Shibarium has announced a series of security measures following a flash loan attack on its cross-chain bridge, which resulted in the theft of approximately $2.4 million in ETH and SHIB. The Layer 2 network has restricted specific bridge operations to prevent further unauthorized transactions and has upgraded its systems to limit potential abuse paths, including deposits, withdrawals, and staking rewards. In response to the attack, Shibarium has also taken steps to recover and protect at-risk BONE tokens held by staking managers, effectively restricting the attacker's short-term staking capabilities. Additional measures include rotating validator signers, migrating contract control to multi-party hardware custody, and enhancing real-time monitoring of attacker traffic. The network has also engaged independent security researchers and incident response firms to bolster its defenses.
