The Copay wallet from U.S.-based bitcoin payments processor BitPay has been compromised by a hacker, the firm says.
Bitpay announced Monday that it learned about the issue from a Copay GitHub report indicating that a third-party JavaScript library used by the apps had been modified to load malicious code.
The malware was deployed on versions 5.0.2 through 5.1.0 of its Copay and BitPay wallet apps, and could potentially be used to capture private keys to steal bitcoin and bitcoin cash.
