Date: Oct 28, 2026
Amount: $783,100
Classification: Bridge & Cross-Chain
Technique: Cross-Chain Message Spoofing
An attacker exploited zkLink’s Arbitrator contract, which failed to clear a previously authenticated message hash after processing a claim. By reusing that hash through the publicly accessible SyncL2TxHashRelayer, the attacker impersonated an authorized gateway message and installed a malicious L2 logs root. The attacker then submitted forged withdrawal proofs against the compromised root to drain approximately $783,100 from zkLink’s Ethereum bridge
