Crypto debit card provider Gnosis Pay has disclosed a data breach affecting customers of its legacy card system. The Block reported on November 6 that unauthorized access was detected on November 3 in the system that powers Gnosis Pay-branded debit cards. According to the company’s statement as relayed by The Block, certain customer information was exposed, but customer funds were not affected.
Gnosis Pay said it contained the incident within two hours, replaced compromised security credentials and addressed the vulnerability. The enterprise platform behind its white-label card programs was not affected. The company has not disclosed how many users were hit, and the vendor involved was not named. CryptoTicker noted that Gnosis Pay describes the data only as “certain customer information” and that affected customers were emailed with specifics, which have not been published.
The legacy system is due to be retired on December 20, and the company has made 3D Secure verification mandatory for online card payments until then. CryptoTicker reported that Gnosis Pay advises customers to treat unexpected emails, texts and calls with suspicion, to rely only on official apps, and to arrange a replacement card and move subscriptions before the shutdown. The company says it will never ask for a seed phrase, private keys, PIN or full card number.
The Block placed the incident among other recent card-related breaches in crypto, including one at Based, where an attacker accessed an internal dashboard on October 5, and a Revolut case involving a fraudulent government-domain request.
