The threat actor who hacked Poly Network's cross-chain interoperability protocol yesterday to steal over $600 million worth of cryptocurrency assets is now returning the stolen funds.
As the Chinese decentralized finance platform Poly Network shared two hours ago, the hacker has already returned almost $260 million worth of stolen cryptocurrency.
To send back all the stolen funds, the hacker still has to return another $269 million on Ethereum and $84 million on Polygon.
The threat actor explained the motivation for the hack by embedding Q&A messages in transactions, the motives behind their decision to give back the stolen cryptocurrency are not yet known.
In a weird twist of events, Poly Network also urged the hacker to return the cryptocurrency stolen from "Thousands of crypto community members" to avoid landing on law enforcement's radar.
OKEx, Tether, and Huobi also added that their security teams were working on freezing cryptocurrency assets identified as stolen in the attack.
