The hacker who hacked the Poly Network firewall protocol worth $611 million on August 10 threatened to postpone the end of the refund until at least next week.
A day after the successful attack, the hacker declared his readiness to return the assets and offered to create multisig wallets for this. The keys to them are controlled by both sides.
As of August 12, the hacker transferred stolen funds to the project in the Binance Smart Chain and Polygon networks — $253 million and $85 million, as well as all assets on the Ethereum blockchain. The exception was the amount of $33 million in USDT, the address of which was blocked by the issuer of the stablecoin, the company Tether
Your essays are very convincing, but in fact one feels distrust.
“What a fun game. You don’t even think about unblocking my USDT account. I am not ready to publish the key this week,” the hacker wrote in the signature to the Ethereum transaction on August 18.
This was a response to a message from the Poly team, which assured the hacker that it was doing everything possible to remove the Tether lock and was counting on a “speedy result”.
“We still hope that you will be able to provide us with the key this week, because thousands of users are waiting for their assets to be returned,” they added.
The team also transferred 160 ETH to the hacker, which approximately corresponds to the amount of the $500,000 reward offered to him earlier. The hacker refused it.
Earlier, experts suggested that one of the reasons for the refund was that the hacker lit up personal data.
He himself said that he hacked the Poly Network “for fun.”
