Almost half a million Monzo customers affected by data breach
Monzo has urged its customers to change their personal identification numbers after admitting a data breach gave staff members access to their security information, reports Ruby Hinchliffe.
At least 480,000 British bank customers, a fifth of Monzo’s 2.6 million customer base, were affected by the data leak which allowed staff engineers access to PINs stored in encrypted log files.
The fintech challenger bank said it has finished deleting all the improperly stored information after discovering the error on Friday.
“No one outside Monzo had access to these pins. We’ve checked all the accounts that have been affected by this bug thoroughly, and confirmed the information hasn’t been used to commit fraud,” Monzo said in a statement yesterday.
The bank has emailed all customers affected by the breach, recommending that they change their PINs at a cash point and update their app.
