The Shibarium cross-chain bridge suffered a "sophisticated" flash loan attack on Friday. The attacker borrowed 4.6 million BONE tokens and allegedly temporarily gained control of 10 of the 12 validator keys, gaining majority validation rights. The attacker then transferred approximately 224.57 ETH and 92.6 billion SHIB tokens, equivalent to approximately $2.4 million, from the bridge contract. The attacker also obtained approximately $700,000 worth of KNINE tokens, but was unable to sell them after the address was blocked by the K9 Finance DAO. (The Block)
