Anthropic and other researchers have revealed that thousands of individuals were victims of catfishing on dating scam apps. These fraudulent applications utilized LLM-generated replies, specifically from models like Claude, to deceive users. Security researcher Matthew "Zigula" Gore-Kormanik discovered this while investigating a dating app named Dora, where he encountered a pop-up indicating a call from "Jennifer."

This report is among the first to detail how LLMs like Claude are being actively exploited in large-scale dating scams, moving beyond theoretical misuse to documented real-world impact.
