BTCPay Server identified an attack targeting instances running version 2.4.1 or earlier after receiving reports of unauthorized Bitcoin and Litecoin payments, BleepingComputer reported. The payment processor's maintainer urged operators to update to version 2.4.7 and recommended taking instances running 2.4.1 or older offline as soon as possible. The project began receiving theft reports on Sunday evening UTC and asked hosting providers to take affected instances offline. Its investigation confirmed an attack path involving versions earlier than 2.4.2, distinct from the recently disclosed vulnerability that prompted the 2.4.7 emergency release. BTCPay said it had no credible reports of hot wallet drains on the latest version.
