Litecoin Patches Vulnerability After 13-Block Chain Disruption

Litecoin has patched a critical vulnerability after a suspected zero-day exploit triggered a 13-block chain reorganization, raising fresh concerns around blockchain security and network resilience.

According to developers, the exploit launched a denial-of-service attack against updated mining pools, temporarily suppressing their hashing power and allowing invalid transactions to enter Litecoin’s MimbleWimble Extension Blocks privacy layer.

Once updated nodes regained control, the network reorganized and removed those transactions from the main chain. While the vulnerability has now been fully patched, analysts suggest the timing indicates attackers may have known about the flaw in advance.

The incident adds to growing concerns around low-hashrate proof-of-work chains, especially as cross-chain bridges and privacy layers become more complex attack surfaces. For markets, security remains one of crypto’s biggest infrastructure risks despite technological maturity.
