Synthetic ID fraud surges 8x as AI fuels deception

A new LexisNexis Risk Solutions analysis warns that synthetic identity fraud has surged to become the fastest-growing fraud category globally, now constituting 11% of all reported cases and signaling a dangerous shift toward generative AI-assisted deception, according to Biometric Update.

The firm's Cybercrime Report, which examined 116 billion online transactions, documented an eight-fold spike in this specific methodology during 2025, as fraudsters increasingly blend stolen personal data fragments to fabricate credible, long-con identities that evade conventional biometric and deepfake defenses. While synthetic schemes accelerate, first-party fraud, where customers exploit their own legitimate credentials to dispute charges or default on obligations, remains the dominant threat at thirty-eight percent of incidents, followed by traditional account takeover attacks.

Stephen Topliss, vice president of fraud and identity at LexisNexis, cautioned that "cybercriminals are experimenting with the same technologies" transforming commerce, pointing to a staggering 450 percent increase in automated agent traffic used for payments and logins. The convergence of malicious bots and legitimate AI agents is blurring the line between genuine and fraudulent activity, compelling organizations to rapidly advance their ability to discern intent, not just identity, in an increasingly automated digital ecosystem.
