If you run your own node on the Lightning Network using the Alby Hub software, you have had one concrete job since September 9, 2026: check the version number. If it reads anything between v1.7.0 and v1.18.5, and the management interface is reachable from the open internet, an attacker can gain unauthorised access and drain funds, according to the provider. Which puts the answer to the central question right at the top: check the version, close off access from the internet, update to v1.24.0, and change the unlock password afterwards.
