Bitcoin Node Operators Warned of Urgent Security Update After Attack Targeting Unpatched Nodes

Operators of unpatched Bitcoin nodes are being targeted by attackers, according to Core Lightning. The team behind the open-source node software for the Bitcoin Lightning Network urged operators to upgrade immediately if they're running version 26.06.7 or earlier.

The urgent security update comes after reports of potential vulnerabilities were received. Core Lightning did not specify which vulnerabilities were being targeted or the potential impact.

In September, Core Lightning released version 26.06.8, which delivered bug fixes and patches for 'vulnerabilities responsibly reported by a number of sources'. The release notes credit the Bitcoin Red Team and 12 other named individuals and groups, along with anonymous reporters.
