The Poly Network hacker has now returned $258 million to the cross-chain DeFi protocol, also noting that the attack could have been way bigger.
Announcing the massive hack, Poly Network tweeted, “We are sorry to announce that Poly Network was attacked,” explained that the hacker was able to access funds on various chains, moving them to three different wallet addresses.
The Poly Network, which steamed from the Neo project, allows the transfer of tokens between nine different blockchains. These include Bitcoin, Ethereum, Neo, Ontology, Elrond, Ziliqa, Binance Smart Chain, Switcheo, and Huobi ECO Chain.
The Poly development team had written to the hacker to cooperate with them by returning the stolen funds. But they got trolled.
The hacker, in a message, wrote: “It would have been a billion hack if I had moved [the] remaining sh**coins. Did I just save the project? Not so interested in money, now considering returning some tokens or just leaving them here.”
Described as the largest DeFi hack in history, Poly Network lost $612 million to the hackers on Aug. 10
In a chat with Forbes on Wednesday, Tom Robinson, the chief scientist at blockchain analytics firm Elliptic said the hacker has now returned.
Though the hacker says they’ll return the stolen funds on multiple occasions, building suggestions that it planned to teach Poly an expensive lesson about its security flaws, Robinson presented a contrary view.
According to hum, returning of funds “demonstrates that even if you can steal crypto-assets, laundering them and cashing out is extremely difficult due to the transparency of the blockchain.”
