Outdated BTCPay Server instances face hot-wallet theft

BTCPay Server’s maintainer urged users to install the latest version after hackers drained hot-wallet funds from outdated instances, BleepingComputer reports. The report does not say how attackers reached the servers or identify affected versions.

The loss is direct: a BTCPay instance connected to a hot wallet can put spendable cryptocurrency at risk, not just interrupt payment processing. The reporting does not establish whether upgrading closes a route attackers already used.

For operators whose BTCPay servers connect to hot wallets, updating alone cannot show whether an already-targeted instance is clean or whether funds were lost; the report provides no incident-response details.
