These groups, which include Russian military intelligence and Iran's Revolutionary Guard, are using advanced AI to produce realistic responses and improve their hacking techniques.

To counter this, Microsoft has imposed a comprehensive ban preventing state-backed hackers from accessing their AI products. Tom Burt, Microsoft's VP for Customer Security, emphasized the company's commitment to prevent known threat actors from leveraging their AI technologies, regardless of legal or terms of service infringements.

Responses from implicated nations varied, with Russia, North Korea and Iran not immediately commenting, while a Chinese spokesperson denied allegations and promoted the responsible use of AI.

This revelation adds to growing concerns about the misuse of AI technology. OpenAI's cybersecurity expert, Bob Rotsted, noted that this is a rare public acknowledgment from an AI company regarding the use of AI by cyber threat actors.

The report details different uses of AI by the hacker groups, including Russian operatives investigating military technologies for Ukraine operations, North Koreans creating content for spear-phishing attacks, Iranians crafting convincing fake emails, and Chinese hackers collecting intelligence information.

The extent of account suspensions and the scale of the activity remains undisclosed. However, Microsoft stands firm on its zero-tolerance policy against hacking groups using AI, citing the potential risks and unprecedented power of the technology.
