Litecoin Experiences 13-Block Reorganization After Double-Spending Attack

Litecoin encountered a significant disruption following a double-spending attack that resulted in a 13-block reorganization. According to NS3.AI, the attack exploited a consensus bug within Litecoin's MWEB privacy extension, allowing the attacker to mint invalid coins and sell Litecoin (LTC) before patched miners rejected the compromised chain. Although the reorganization affected 32 minutes of transactions, it took the network nearly three hours in real time to replace the impacted blocks.
