Retool breach used SMS phishing plus an AI-cloned voice of a real IT employee
Retool · United States
Retool disclosed that on 27 August 2023 an attacker phished an employee by SMS and then called them using an AI-generated clone of a colleague's voice, obtaining a multifactor code.

Twenty-seven cloud customers, all in the cryptocurrency sector, had their accounts accessed.

Mandiant's investigation, published by 3CX on 20 April 2023, concluded the intrusion started when a 3CX employee downloaded and ran a trojanised installer for the X_TRADER trading application, itself the product of an earlier compromise of Trading Technologies' distribution site, on a personal computer.

French woman loses EUR 830,000 to an AI-image 'Brad Pitt' romance scam
Private individual in France (identified only as 'Anne') · France
Beginning in February 2023, a 53-year-old French woman known publicly as Anne was drawn into an online relationship with someone posing as actor Brad Pitt. Over about 18 months she sent EUR 830,000, largely after being told he needed money for kidney cancer treatment and that his accounts were frozen by divorce proceedings. AI-generated images of the actor in hospital and a forged passport reinforced the deception. She realised she had been defrauded on seeing genuine photographs of Pitt with his partner, and filed a police complaint; the case became public in January 2025 when French broadcaster TF1 aired and then withdrew her interview.
