PANews reported on September 21st that the Shibarium cross-chain bridge, which connects the Layer 2 network Shibarium and Ethereum, was previously attacked by a flash loan, with approximately $2.4 million in ETH and SHIB stolen. Shibarium has now released a security incident update, stating: 1. Specific bridge operations have been restricted to prevent new unauthorized transactions; 2. Upgrade and restrict potential abuse paths (deposits/withdrawals/claims/rewards) and add targeted defensive controls to prevent abuse of delegated staking; 3. Recover and protect the at-risk BONE held by the staking managers. The attacker’s short-term BONE staking will be effectively restricted by intervention and protocol mechanisms. 4. Rotate validator signers and migrate contract control to multi-party hardware custody; continue the broad migration away from legacy keys; 5. Real-time monitoring of attacker traffic; automatic alerts and reporting to partners and exchanges; 6. Hire independent security researchers, incident response firms, and relevant departments.PANews reported on September 21st that the Shibarium cross-chain bridge, which connects the Layer 2 network Shibarium and Ethereum, was previously attacked by a flash loan, with approximately $2.4 million in ETH and SHIB stolen.
