Kelp DAO Cross Chain Bridge Stolen $292 Million, Most of It laundered

In the April Kelp DAO cross chain bridge attack, approximately $292 million in assets were stolen. Except for the frozen approximately $710 million in ETH, the remaining approximately $220 million in funds have been laundered, leaving only about $1.7 million in assets at the attacker's original address. On chain analysis shows that attackers complete multiple rounds of cross chain and coin mixing operations through privacy tools such as THORChain, Wasabi, Tornado Cash, and Umbra. Hackers once split about 75700 ETH (worth approximately $175 million at the time) into multiple new addresses and crossed the chain to the Bitcoin network through THORChain, driving THORChain's daily trading volume to skyrocket to $394 million. The only asset that can currently be recovered is approximately 30800 ETH (approximately $710 million) frozen by the Arbitrarum Security Committee, but this portion of the funds has been embroiled in legal disputes.
