The Shiba Inu team revealed details of a recent hack on Shibarium, their Layer 2 network, which saw the attacker exploit a flash loan to acquire 4.6 million Bone ShibaSwap tokens. With these tokens, the attacker gained validator voting power and introduced malicious software to the network. The attack would not have been possible without the use of a flash loan, a type of uncollateralized loan common in blockchain transactions for arbitrage. The attacker returned the assets after draining them from the bridge, including 224.57 Ethereum. This incident underscores the vulnerabilities in DeFi ecosystems and the need for enhanced security measures.
