Jun 25, 2025·Paris, France French bank intern allegedly enables SIM-swapping fraud against 50 customers using stolen banking data
A French bank, Société Générale, was breached when an intern allegedly helped SIM-swapping scammers defraud 50 of its customers. The intern, a Master’s student working at the bank’s Paris headquarters, is accused of providing clients’ banking information to fraudsters, enabling them to steal over one million euros. Using the stolen data, scammers tricked mobile operators into transferring victims’ phone numbers to SIM cards under their control, allowing access to security codes sent by the bank. The fraudsters’ accomplices included a SIM swap specialist, a couple found with cash and luxury handbags, and a man suspected of creating fake IDs. The bank stated that victims were reimbursed, but questions remain about how the intern gained access to sensitive data and what internal safeguards were in place. Police raided Société Générale offices in Paris and Luxembourg, though it is unclear if the raids are related to this incident.
