Criminal gang uses AI voice cloning for telephone fraud in Greece
A criminal organization in Greece used AI voice cloning to impersonate family members in telephone fraud schemes. Two members were arrested after stealing €30,000 from a victim, with the organization's total proceeds reportedly exceeding €1 million.
What happened
A criminal organization in Greece used AI voice cloning tools to impersonate family members of fraud victims via telephone. The gang posed as employees of utility companies (DEDDIE), mobile phone operators, fiber optic providers and other organizations.
Two members aged 23 and 25, acting as 'collectors', were arrested in Nea Ionia, Attica, after stealing valuables worth €30,000 from a victim's home. The organization had a structured hierarchy including leadership, 'telephone operators' who identified and contacted victims, and 'collectors' who retrieved stolen goods.
Reported impact
The organization's confirmed involvement spans at least five documented fraud cases using the same methodology. Additional theft of a vehicle on 14 September 2026 was attributed to the group, which used it as an 'operational vehicle'.
The estimated illegal proceeds from the organization exceeded €1,000,000. The immediate charges involve fraud and theft totaling more than €120,000.
Index analysis
The use of AI voice cloning to replicate family members' voices served to increase the credibility of the fraudulent pretext scenario and overcome victims' doubts about the caller's legitimacy.
Governance controls
Police issued public warnings advising citizens to immediately disconnect suspicious phone calls, not disclose personal or financial information, not rely on voice recognition alone as identity confirmation, and independently verify the caller by contacting known family members directly.
