Litecoin suffered a network disruption caused by a zero-day vulnerability, but resolved the issue through a chain reorganization.
On April 25, Litecoin said on its official X account that a denial-of-service, or DoS, attack stemming from a zero-day bug affected some major mining pools. The vulnerability appeared in mining nodes that had not been updated and allowed invalid MimbleWimble Extension Block, or MWEB, transactions to be confirmed.
The problematic transactions involved moving coins to an external decentralized exchange, or DEX. In response, Litecoin carried out a 13-block chain reorganization and voided all abnormal transactions that occurred during that period.
The affected transactions were not included in the main chain, and normal transactions during that period were not impacted, the network said.
The vulnerability has been patched and the network is operating normally.
