The attackers sent a fraudulent request using a real government email address. Revolut complied and shared sensitive information including passport details, bank account numbers, home addresses, verification photos, identity cards, and Bitcoin activity records.
Once they had the data, the hackers began threatening to release it publicly unless the company paid a ransom. That demand has since been revealed as 10,000 Bitcoin, worth around $780 million at the time of reporting, based on a Bitcoin price of approximately $77,974.
What Data Was Taken
The stolen data reportedly includes transaction histories, account statements, verification selfies, and images of identity documents. Phone numbers and home addresses were also compromised.
Blockchain investigator ZachXBT said on Telegram that the attack appeared to target high-net-worth individuals. Screenshots shared online showed the attackers had already published data belonging to Felix Römer, CEO of online crypto casino Gamdom.
Mark Karpelès, former CEO of collapsed crypto exchange Mt Gox, was also among those affected. He received an alert from Revolut at 5:25 a.m. on September 12 warning that his data may be at risk. Karpelès said he does not believe Revolut should have shared the information regardless of whether the email appeared legitimate.
The attackers have accused Revolut of being negligent and of sharing customer data with countries outside its jurisdiction.
Revolut Responds and Regulators Step In
Revolut described the attack as a “sophisticated external impersonation scam.” The company said it blocked the offending email address as soon as it detected the issue.
The company also said it notified the relevant authorities and contacted all affected customers directly. Revolut reported itself to the UK’s Information Commissioner’s Office, which confirmed Monday it had opened an investigation.
The neobank has been working over the weekend to manage the fallout. It described the number of affected customers as “limited.”
The timing is difficult for Revolut. The company has been working toward a public offering valued at around $200 billion, far above its most recent private valuation of $75 billion.
A data breach of this scale, combined with a ransom demand and an ongoing regulatory investigation, adds pressure to those plans.
The attackers have reportedly said they will continue releasing customer data every day until the ransom is paid. No payment has been confirmed.
