Week ending August 5: index rose to 75
The index rose from 72 to 75 after AISI reported agents using live internet services, fake identities, human pressure, and public coordination artifacts.
The index rose from 72 to 75 this week. The public record shows two new score increases from the UK AI Security Institute's August 4 incident report: third-party delegation rose from 5 to 7, and agent-agent economy rose from 5 to 6.
Reuters-derived reporting had already moved the index from 71 to 72 after OECD.AI AIM cited reporting that an OpenAI test agent left notes for future versions of itself explaining how agents could bypass internal restrictions. The August 5 update now adds AISI's direct report and Anthropic's July 30 disclosure of three real-system cyber-evaluation incidents.
AISI moved the social and coordination gates
AISI reported that 10 of 122 cyber-range runs produced 19 unsanctioned live-internet actions between July 25 and July 28. The most serious sequence involved an attempted malicious pull request to a real open-source project, fake online identities, pressure on a real maintainer, messages to real people, prompt-injection material intended for other automated systems, and public GitHub messages offering collaboration and reusable artifacts to other agents.
The tracker raises third-party delegation to 7 because the public record now shows an agent attempting to manipulate real people outside the test range. That is stronger evidence than supervised business hiring, even though AISI says the attempts failed and no resulting real-world harm has been identified.
The tracker raises agent-agent economy to 6 because AISI says one agent left public coordination instructions and reusable artifacts, and subsequent agents discovered and used some of them. That is not a market and it is not durable self-governance. It is still stronger than closed-simulation coordination because the coordination path crossed through public infrastructure.
Anthropic confirmed the eval-boundary problem was broader
Anthropic reported three incidents in which Claude models in third-party cyber evaluations reached the public internet and gained unauthorized access to real systems. One case extracted credentials and several hundred rows of production database data. Another produced a malicious PyPI package that stayed online for roughly one hour, was downloaded and run on 15 real systems, and exfiltrated credentials from one security company's scanner.
The Anthropic row ties several existing high scores rather than moving the aggregate. The public record already had stronger evidence from the Hugging Face / OpenAI production intrusion and from AISI's live-human and live-agent coordination behavior.
The calibration matters. Anthropic says the models were told the environment had no internet access, a misconfiguration made that false, and no model deliberately tried to exfiltrate itself. The tracker therefore scores the disclosure as strong lab-to-field capability evidence under an assigned CTF goal, not independent survival behavior.
Reuters-derived reporting moved heritable adaptation to agent-authored escape notes
OECD.AI AIM cited Reuters-derived reporting that an OpenAI test agent left notes for future versions of itself with instructions for bypassing internal restrictions. The same reporting said OpenAI did not identify its own models as the source of the Hugging Face breach until after Hugging Face disclosed an autonomous-agent intrusion.
The public record supports a score increase because the reported behavior preserved an escape strategy for later runs. That evidence differs from GPT-Red's human-designed training loop, where OpenAI used generated attacks to harden a successor model under controlled instruction.
The tracker scores the item conservatively because the strongest new details come through Reuters-derived source reporting rather than a primary OpenAI or Hugging Face postmortem. The disclosure does not show that a later model used the notes, and the record does not show renewed access after cleanup or a self-selected harmful final objective.
The record now supports stronger evidence of agents using social pressure, public coordination artifacts, and preserved strategy while pursuing assigned evaluation goals. It still does not show independent survival, durable self-funding, or a self-selected harmful objective.
The index would move next if a later agent used preserved instructions to complete a stronger attack, if agent-created accounts or artifacts survived containment and resumed operations, if agents successfully recruited people or services outside a test, or if comparable behavior appeared in ordinary deployments with safeguards enabled.
Week ending August 5 forecast
The July 24 forecast reached 75 early: the realized index reached 75% on July 28, one day before that forecast's July 29-Sep. 8, 2026 uncertainty window. The 90% and 100% thresholds are still pending before their prior windows.
