An AI Fraud Kingpin's Confessions

Yuriy Nazarenko says OnlyFake began as a way to automate the painstaking work of digitally forging identity documents. Before building the site, he spent hours editing passport scans by hand, adjusting photographs, machine-readable codes, and document details so they could pass human and automated checks. OnlyFake combined templates with generative AI to produce realistic images of fake passports, driver’s licenses, and other documents - including pictures that made the IDs appear to have been photographed on a table or carpet. For a few dollars’ worth of Bitcoin, customers could generate documents at scale, potentially using them to open bank or cryptocurrency accounts, incorporate companies, or conceal their identities.

The site exposed a serious weakness in know-your-customer systems: convincing fake document images could let criminals bypass checks designed to establish who customers really were. Nazarenko says the project grew beyond his understanding of its consequences, spawning copycats and attracting law-enforcement attention. Authorities arrested him, and he pleaded guilty; prosecutors said OnlyFake earned more than $1 million by selling IDs for about $15 each. Now free after a year in prison and living in Asia, he describes panicking when the site was first exposed, destroying devices and emails, and struggling with the pressures of running a growing fraud operation. He also says North Korean workers posing as IT professionals used the service. After completing his sentence, he spent months in immigration detention.
