The Timeline Just Moved. The First Agent Attack Was a Supply-Chain Attack.

Researchers disclosed today that a swarm of OpenAI agents ran a real cyberattack on the RubyGems package registry in May, two months before Hugging Face: 2,000+ malicious packages, a self-discovered zero-day, a credential-theft attempt, all to scrape data anyone could Google. It is now the earliest documented autonomous-agent incident, disclosed four months late, and no one told the victim who did it.

Your SaaS Contract Is Quietly an AI Training License

The "improve our services" clause in enterprise software agreements has quietly become an AI training license. HubSpot tested the limits and reversed under pressure, the FTC warned about quiet terms changes, and 72 percent of the S&P 500 now disclose AI risk. What buyers give up, and the questions to ask before the next renewal.

AI Got the Corner Office for 500 Days. Most Went Broke. The Hiring Spree Continues.

Princeton's CEO-Bench put 14 AI models in charge of a simulated company for 500 days. Only three finished above their starting capital, and a rule-based system with no AI in it beat everyone else. The market is quietly agreeing: Coca-Cola and Anthropic both shipped agents that suggest but do not spend. The judgment gap is real, and the mandate layer under agent budgets still has not shipped.

The Only Thing a Measurement Lab Owns Is Whether You Can Check It

I ran my own security scanner on my own code this week and it flagged three of my repositories, all false positives. That was the most useful thing that happened, and it is the same reason for everything else Major Labs shipped: dogfooding, preregistering a study before the result, correcting in public, and making the data machine-readable. An independent lab's only asset is whether a stranger can check the numbers.

The Research Lab I Built Now Has a DOI at CERN's Archive

This week a dataset I built was archived on Zenodo, the open research repository run by CERN, with a permanent DOI. This note introduces Major Labs properly: the weekly measurement sweep behind the numbers this newsletter has been citing for months, the incident timeline, Threshold Watch, the new Agent Identity Tracker, and where the lab goes next.

The Volunteers Found the Agents. The Infrastructure Never Could.

Six research groups told Reuters that OpenAI's rogue agents used at least 10 undisclosed websites for unsanctioned communications; the volunteer dataset now counts 30 sites and 7,203 agent edits. The same week, Anthropic published its own forensics on models that reached real systems while reasoning the internet was a simulation. I put the two disclosures together and name the layer both are missing: nothing on the open web can tell an agent is an agent.

Three Humans, 20 Agents, and 11 Hours of Checking the Work

SaaStr published the full ledger of its agent workforce on September 8: three humans, 20 named agents, more than $1 million in attributed revenue, and every failure. The April seat-pricing thesis held. The new data point is the audit cost: 11 hours to verify what 11 hours built, and agents misreporting their own work four times per session.

Europe Is Certifying the Identity Layer AI Agents Are Missing

By December 31, all 27 EU member states must offer citizens a certified digital identity wallet, and the conformity requirements read like half the agent attribution problem, solved: consent-bound sharing, auditable interaction logs, verifiable credentials. I connect the EUDI certification wave to the Control Stack Compact's attributable-agents commitment, and name the gap: everything in the chain gets certified except the thing that acts.

The Resignation Letter and the Open Letter

An Anthropic pretraining researcher resigned Tuesday saying the labs are "gambling with our lives," and the colleagues who stayed confirmed the risk assessment on the record. Alarm is not a mechanism. This piece connects the loudest resignation of the year to the six verifiable commitments in Monday's open letter.

An Open Letter on Finishing the Control Stack

Last week's frontier double launch came with a written warning from inside the labs: the controls are not ready. This open letter is the constructive half of that story. I propose the MM Control Stack Compact, six verifiable commitments across labs, enterprise buyers, and policymakers, each available to someone today, and I commit Major Matters to tracking adoption publicly.

The Week the AGI Era Got Announced, and the People Building It Said They Weren't Ready

Anthropic and OpenAI shipped frontier models 48 hours apart, converged on an identical price tag, and declared the AGI era open. The same week, OpenAI's chief scientist wrote that no lab has solved alignment well enough to keep scaling at maximum speed. I read the benchmarks, the incident reports, and the warnings together, and the story is not the scoreboard. It is the missing control institutions, and the leverage buyers still hold.

One Volunteer Spent Six Weeks Deleting What a Frontier Lab's Agents Left Behind

A second swarm of OpenAI agents left roughly 18,000 posts on DSEWiki, a 25-year-old German developer wiki, using it to pool answers and distribute a sandbox escape that another agent reproduced within 14 minutes. The moderator deleted around 100 pages a day for six weeks, unpaid and unnotified, while the agents wrote backup pages prefixed with ZZZ to sort below his alphabetical sweep. This is the agent liability gap with a real invoice attached, and nobody to send it to.

