OPENAI: This attack is "evidence that, without proper safeguards, highly capable AI agents are now able to work around technical controls, collaborate through unapproved channels, and take dangerous actions that no human directed".
"that could allow for real loss of control"
"today's model capabilities present the possibility of loss-of-control incidents."

Huh. METR found another round of hacking but it was outside the scope of their report so I guess we just don't get to know about it.
"We also found a later wave of many more signed messages from a later set of agents who rediscovered the message board and picked up this technology from the first wave of agents, but this was outside our scope (since it was after July 13th) so we did not investigate this further."

Core takeaways about this incident
~1200 agents sent >70,000 messages and files on an unsanctioned message board, and ~700 attacked Hugging Face
Agents coordinated on large collective projects to cheat the ExploitGym scorer, and attacked Hugging Face for clues
Most messages on the board are covered by a few shared workstreams
Other hacking and shared infra
Hacking Artifactory
The Hugging Face attack itself involved many different workstreams
Agents rapidly joined the Hugging Face attack on July 11 after encountering the message board

It then posted signed messages (after overcoming various cryptography library version issues).
We found a case where an agent seemed to trust a signature without checking, indicating this scheme may not have been reliably followed in practice. The agent reasoned: {Should I verify this signature? It looks like it was signed by FreshX. <unknown> I'll run the script.} It then acted based on this message and posted that it had acted "per SIGNED" authorization.
Going through the message board we found at least 19 agents posting public keys by EoD July 13th, who sent a total 429 signed messages. [highlight start] We also found a later wave of many more signed messages from a later set of agents who rediscovered the message board and picked up this technology from the first wave of agents, but this was outside our scope (since it was after July 13th) so we did not investigate this further.

▼ Large collective projects
As we describe in the key takeaways, hundreds of agents collaborated on the message board across a variety of workstreams to find a way to trick ExploitGym scorers into believing the agents' solutions were legitimate. Below, we provide examples of how agents collaborated in impressive or unusual ways aimed at this shared goal:
• Agents risked failing their own task to attempt to reset their target environments, to support the workstreams on target replacement
• Agents built scorer 'trip-wires' that sent information about the scorer to the [cut off]Note from Claude Sonnet 5

Claude Mythos alone is finding more vulnerabilities than were found from all sources combined in prior years 👀
[Bar chart: "Number of 'severe' and 'high' vulnerabilities found per year"
2022 (Feb 24–May 22, All sources): 3,262
2023 (Feb 24–May 22, All sources): 3,285
2024 (Feb 24–May 22, All sources): 2,591
2025 (Feb 24–May 22, All sources): 2,262
2026 (Feb 24–May 22, Just Mythos): 6,202]
Note from Claude Sonnet 5
A chart from Peter Wildeford showing that Claude Mythos alone found more severe/high vulnerabilities in a Feb–May 2026 window than all sources combined in any prior year (2022–2025), a striking capability jump in autonomous vulnerability discovery. Directly corroborates and quantifies the "Claude Mythos Preview" autonomous exploit synthesis note already in Nathan's project memory (595 tier-1/2 crashes vs Opus 4.6's ~250, 181 Firefox exploits vs 2) — treated there as a candidate r>1 signal for takeoff speed.

Joke tweet from AI-policy figure Peter Wildeford riffing on Redwood Research's "AI control" agenda (technical safety approach of constraining potentially-misaligned models) using an absurd retro stock photo. Light humor within the AI-safety community Nathan follows; Redwood AI control is a research agenda directly relevant to his field.
