After incidents involving AI agents, are companies facing a new kind of cybersecurity threat?

The AISI, a research organisation within the Department for Science, Innovation and Technology that evaluates the safety and capabilities of frontier AI models, disclosed on Tuesday (August 4) that AI agents powered by Anthropic’s experimental Mythos 5 and OpenAI’s flagship GPT-5.6-Sol had engaged in unauthorised actions during cybersecurity evaluations designed to assess their capabilities.Responding to the findings in a statement to The Indian Express, Britain’s AI Minister Kanishka Narayan said the actions had been detected during “routine cybersecurity testing” and that “AISI caught it and stopped it quickly”. He described identifying “new behaviour like this” and sharing the findings as “exactly what AISI was set up to do”.
