Coinmama, an Israeli crypto brokerage which allows users to purchase Bitcoin and Ethereum with credit cards, has suffered a major data breach. According to a February 15 company announcement, around 450,000 of its users have been affected by the hack.
Reports have shown that Coinmama’s security breach is part of a huge, multi-platform hack that affected 24 different companies and over 747 million records. Multiple gaming, travel booking, and streaming websites were also affected.
Coinmama says a list of around “450,000 email addresses and hashed passwords” of users who registered on its platform before August 5, 2017, have been posted on a dark web registry.
However, the company said that there has been no evidence of this data being used by perpetrators and, given the nature of the published data, there’s no reason to suspect any other Coinmama systems are compromised.
A response team now requires all potentially affected users to reset their passwords upon login and is currently monitoring its array of systems for suspicious activity or unauthorized access.
