Chinese hackers impersonated AI experts to target US policy minds

What the report says

Cybersecurity firm Proofpoint says a China-aligned hacking group known as TA419 has been posing as artificial intelligence experts to reach US policy figures. In a report released Thursday and reported by Al Jazeera with Reuters, the campaign was described as having started in April 2025 and intensifying in July, when the group allegedly used the names of real people to make messages appear legitimate.

According to the report, the hackers targeted policy experts at think tanks, universities, defence contractors and law firms in the United States and Japan. The approach reportedly began with seemingly routine outreach, including invitations such as requests to join an “AI Policy Advisory Committee,” and then moved victims toward fake sign-in pages designed to steal account credentials. Proofpoint said the attackers also used browser pop-up tricks inside otherwise normal webpages to make the login prompt look authentic.

The article says one impersonated figure was Lynne Edwards Parker, a former senior White House technology official. Reuters was able to confirm that at least one target was Alex Engler, a former White House official who now leads the Penn Center on Media, Technology, and Democracy; he said he received the message and later realized it was fraudulent. Al Jazeera also noted that the same group previously impersonated an Anthropic employee in February. The report matters because it suggests policy communities around AI remain a high-value target for cyber-espionage and credential theft.
