Chinese hackers impersonated AI experts to target US policy minds

Chinese hackers have been impersonating artificial intelligence (AI) experts in the United States, including a former government official, according to a new report from cybersecurity firm Proofpoint.

The report, released on Thursday, found that in July, a China-aligned hacking group called TA419 targeted a slate of US policy experts by impersonating prominent figures, including Lynne Edwards Parker, the former principal deputy director of the White House Office of Science and Technology Policy.

The hackers, who had been operating since April 2025, first sent otherwise harmless-looking emails intended to engage a target, such as requests to join an “AI Policy Advisory Committee”, and, once they responded, the target would be sent to a fake login page designed to steal their credentials.

The targets included policy experts at think tanks, defence contractors, universities and law firms in both the US and Japan.

The report used a technique that creates a fake browser pop-up window inside a legitimate webpage that mimics an authentic-looking sign-in prompt to deceive victims and make it harder for them to realise they are handing over their information to hackers.
