The Chinese cyberespionage group TA419 has been targeting U.S. AI policy experts through credential phishing campaigns. These attacks, documented by Proofpoint, involved impersonating a former White House OSTP official and prominent economists to gain access to sensitive accounts. The phishing tactics employed included the use of Microsoft AitM (Adversary-in-the-Middle) techniques, allowing attackers to intercept credentials even with multifactor authentication. The campaigns, which began in July 2026, aimed to compromise experts at think tanks and universities, providing strategic insights into regulatory frameworks and technological competition between the U.S. and China. The operation reflects a shift in TA419's focus towards high-value targets within the AI policy domain, indicating a growing interest in influencing AI governance and research. Current status indicates ongoing threats as the group continues to refine its tactics.
