Revolut security breach affects 50,000 customers

Hackers accessed the personal data of 50,000 Revolut customers this month, and a phishing campaign imitating the company soon followed, though the company did not confirm whether the events were linked.

As first reported by Bleeping Computer, Lithuania’s State Data Protection Inspector said in a Sept. 16 disclosure about the breach that the exposed data may have included names, addresses, emails, postal addresses and telephone numbers.

Revolut told customers on Sept. 15 about the breach, which reportedly happened on Sept. 11.

Lithuania’s inspector said Revolut had “taken prompt action to eliminate the attacker’s access to the company’s customer data and stop the incident.” The company also said it had reached out to customers affected by the breach and that customers who had not received an email were not affected.

The Lithuanian inspector said social engineering was behind the breach and that the company was still investigating.
