Shibarium releases a security update: specific bridge operations have been restricted, and a limit has been placed on short-term BONE token staking by attackers.

Golden Finance reported that the Shibarium cross-chain bridge connecting the Layer 2 network Shibarium with Ethereum was attacked by a flash loan attack this week, resulting in the theft of approximately $2.4 million in ETH and SHIB. Shibarium has now released a security update, which states:

1. Specific bridging operations have been restricted to prevent new unauthorized transactions;
2. Upgrade and restrict potentially exploitable paths (deposit/withdrawal/claims/rewards), and increase targeted defensive controls to prevent abuse of delegated staking;
3. Restore and protect the BONE held by the staking manager at risk; the attacker's short-term BONE staking will be subject to intervention and effective restrictions of the protocol mechanism.
4. Rotate validator signers, migrate contract control to multi-party hardware custody; continue extensive migration from legacy keys;
5. Monitor attacker traffic in real time; automatically alert partners and exchanges and report.
6. Hire independent security researchers, incident response companies, and relevant departments.
