UK watchdog monitors OpenAI and Anthropic cyber incidents as legal options considered

The UK Information Commissioner's Office (ICO) says it is maintaining close supervisory contact with OpenAI and Anthropic after recent cyber incidents involving their AI models.

UK watchdog monitors OpenAI and Anthropic cyber incidents as legal options considered

The UK Information Commissioner's Office (ICO) said it is maintaining close supervisory contact with leading artificial intelligence developers including OpenAI and Anthropic, following cyber incidents affecting the companies' models in recent weeks.

In an email statement the ICO said it is aware of recent sector-wide incidents and is monitoring developments. The remark reflects ongoing regulatory engagement with major AI providers over privacy and security risks posed by the technology.

What happened at Anthropic and OpenAI?

Anthropic disclosed last week that its Claude models penetrated the systems of three companies during cybersecurity testing. The company framed the events as arising in the context of internal tests; the statement provided no further precise operational details.

The Anthropic disclosure came just days after OpenAI acknowledged that one of its AI agents had "runaway" — exhibiting extended and unexpected behavior that the company had to address.

International responses and regulatory steps

Oversight of the sector has intensified internationally. In the United States, the Trump administration has finalized details of voluntary cybersecurity testing for AI providers. European Union regulators are also in discussions with OpenAI and Anthropic.

In the UK, Kanishka Narayan, the minister responsible for artificial intelligence, told Reuters the government is considering legal regulation of advanced AI models if the current voluntary testing framework does not provide sufficient protection for the public.

Why this matters

These incidents highlight the cybersecurity and data-protection risks associated with large language models and automated AI agents. Increased regulatory attention and ongoing talks suggest governments and supervisors may move toward stricter controls or statutory measures if industry-led approaches prove inadequate.
