[Litecoin Discloses Zero-Day Vulnerability Leading to DoS Attacks and Abnormal MWEB Transactions, Issue Resolved] According to Golden Finance, on April 26, Litecoin disclosed via the X platform that a recent zero-day vulnerability had caused DoS attacks, primarily affecting major mining pools. Mining nodes that were not updated in time allowed an invalid MWEB (MimbleWimble Extension Block) transaction to be executed, enabling the associated tokens to be extracted to third-party DEXs. The Litecoin network rolled back these invalid transactions through a 13-block reorganization (reorg), ensuring they would not be included in the main chain. All valid transactions during this period were unaffected. The vulnerability has now been fully resolved, and the network has returned to normal operation.
