Jinse Finance reports that the Shibarium cross-chain bridge connecting the Layer 2 network Shibarium with Ethereum was attacked by flash loans this week, resulting in the theft of about $2.4 million in ETH and SHIB. Currently, Shibarium has released a security update, which states: 1. Specific bridging operations have been restricted to prevent new unauthorized transactions; 2. Upgrade and restrict potentially abused paths (deposit/withdrawal/claim/rewards), and add targeted defensive controls to prevent the abuse of delegated staking; 3. Restore and protect BONE at risk held by staking managers, with short-term BONE staking by attackers being effectively intervened and limited by protocol mechanisms; 4. Rotate validator signers, migrating contract control to longer hardware custody; continue extensive migration from legacy keys; 5. Monitor attacker traffic in real time; automatically alert and report to partners and exchanges; 6. Hire independent security researchers, incident response companies, and relevant departments.
