Greek Police Dismantle AI Voice-Cloning Fraud Ring

Greek authorities dismantled a criminal organization that used artificial intelligence to clone the voices of victims' relatives during phone scams. The Directorate Against Organized Crime arrested two men, aged 23 and 25, in Nea Ionia, Attica, as they collected jewelry worth €30,000 from a victim's home.

The group operated with a structured hierarchy since at least July 2026, featuring "callers" who identified targets and "collectors" who retrieved valuables. Callers posed as employees of the power grid operator DEDDIE, mobile providers, or fiber-optic companies to trick victims into handing over money or goods.

“They cloned the voice of a relative of the victim to enhance the persuasiveness of the fake scenario.”

When victims expressed doubt, the fraudsters urged them to call a relative for reassurance. The gang then obtained that relative's phone number, called them pretending to be a telecom representative, recorded a voice sample, and used AI tools to clone it. They then called the victim again, playing the cloned voice to confirm the fake scenario.

Police have verified at least six fraud cases using this method. The confirmed proceeds exceed €120,000, but investigators estimate the total haul surpasses €1 million. A case file has been opened against six individuals for criminal organization, fraud, and aggravated theft; three suspects besides the two arrestees have been identified.
