Millions in Stolen Cryptocurrency Being Laundered by KelpDAO Hackers

Following the $290 million KelpDAO heist, the perpetrators are now initiating the laundering process of their stolen cryptocurrency, as indicated by on-chain analyst ZachXBT and data from Arkham. According to Arkham, the primary wallet controlling the stolen funds executed two significant transactions on the Ethereum blockchain, totaling $117 million and $58 million, during European hours on Tuesday. ZachXBT observed that a portion of the stolen cryptocurrency has started to move across different blockchains, with approximately $1.5 million being transferred from Ethereum to Bitcoin via Thorchain, accompanied by an additional $78,000 routed through the Umbra privacy protocol - a tactic previously employed by North Korea's Lazarus Group. The utilization of cross-chain transfers and privacy tools during the initial 'layering' phase of money laundering suggests that the attacker is preparing to further distribute the funds across multiple platforms. The KelpDAO breach is among the most substantial DeFi security breaches in recent months, prompting widespread negative sentiment and fears of potential contagion across the DeFi sector. In response, Layer 2 network Arbitrum announced the freezing of $71 million in ether linked to the hack, potentially pressuring the perpetrator to expedite the movement and laundering of the remaining stolen funds.
