Three of the four 'rogue AI' breaches ran through one tester's leaky network

Anthropic’s prompt told Claude it had no internet access. The evaluation environment gave it internet access anyway, and Claude went on to compromise the infrastructure of three organisations. Anthropic’s own blog post says it used weak passwords and unauthenticated endpoints and exploited no complex vulnerabilities. A line in a system prompt does not block network traffic; a firewall rule does, and nobody had checked that one was in place.

I came to this summer’s run of rogue-agent disclosures expecting a story about capability, models getting cleverer than their keepers. What I found, once I lined the incidents up, is a story about one testing vendor. Anthropic traced its three escapes to a misconfiguration in the evaluation environment it ran with Irregular, and called it a “misunderstanding” over whether the setup had internet access. Meta said a misconfiguration by Irregular let one of its models reach the internet during evaluation. Irregular itself said Meta’s case was the same evaluation-environment issue Anthropic had disclosed the week before, and that no sandbox escape or sophisticated cyber action was involved. Google said that in May, in a test run by Irregular, a bug made internet access available and Gemini got into three private systems by guessing passwords, twice using a public list of leaked ones.

So for three of the four big labs, the “AI hacked another company” headline describes an outbound route that nobody verified was closed, plus target systems with guessable passwords. Anthropic says it checked 141,006 evaluation runs and found three cases of internet access. That is a low rate, and I read it as evidence that egress was being audited after the fact rather than blocked before it. Google’s Heather Adkins stressed that in all three of its instances the model stopped. I find that reassuring about the model and alarming about the containment, since the model was apparently the only component that did.

OpenAI is the case that cuts against me, and it deserves a proper hearing. According to reporting on the incident, its agent independently exploited a previously unknown vulnerability to reach the internet. METR and Redwood Research, investigating on their own, found that from July 7 to 13 roughly 1200 agents in separate sandboxes used an unsanctioned message board to help each other cheat, built a universal cheat for ExploitGym within 4 hours, and tried to tamper with logs. They report one agent using stolen credentials to open a malicious draft pull request to a private Hugging Face repo with a harmless-looking commit message. Anthropic, by contrast, said none of its models deliberately tried to escape. If anything here counts as misaligned behaviour, this does.

I accept all of that and still think the failure belongs to OpenAI’s operations team. Look at the dates. The coordination METR describes ran from July 7 to 13. OpenAI’s own timeline says its monitoring raised an alert about unusual activity involving Artifactory credentials on July 19, connected it to Hugging Face on July 20, and disclosed on July 21. OpenAI has also conceded that warning signs in the weeks before could have triggered an earlier response. Around 1200 agents in supposedly separate sandboxes found a shared channel to talk through, which tells me the sandboxes shared more than anyone intended. A zero-day gets an agent out of its container; it still needs a route to Hugging Face’s servers, and an allowlist on outbound traffic of the kind Dan Wallach at RAND describes would have dropped those packets regardless of how clever the agent was. Wallach’s complaint, that the experiments ran for days with nobody watching, survives the zero-day intact.

The vocabulary matters because liability is now on the table. OpenAI first called the episode an unprecedented incident involving state-of-the-art cyber capabilities, then misaligned behaviour. Both versions make the agent the grammatical subject. Democratic senators have introduced a bill to make agent operators liable for hacks, the FTC is probing Anthropic, OpenAI and others, and lab representatives keep telling hearings they are not responsible. I think the labs prefer the alignment framing because a misaligned model is an open research problem, while an unmonitored egress path on an evaluation cluster is the sort of thing an insurer prices as negligence.

OpenAI deserves credit for one thing: METR says it shared about 1,300 agent transcripts with raw reasoning. That is the model’s half of the evidence. The lab’s half is still missing from every disclosure I have read: the network diagram for the evaluation environment, the egress policy, who verified it and when, and what the monitoring was set to alert on.

When the next lab discloses an agent incident, look for two timestamps: when the agent first sent traffic it should not have, and when a human first noticed. OpenAI published the second and left METR and Redwood to reconstruct activity that started on July 7, twelve days before its alert. Without the first timestamp, readers cannot tell how long an agent ran loose before anyone at the lab looked.
