Meta blocks Iranian plot to impersonate Americans with AI

Meta revealed it had shut down an Iranian-backed network of Facebook and Instagram accounts that leveraged artificial intelligence to impersonate Americans online. The operation, identified by Meta, involved four Facebook pages and 31 Instagram accounts, amassed a following of 79,400 users. The accounts posted content echoing anti-Republican sentiment, messaging on the Israel-Palestine conflict, and immigration issues.

Operators behind the fake profiles portrayed themselves as U.S. citizens, including activists, students, and graphic designers from major U.S. cities. They targeted high-profile political figures, journalists, and news outlets with requests for content collaborations, though none materialized. Meta attributed the use of AI-generated content to the inauthentic accounts, a tactic increasingly common in online influence operations.

The campaign, described by Meta as having a "moderate" reach, managed to generate meaningful but limited engagement. To evade detection, the actors used proxy and hosting services in the U.S. and Canada, masking their Iranian origins. Meta is investing in AI technologies to detect and remove such inauthentic accounts more swiftly. This incident underscores the growing role of AI in foreign disinformation efforts.
