The person or group behind Ronin's exploit valued at $620 million that happened in March has apparently moved millions worth of Ether (ETH) through privacy protocol Tornado Cash in the past week, blockchain data from addresses connected to the exploiter show.

Tornado Cash enhances the privacy of transactions by breaking the on-chain link between a source and a destination address. This helps exploiters and hackers to mask their addresses while withdrawing gained funds.

The main wallet continues to hold upwards of 151,055 Ether, worth around $460 million at current prices.

Ronin was hit by a $620 million exploit back in March that affected Ronin validator nodes for Sky Mavis, the publisher of the popular Axie Infinity game, and the Axie DAO.
