A data breach has been announced by Gnosis Pay, the company that provides white label stablecoin cards, affecting those cards.

The firm stated that on November 3, earlier this week, it detected “unauthorised access to the system powering Gnosis Pay-branded cards (our B2C business line), resulting in the exposure of certain customer information.”

The extent of exposed information varied by user. A Protos journalist was told that “your name as printed on your card, your shipping address and your Gnosis Pay account reference” were compromised.

Other individuals, such as Lefteris Karapetsas, reported that the email stated his compromised data contained his full home address, name, card number, and all wallet addresses associated with his account.

Gnosis Pay had previously planned to retire this system by the end of the year.

The breach at Gnosis Pay adds to a series of other cyber incidents—including hacks, attacks, heists, and breaches—that have hit the cryptocurrency space in recent months.

Protos contacted Gnosis Pay for a statement, but received no immediate reply.
