In an unlikely turn of events, the exploiter that stole over $600 million worth of funds from DeFi protocol Poly Network has now begun sending some of it back. So far, the hacker has returned $3.3 million in Ethereum, $256 million in Binance Smartchain, and $1 million in Polygon. Members of the crypto community on Twitter ($TWTR@US) speculated on several reasons as to why the hacker had an apparent change in heart. Some argued that blockchain Security firm Slowmist’s claims of identifying the hacker's IP and email information and linking its digital footprint to a Chinese crypto exchange Hoo had scared the hacker into cooperation. Polygon is trading at $1.33 Thursday morning.
