In the hacking incident that the SUI network was subjected to, the hacker began transferring a large portion of the stolen funds to Ethereum. In the image, we see a series of transfers made in less than an hour, where he purchased large amounts of ETH worth approximately 60 million dollars.
The transfers were made through protocols like CoW Protocol and Wombat, tools typically used to facilitate trades in a way that does not reveal the user's identity. This means that the hacker is trying to hide the trail of the funds and transfer them to secure wallets or perhaps to liquidate them later.
