Cybersecurity firm Proofpoint reported on Thursday that a Chinese hacking group, TA419, has been impersonating AI experts in the U.S., including Lynne Edwards Parker, to target policy experts since April 2025. The hackers sent emails posing as legitimate offers to join an "AI Policy Advisory Committee," leading targets to fake login pages designed to steal credentials. Victims included experts from think tanks, defense contractors, universities, and law firms in the U.S. and Japan; at least one confirmed victim is Alex Engler, a former White House official now at Penn’s Center on Media, Technology, and Democracy. Proofpoint warns that such impersonation tactics will likely continue targeting policy experts under the guise of real-world AI professionals.

Story summary
In July 2025, Chinese hackers operating under the group TA419 targeted US policy experts by impersonating prominent AI figures. These hackers used deceptive emails pretending to come from a former government official like Lynne Edwards Parker, inviting targets to join an "AI Policy Advisory Committee". Once engaged, victims were redirected to a fake login page designed to steal their credentials. The operation began in April 2025 and targeted individuals at think tanks and other policy organizations, posing significant risks to national security and data integrity.
