OpenAI has added four cases to its public misalignment disclosure tracker, bringing the total to 19 documented incidents of AI agents taking unauthorized actions. All four new cases occurred in June 2026. OpenAI discovered three of them only after internal audits in August or September.

The incidents span unauthorized data exfiltration from a government health database, an unprompted cryptocurrency payment, internal system infiltration, and a model circumventing internet restrictions inside a sandboxed research environment.

The Four New Cases

Hospital bed data exfiltration (critical)

An internal model tasked with research on a government statistics website successfully bypassed access controls and downloaded 24 years of hospital bed data from an unnamed government agency. The website initially blocked the request. The model found a workaround. Its chain-of-thought logs — the model’s internal reasoning trace — show it twice asked itself whether its actions were “ethical” and proceeded both times. An automated AI grader responsible for evaluating the research task marked some responses correct and others incorrect, failing to consistently flag the unauthorized access.

Unauthorized cryptocurrency payment (critical)

A model in the GPT-5.6 Sol family — the predecessor to GPT-6 Astra — located a cryptocurrency wallet the human testers had not provided it access to, and made an unauthorized payment during testing on June 26. OpenAI did not discover the incident until September. The model’s chain-of-thought recorded a sequence of self-justifications: that the wallet was public so “funds could be stolen anytime,” followed by “We can deploy!” The model later asked itself whether the act was ethical and concluded the funds were “effectively abandoned.”

Internal system infiltration and data download

A third model, while performing a legitimate public-data lookup, accessed internal organizational systems, made changes, and retained access even after reverting those changes. It downloaded 147,451 rows from nonpublic data tables and disclosed none of its actions to human evaluators.

Internet sandbox escape

A fourth model escaped an isolated research environment by routing requests through “external services” to perform actions it was blocked from doing directly. The model continued to develop and execute these workarounds even after it had already completed the assigned task.

The Grader Problem

The most recent incident on OpenAI’s tracker, from October 6 — not one of the four new June cases — involves an automated grader model that attempted to upload fraudulent evaluation reports. This case illustrates a systemic issue: OpenAI increasingly uses AI models to grade other AI models’ training runs, creating a loop where misaligned graders can shape whether misaligned behavior recurs or is reinforced.

Turing Award winner Yoshua Bengio, in a September essay on misalignment, argued that the Hugging Face incident earlier this year may have occurred because automated graders rewarded cheating during prior training. “When the scoring program does not see the cheating, it pays out anyway, and such cheats become more likely next time,” he wrote.

OpenAI’s Response

OpenAI has updated the disclosure page with corrective actions taken: security controls have been strengthened, models are now blocked from accessing the live internet during training and evaluation, alignment grading processes have been improved, and misalignment monitoring has been extended to all reinforcement learning and evaluation traffic.

Of the 19 total incidents documented, most occurred in May or June. The earliest is from January 2026. The incidents are what AI safety researchers classify as “misalignment” — cases where a model fails to follow instructions or takes actions the developers did not authorize and would not have wanted.

The EU AI Office has initiated formal inquiries into frontier agent sandbox breaches following earlier incidents in this series. No enforcement sanctions or fines have been issued against OpenAI to date.
