Taiko Ethereum Layer 2 Network Halts After $1.7M Bridge Exploit

Taiko, an Ethereum Layer 2 rollup, has halted block production following a security breach affecting its bridge mechanism. An attacker exploited a flaw in the bridge's message-proof verification, allowing them to forge withdrawal requests without legitimate deposits. The estimated losses amount to $1.7 million, with 1.99 million Taiko tokens transferred to the MEXC exchange. Taiko has urged users to withdraw funds from all bridges and requested centralized exchanges to suspend deposits of its native token. The incident was initially reported by Blockaid, which identified the root cause as an exposed signing key on GitHub. The team is coordinating with its Security Council and ecosystem partners to contain the incident and prepare a post-mortem report. The breach highlights vulnerabilities in cross-chain bridges, which have been targeted in multiple exploits this year.

Key Points: • Taiko halted block production after a $1.7 million exploit of its bridge mechanism. • The attacker forged withdrawal requests due to a flaw in message-proof verification. • Taiko has advised users to withdraw funds and suspended token deposits on exchanges.
