A fraudster used a real government agency email domain to trick Revolut into handing over passport copies, selfies, and full Bitcoin transaction histories for some users.
Crypto Security & Data Breach News
Revolut handed sensitive customer data to a fraudster after being deceived by a fake government request. The attacker sent data requests using an unauthorized email account on a legitimate government agency's official domain. Those requests passed Revolut's authentication checks. The company later determined they were not genuine.
High-Net-Worth Users Appear To Have Been Targeted
Revolut said it contacted affected customers directly. Some customers reported receiving notification emails on Sept. 12. The company said its systems and customer funds were unaffected. It declined to disclose how many customers were hit, which country they were in, or which government agency was impersonated.
Former Mt. Gox CEO Mark Karpelès said he was among those affected. He shared Revolut's customer notification publicly. On-chain investigator ZachXBT also alerted followers to the breach on X. He wrote that the incident appeared to target high-net-worth users, a concern given the recent rise in physical attacks on known crypto holders.
The breach drew swift criticism on social media around Know Your Customer (KYC) rules. Marc Zeller wrote that he had woken up to find all his data leaked. He added that the episode was "a sharp reminder that KYC hasn't produced meaningful upside and has put many in harm's way." Several other users echoed similar concerns about mandatory identity data collection creating risk without protection.

Revolut also began rolling out EURR, its euro-backed stablecoin, to customers in Denmark, Poland, and Portugal in August 2026. The company serves 80 million customers globally. It is also weighing an IPO. The breach adds to a pattern of data security incidents hitting crypto and fintech firms in recent months.
Hardware wallet maker Trezor disclosed last week that a breach at shipping provider ShipMonk affected roughly 67,000 US customers. That substantially expanded a case Trezor first reported in August 2026. Trezor also separately disclosed that attackers used a third-party email provider breach to send phishing emails from its legitimate domain, an approach similar to how Revolut's attacker exploited a trusted domain. Crypto wallet provider SafePal disclosed that a flaw in an order-tracking system had exposed data belonging to approximately 39,798 customers.
