Notice for Poly Network Hack

DeFi’s interoperable cross-chain protocol has been robbed of more than $600 million. Intrusion analysis revealed that private keys had been compromised. It was facilitated by errors in the design of the intelligent Network Poly contract.

Poly Network said at the time that the hacker had removed assets from Ethereum, Binance Smart Chain, and Polygon. Blockchain data shows that it is approximately $273 million from Etherea. Also, $253 million from the BSC and $85 million from the Polygon network in USD Coin (USDC).

According to reports shared by Elliptic and Chainalysis, which track cryptocurrencies, the person who claims to have hacked said he did it “for fun”. He wanted to “detect a vulnerability” before others could exploit it, and planned return of the tokens.

According to reports, Elliptic co-founder Tom Robinson said the decision to return the loot could be caused by problems washing the stolen cryptocurrency on such a scale. He stated:

“Even if you successfully steal the cryptocurrency, its laundering and monetization are extremely difficult. This thanks to the transparency of blockchain and the wide use of blockchain analysis by financial institutions.”

On August 10, the Poly team released an open letter to the perpetrator calling on him to return the stolen assets. Mainly because “law enforcement authorities in any country will consider it a serious economic crime. You will be prosecuted.”

The target of the attack was a long list of DeFi protocols, most of which ran on BSC. These include PancakeBunny, Cream Finance, bEarn, Bogged Finance, Uranium Finance, Meerkat Finance, SafeMoon, Spartan Protocol, Belt Finance, and Impossible Finance.
