MILAN, Sept 25 (Reuters) – Fraudsters using AI to impersonate senior executives stole €95 million ($108 million) from Fideuram, the private banking arm of Italy’s biggest lender Intesa Sanpaolo, ​two sources familiar with the matter said on Friday.

More ‌than half the funds were later recovered, but some €36 million remains missing, the sources said.

The scheme, first reported by Corriere della Sera, began in February when then-Fideuram Chairman Paolo Molesini received what appeared to be a WhatsApp message ‌from ​Intesa Sanpaolo CEO Carlo Messina seeking urgent ⁠help with an overseas ⁠transaction.

The fraudsters followed up with a phone call that appeared to come from a senior partner at a prominent law firm, confirming the instruction. According to the sources, the callers used ​AI technology to replicate the lawyer’s voice.

Believing the request was genuine, Molesini instructed his finance department to arrange a series of ⁠transfers to foreign accounts, mainly in ⁠China and Hong Kong, the sources said.

Intesa Sanpaolo ​and Fideuram declined to comment.

Fideuram quickly detected irregularities in the transfers ​and alerted banks and authorities in several countries. Roughly €53 million ‌was later recovered through cooperation between authorities in China, Portugal and Italy, according to the sources.

The remaining funds have not been traced after passing through a network of overseas accounts and being ⁠converted into cryptocurrencies, they said.

Neither Molesini nor any other Fideuram executives are under investigation, the sources said. However, Milan prosecutors have placed a foreign ⁠national living outside ‌Europe under investigation on suspicion of computer fraud, ⁠one of the sources said.

Molesini resigned as chairman ​in ‌March citing personal reasons. At the time, Fideuram ​gave no ⁠further explanation for his departure.

Last year, fraudsters using AI to mimic the voice of an Italian minister persuaded businessman Massimo Moratti to transfer nearly €1 million to an overseas account. The money was later recovered.
