In September 2026, Greek law enforcement dismantled a criminal organization responsible for a sophisticated telephone scam operation that generated more than €1 million in illicit gains. The group leveraged AI voice cloning to impersonate victims' relatives, successfully deceiving private citizens through a coordinated multi-stage social engineering process.
What happened
The operation, which began at least as early as July 2026, utilized a structured hierarchy consisting of managers, callers, and collectors. Callers typically initiated contact by posing as employees from utilities, telecommunications companies, or service providers, often claiming the victim needed to undergo a technical procedure such as a fibre-optic installation.
When victims expressed skepticism, the perpetrators requested the contact information of a trusted relative or associate to verify the procedure. After obtaining the contact details, the scammers would call the trusted individual, posing as a service provider, to record a brief voice sample. Using AI tools, the organization created a high-fidelity clone of that person's voice. The scammers then called the original victim back, using the cloned voice to impersonate the trusted relative and confirm the legitimacy of the initial request. This tactic was designed to dispel doubts and facilitate the theft of money or valuables.
Police investigations led to the arrest of two individuals in Nea Ionia, Attica, who were caught acting as collectors while in possession of €30,000 worth of stolen valuables. The case file includes four additional identified suspects. Authorities have confirmed the gang's involvement in at least five similar incidents. During the operation, police seized two mobile phones and an operational vehicle that had been reported stolen on September 14, 2026. Following the arrests, the Hellenic Police issued a warning to the public, emphasizing that a familiar voice is no longer a reliable indicator of identity. They urged citizens to hang up on suspicious calls and independently verify claims by contacting relatives directly through known, trusted numbers.
