Pando Rings hacker moves 4,000 ETH through Tornado Cash after 4 years – Details

The hacker behind the 2021 Pando Rings exploit on the Polygon-based lending protocol has moved 4,000 ETH through Tornado Cash, resuming activity after roughly four years of dormancy. The stolen funds, originally valued at approximately $53 million at the time of the attack, were funneled through the privacy mixer in multiple transactions, complicating on-chain tracing efforts. The move signals a renewed attempt to launder the proceeds, leaving investigators with fewer ways to follow the money. Pando Rings, which suffered one of the larger DeFi exploits of 2021, has since wound down operations. Market watchers should monitor for further mixer activity from the attacker's wallets and any potential movement of remaining stolen funds still held in linked addresses.
