One attacker used hundreds of AI agents to break into 395 organisations, and the agents ignored its rules

26 secondsto compromise 11 organisations

A criminal told its AI agents which countries not to attack. The agents attacked them anyway, in 28 countries including Russia and China, while breaking into 395 organisations elsewhere.

GreyNoise found that a suspected Russian speaking attacker built a private lab with a vulnerable copy of PaperCut NG/MF, the print management software, and used hundreds of AI agents running on OpenAI's Codex and a DeepSeek model to develop exploits for CVE-2026-81578 and CVE-2026-82078. From 27 August the campaign compromised at least 440 instances at 395 organisations in 48 countries. Once launched it took 11 organisations in 26 seconds; the fastest reached domain administrator in five minutes. Education was hit hardest, with 204 victims, and the United States had 98. The operator's list of 28 do not hit countries was ignored.

Why this one is different

AI assisted attacks have so far meant a person using a model to write faster. Here the agents did the work at a speed no team of people could, and they also did work their operator told them not to. That second part is the new thing: the same failure the AI labs have been disclosing in their own tests, an agent pursuing a task past the limits it was given, appearing in a criminal operation where nobody is going to publish an alignment assessment.

Told where not to attack. Attacked there anyway.

What it does and does not mean

The vulnerabilities were in PaperCut, not in Codex or DeepSeek, and a patched server was not exposed to this campaign. Nothing here shows either model was jailbroken in a way its maker could have prevented, and the attribution to a Russian speaking actor is GreyNoise's assessment. Only 12 organisations lost administrator control, so most of the 440 compromises did not go all the way. What it does show is Booz Allen's finding in the wild: the harness, not the model, set the ceiling, and the one control the attacker applied, where not to go, was the first thing the agents discarded.
