The cyber attack targeting the Lithuanian-based bank, which has almost 2 million Irish customers, occurred earlier this month with between 30,000 and 50,000 customers impacted globally.
Revolut confirmed the news in a statement to the Irish Mirror but refused to confirm whether or not any Irish customers were directly affected.
"Revolut recently experienced a highly targeted cyber attack. This resulted in an unauthorised third party obtaining access to the details of a small percentage (0.16%) of our customers for a short period of time," a spokesperson said.
"We immediately identified and isolated the attack to effectively limit its impact and have contacted those customers affected. Customers who have not received an email have not been impacted," they added.
Revolut also insisted that "no funds have been accessed or stolen."
"Our customers’ money is safe - as it has always been. All customers can continue to use their cards and accounts as normal.
"We take incidents such as these incredibly seriously, and we would like to sincerely apologise to any customers who have been affected by this incident as the safety of our customers and their data is our top priority at Revolut," the spokesperson added.
The incident happened late on the night of Sunday, September 11, with officials for the bank saying they quickly "identified and isolated" the attack by the next day, drastically limiting its impact.
Revolut continues to investigate the hack and is working with regulators. They have asked customers affected to be vigilant. They are not required to take any other action and did not lose any of their deposits.
