navy ground. On the left, a glassy browser window whose address bar reads copilot dot microsoft dot com slash question mark q equals, followed by an ampersand and autorun equals 1 picked out in amber, above greyed placeholder lines and an empty box reading Message Copilot. A glowing amber ribbon streams out of the window from left to right, carrying three lit tiles bearing an envelope, a calendar and a document, labelled connected apps read with granted access. The ribbon ends at a glowing cyan outlined capsule of joined circles labelled attacker endpoint. A caption under the window reads prompt fires on page load.

AI Security18 Aug 2026

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

Microsoft's advisory sets customer action required to false. That is correct about the vulnerability and wrong about the incident, and the difference is a memory entry no runbook clears.
