The organizer of the attack on the Chinese Poly Network firewall protocol provided the key to the multisig wallet and returned the remaining $141 million of the stolen funds.
In a comment on the transaction, the hacker explained the delay in the final payment by blocking the stolen USDT in the amount of about $ 33 million. He added that Tether’s problem is excessive centralization.
The hacker also reported that he transferred to a multisig wallet a reward previously sent by the Poly Network team in the amount of 160 ETH (about $ 500,000) and donations he received from the crypto community. He asked the company to distribute these funds among the victims.
In general, the hacker called the incident “one of the craziest adventures in life” and signed himself “chief security adviser.”
Recall that on August 10, the Poly Network inter-network protocol was subjected to the largest attack on the Ethereum, Binance Smart Chain and Polygon blockchains in the history of the industry. The cumulative damage amounted to $611 million in various cryptocurrencies. Some of the stolen funds in USDT were blocked.
On August 11, the hacker announced his intention to return the funds. He transferred to the project team all the stolen assets with the exception of $33 million in USDT, which Tether froze after the attack. Part of the reimbursed funds was in a multisig wallet, the keys to which were controlled by both parties.
Earlier, the developers of Poly Network published a roadmap for the refund of funds and announced the launch of a bounty program to search for bugs in the main functions of the protocol.
