BTCPay urges Bitcoin merchants to replace wallets after hackers steal an estimated $1.6 million

BTCPay Server has urged merchants to rebuild outdated payment servers and replace wallets after attackers stole Bitcoin and Litecoin . In a Nov. 2 security advisory , the open-source Bitcoin payment software provider warned that installing the latest update may not protect funds if hackers have already gained access to a server. The warning follows a series of attacks targeting installations running version 2.4.1 or earlier, using a different method to exploit a vulnerability that BTCPay patched on Aug. 7. Blockchain analytics firm Bitquery traced approximately $1.63 million in suspected thefts involving 18.38 BTC and 3,405 LTC across 682 wallet sweeps between Oct. 30 and Nov. 2. Its investigation found that 87% of the funds moved during an eight-hour window on Nov.
