cross-chain protocol was confirmed by Twitter at 8pm yesterday, with the loss of $611 million, making it the largest DeFi hacking attack to date.

dwarf those at Japanese cryptocurrency exchange Mt.Gox, which were valued at about $430 million at the time. And the 58 billion yen XEM(worth about $524 million) lost on the Coincheck exchange in 2018.

We regret to announce that Poly Network has been attacked. Assets on the Binance, Ethereum, and Polygon chains have been transferred to the following hacker's address.

etheric currency: 0 xc8a65fadf0e0ddaf421f28feab69bf6e2e589963

BSC: 0x0D6e286A7cfD25E0c01fEe9756765D8033B32C71

Polygon:0x5dc3603C9D42Ff184153a8a9094a73d461663214

Notably with

, the hacker even initiated a transaction with himself, leaving a block message that said, "If I move my remaining SHITCOINS, it becomes a $1 billion hack!"

and

even said they weren't really interested in the money and were even considering returning some of it or leaving it there. According to IgorIgamberdiev, a researcher at TheBlock, who analyzed the cause of the attack, he pointed out that the root cause of the Poly Network attack was a cryptography problem, which may be similar to the Anyswap hacker incident. Hackers made off with $7.9 million after deriving the private key through a contractual loophole (rather than leaking it). Peckshield, the blockchain security team at

"Peckshield, first analyzed the course of events and noted that Poly Network was attacked, resulting in a total loss of about $611 million on bitonin, Ethereum and Polygon. According to Peckshield, $611 million was transferred to three separate addresses, with more than $272 million in stolen money at the Ethereum address beginning with 0xC8a6, more than $250 million at the BSC address beginning with 0x0D6e and more than $85 million at the Polygon address beginning with 0x5dc3.

"And so far, the hacker's Ethereum address has added liquidity to Curve containing about 673,000 DAI and 96.39 million USDCS. BSC addresses add liquidity on Ellipsis Finance containing about 32.1 million BUSDs and 87.6 million USdcs.

Poly Network also posted an open letter to the hacker on Twitter: "Our team would like to actively communicate with you and look forward to your return of funds. This is the biggest incident in DeFi's history, and you've committed a major economic crime under any country's laws. It would be very unwise of you to continue to transfer funds. And the money you stole is from tens of thousands of crypto community members, we hope you can take the initiative to negotiate with us.

Tether chief Technology Officer Paolo Ardoino tweeted that Tether has frozen Poly Network hacker addresses for $33 million USDT. Zhao Changpeng CZ, CEO of

"Has also noted that although no one controls BSC or ETH, we are working with our cSA team partners to help as proactively as possible.

OKEx executive Jay also said that OKEx has been monitoring the case, is watching the movement of tokens, and will do their best to assist in the matter. In addition, Tether's freeze of the stolen money was followed by an incident in which, according to Odaily, some people tried to share the scheme with hackers in exchange for a token handout, turning it into an instant begging scene. One of them, for example, warned the hacker to leave USDT alone because it was frozen, and was rewarded with 13.5ETH in return. Then a bunch of bored melon eaters turned to hackers for tips.
