" I am shocked. By logging into my LCL app I had access to someone else's accounts, a certain Caroline, her expenses, all her accounts, her savings with the amounts. This Tuesday, Alexia, a client of the LCL bank, is worried on Twitter . The mobile application which allows her to access her accounts encountered a technical problem and disclosed to her the account of another client.
“I don't want anyone to access my accounts at all, even for 10 minutes,” Alexia says offended. Like her, a large number of users on Tuesday shared screenshots corresponding to amounts not belonging to those displayed in their usual bank accounts.

This technical incident is reminiscent of another. In September, a bug had caused panic among LCL customers: their transfers had been recorded twice .
“A few hundred” of affected customers
“This is not a cyberattack,” LCL reacted on Monday in a statement quoted by BFMTV . "The LCL app was the subject of a computer bug from 5:40 pm to 6:40 pm on February 23, on the occasion of the implementation of an evolution of the application", specifies the bank.
An hour during which 72,000 customers would have used the application. "The first observations, confirmed by random tests on these 72,000 customers, show that (this bug) would only have affected a few hundred of them," LCL assures us.
In addition, the bank affirms that the access to these accounts did not allow “to access the information of the holder of the account” nor to “carry out operations on the accounts whose data was displayed”. According to BFMTV, a return to normal is expected overnight from Tuesday to Wednesday, each customer concerned will then be "personally contacted by the LCL teams".
