Woofun AI reports that Taiko released a review of the June 21 security incident on the Ethereum Layer 2 network. The team stated that attackers exploited leaked off-chain signature keys and bypassed verification mechanisms to forge proofs, circumventing the validator whitelist. The zero-knowledge proof system remained intact. Daily limits on fund bridges slowed capital outflows, while the security committee suspended bridge and vault operations within hours. Although approximately $1.75 million was stolen, over $11 million was protected. No users suffered losses, and all balances have been restored at a 1:1 ratio.
