Vulnerabilities in the Lightning Network are already exploited by hackers

Lightning Labs CTO Olaoluwa Osuntokun and ACINQ reported that recently discovered vulnerabilities in the Lightning Network are being exploited by cybercriminals.

Late last month, Australian programmer and Lightning Network developer Rusty Russell announced the discovery of vulnerabilities that could lead to loss of user funds.

The developers said they had already discovered “confirmed cases of exploiting vulnerabilities in the work environment.” So, vulnerabilities were used to steal bitcoins, although at the moment the number of victims and how much cryptocurrency was stolen is not known.

Osuntokun emphasized that a large number of Lightning Network nodes are vulnerable and encouraged their owners to upgrade as quickly as possible. It is reported that vulnerabilities are affected by nodes running LND programs version 0.7 and lower, c-lightning version 0.7 and below, and eclair nodes prior to version 0.3.1.

Lightning Labs also emphasized that the project is still at an early stage of development and mistakes are inevitable, so users should not list funds that they cannot afford to lose through the Lightning Network.
