Litecoin fixes a vulnerability in the MWEB privacy layer

ME News report, on April 26 (UTC+8), Litecoin said that a zero-day vulnerability appeared in the privacy layer of its MimbleWimble Extension Blocks (MWEB). The issue caused some non-upgraded nodes to validate invalid transactions and trigger a denial-of-service (DoS) attack against mining pools. The attacker exploited the vulnerability to move funds out to a third-party decentralized exchange (DEX). Subsequently, the network reorganized and rolled back the related invalid transactions by about 13 blocks, and normal transactions were not affected. The vulnerability has since been patched and the network has resumed normal operation. (Source: MLion)
