Final episode of the series – The PolyNetwork hacker, dubbed “Mr. White Hat,” has finally returned the remaining funds he siphoned off. A gesture that signs the end of a rocky adventure, which could have turned into a nightmare for the decentralized finance protocol (DeFi)
A promise made, a promise kept
The PolyNetwork protocol hack has been the subject of much ink in the crypto media, particularly following
in cryptocurrencies he had stolen. The protocol team then rushed to create 3 addresses to receive the returned funds.
in a tweet on August 23 that the return of the remaining $141 million has been made. The hacker has therefore returned the 28,800 ethers and 1,000 WBTC still in his possession. PolyNetwork publication – Source: Twitter
PolyNetwork will now be able to give back to its users the total control of the assets that were stolen:
“The team has confirmed that the private key is genuine and functional. As of now, Poly-Network has regained control of the $610 million (not including the $33 million USDT frozen) in assets that were globally affected by this attack.”
Hacker amply rewarded
The story has a “happy ending” for PolyNetwork, which has publicly thanked the hacker for his gesture:
“Once encore, we would like to thank Mr. White Hat for keeping his promise as well as the community, partners and multiple security agencies for their help.
As a reminder, Mr. White Hat had exploited a vulnerability in Poly-Network’s smart contract, quietly siphoning off the $610 million he just returned today.
This time, PolyNetwork was lucky. Even so, DeFi needs to make more of an effort on the security front, as the sector has a poor track record, according to the CipherTrace report released this August 2021.
