The hacker responsible for Poly Network’s $600 million exploit has expressed his willingness to return the stolen cryptocurrency assets in an embedded Ethereum transaction message on 11 August.
In a follow up message, the hacker stated he had failed to contact Poly Network’s team, and was requesting a multi signature wallet to return the stolen funds to. Poly Network wasted no time in posting three separate wallet address — for Binance Smart Chain, Ethereum, and Polygon — on its Twitter account.
Several hours after the addresses were posted, Poly Network confirmed it had already received more than 1 million ISDC on Polygon, and encouraged the hacker by saying he was “moving things to the right direction”. An hour after that, the hacker also returned around $1.1 million in BTCB on Binance Smart Chain, and later an additional $2.6 million worth of tokens to the Ethereum address.
When Poly Network revealed it had suffered an attack yesterday, it became known the hacker was able to steal around $600 million in tokens from the three blockchains the protocol was operating on. According to blog post from security company SlowMist, the individual took advantage of a bug in Poly Network’s cross-chain smart contracts.
