BTCPay alert: disable servers due to hot wallet vulnerability
BTCPay, Bitcoin payment software widely used by merchants, issued an alert asking users to shut down their servers immediately. Attacks were reported against versions 2.4.1 and earlier, just days after the company launched an emergency fix for a critical flaw. This is an important reminder about the security of hot wallets in production environments. Merchants using BTCPay should update to the latest version and review their security practices. The vulnerability specifically affects hot wallet functionality, which keeps private keys on the server to process payments automatically. For those operating a BTCPay node or accepting Bitcoin as payment, it is essential to keep up with security alerts and apply patches quickly. This type of incident reinforces why many merchants prefer to use remote signing models or Lightning Network to reduce private key exposure. https://decrypt.co/382324/btcpay-tells-merchants-to-switch-off-servers-amid-h…
