Litecoin gives post-attack update, but other devs doubt zero-day theory

Litecoin experienced a "zero-day" vulnerability leading to a 13-block reorganization of its blockchain. The bug caused a denial of service attack on mining pools, allowing older nodes to post invalid transactions. While the Litecoin team claims the bug has been patched, some developers doubt it was a zero-day exploit, suggesting prior knowledge of the vulnerability. The incident highlights the increasing risks associated with cross-chain bridges in the crypto space, which have been frequent targets for attacks.
