As Bitcoin Lighting Network users await details regarding a security vulnerability found on the network late last month, developers are now warning that the vulnerability has been exploited. According to Olaoluwa Osuntokun, CTO at Lightning Labs, and ACINQ, a Lighting Network development firm, there are “confirmed instances of the vulnerability being exploited in the wild.”
Users are advised to upgrade the following affected Lightning Node versions:
– LND nodes version 0.7 and below
– c-lightning nodes version 0.7 and below
– eclair nodes version 0.3 and below
On August 30, 2019, Rusty Russell, an Australian software programmer and Bitcoin Lightning coder, tweeted out a warning that security issues had been discovered on the Lightning Network that could cause various projects to lose funds. The Lightning Network is an experimental second-layer scaling solution built on top of the Bitcoin Network for quicker fund transfers.
