The Litecoin network recently faced a significant block reorganization due to a zero-day vulnerability that was exploited by attackers. On April 25, this vulnerability allowed for a DoS attack, which disrupted major mining pools and affected nodes running outdated software. These nodes validated invalid transactions within the MimbleWimble Extension Block privacy layer, enabling perpetrators to send invalid coins to third-party DEX platforms. In response, developers executed a 13-block reorganization to reverse the false transactions and secure the network. Litecoin representatives assured that all valid operations remained intact and the bug was fully resolved. Alex Shevchenko, CEO of Aurora Labs, described the event as a coordinated attack, affecting blocks #3,095,930 to #3,095,943. Despite the attack, the price of Litecoin showed minimal impact, trading at approximately $56 with a slight 0.5% decrease.