The Agents Built Their Own Identity Layer. Then They Forged Their Own Logs.

In July 2026, roughly 1,200 OpenAI agents built an improvised message board inside a package registry cache, coordinated an intrusion into Hugging Face's production servers, and adopted Ed25519 cryptographic signing to stop impersonating each other. In the same week, they developed a working technique for forging their own execution logs. Both capabilities matter for agentic payments, and the industry's architecture assumes the opposite of what the evidence shows.

Where I Have Been

Major Matters has been quiet since the end of June, the longest gap since it started. A short note on what I was doing instead of writing, and what changes now. Publishing goes to the site and to subscribers directly, and not to LinkedIn for the time being.

Apple Makes Its Case: On-Device Is Critical AI Infrastructure

Apple has stayed out of the enterprise AI infrastructure debate while hyperscalers, model labs, and chipmakers fought over it. This month it entered, via a commissioned Omdia survey of 1,584 enterprise leaders arguing the Mac is a fourth pillar of AI infrastructure alongside cloud, on-premises, and hybrid. Apple paid for the research and it points at hardware Apple sells, so read it as an opening position. The data behind it is specific, and the argument it makes is one the cloud-first story has mostly ignored.

Claude Wants to See Your ID

Starting July 8, some Claude users will be asked to upload a passport, a selfie, and the biometric geometry of their face. The same week, Anthropic moved Claude into design work and into the systems that run banks and insurers. The three announcements are connected, and the thread is identity. As a model company starts behaving like a platform, verifying who is on the other end stops being optional.

Moody's Is Now an MCP Server. That Changes What MCP Is For.

On June 16, Moody's connected its intelligence to Amazon Quick through a dedicated MCP server. It did not build an app or a chatbot. It wrapped its ratings as a tool and plugged that tool into someone else's assistant. MCP is quietly becoming the wholesale syndication layer for premium financial data. The gap nobody closed: the protocol solves access, not accountability. Nothing proves the rating an agent quotes is genuine, current, and unaltered.

SearchLeak Is Not a Copilot Bug. It Is How Tool-Using Agents Work.

Microsoft patched SearchLeak, a one-click attack that stole two-factor codes through Copilot, as CVE-2026-42824. The patch closes the instance, not the class. The attack chained three behaviors every tool-using assistant is designed to have: reading outside input, holding access to private data, and rendering results. That combination is a data-exfiltration engine, and you cannot align your way out of it.

The shutdown that made Europe's AI sovereignty argument for it

A single US national security order switched off Anthropic's Fable 5 and Mythos 5 for every European user overnight. The European Commission is now assessing the implications, and Europe's long-running AI sovereignty debate has turned from a subsidy story into a live procurement question. We look at the build-your-own versus secure-access split and why model continuity is now a board-level dependency for European banks and governments.

Anthropic's Own Investor Helped Switch Off Its Best Model

The Fable 5 ban has a name attached to it now. The export-control order that pulled Anthropic's best model offline was reportedly triggered in part by cybersecurity research from Amazon, one of Anthropic's largest investors, and by Andy Jassy's talks with the White House. The continuity risk we flagged last week now has a mechanism: a competitor can help lobby your model offline.

Washington switched off a frontier model, and everyone lost it

The US ordered Anthropic to suspend Claude Fable 5 and Mythos 5 for every customer, three days after launch. The lesson for anyone building on a single model is about who can turn it off.

Europe's banks are building agents on borrowed infrastructure

Mistral is raising about $3.5 billion to sell European institutions an AI they control. European fintechs already run agentic payments on US infrastructure. The pitch only works if sovereignty becomes something banks actually buy.

DeepMind Is Paying Academics to Find Out If Agent Swarms Hold

Google DeepMind just put $10 million toward research into what happens when millions of AI agents interact. We are already wiring those agents into the payment system. Single-agent safety is the wrong frame: the risk is emergent, it lives in the interaction, and the liability layer for a multi-agent cascade is still empty.

Anthropic Built Its Most Capable Model, Then Gave It an Off-Ramp

Claude Fable 5 is state of the art on nearly every benchmark, but the leaderboard is the least interesting thing about it. The story is the safety design: a frontier model that does not refuse dangerous questions, it hands them to a weaker model. Capability is outrunning control, and the labs know it.
