Hacker Sends The Final key of Multichain Accounts to PolyNetwork

In Brief:

  • Poly Network was hit by a major hack this month wherein the hacker stole more than $600 million worth of tokens.
  • The hacker has finally given Poly Network access to the final tranche of stolen funds.

Hacker Sends The Final key of Multichain Accounts to PolyNetwork using an Ethereum transaction. In the Message inside the transaction, the hacker also apologies to the Poly Network Team.

“I have to admit that my wild or mad behaviors have led to crises to your project, your team and even your lives. Sorry for the inconvenience! It must be one of the most wild adventures in our lives.”

The key provided by Hacker is: d3c0196b81dba3c2811c0a39536e4dc47d640e3099a9331821d40fd1d6ab66fb

In a message embedded in a digital currency transaction, the hacker said they were ”(quitting) the show.”

“My actions, which may be considered weird, are my efforts to contribute to the security of the Poly project in my personal style,” he said.

The hacker ends the message with “YOUR CHIEF SECURITY ADVISOR”, Implying they have accepted the PolyNetworks job offer.

“The consensus was reached in a painful and obscure way, but it works. Some people even suspect that the whole story is a PR stunt.”

An anonymous attacker stole $612 million in bitcoin from the Poly Network cross-chain DeFi protocol earlier this month. Later, through the messages on the Ethereum blockchain, a lot of things about the hacker came forward. He disclosed that he did it “for fun”. He also added that he “wanted to highlight the weakness” before others could exploit it. Later, in a strange twist, the hacker got ready to return all the assets.

Poly Networks Response

Poly Network, in a Twitter post, confirmed that the hacker has granted access to the final portion of stolen funds. The hacker gave back nearly all of the money except $33 million of frozen tether or USDT. The firm said that it has been in conversation with Tether to unfreeze these assets.

Dear "Hacker",

Thank You! We are ready for a new journey.

Poly Network Teamhttps://t.co/djwsVJRXrN

— Poly Network (@PolyNetwork2) August 23, 2021

In a blog post on Monday, PolyNetwork confirmed that the “white hat” shared the private key needed to regain control of the remaining assets. 

“At this point, all the user assets that were transferred out during the incident have been fully recovered,” Poly Network said. “We are in the process of returning full asset control to users as swiftly as possible.”

Poly Network said its team “confirmed that the private key is genuine.”

“As of now, Poly Network has regained control of the $610 million in assets that were overall affected in this attack. Once again, we would like to thank Mr. White Hat for keeping his promise, as well as the community, partners, and the multiple security agencies for their assistance.”

The hack has been one of the most strange stories about cryptocurrencies more recently. The theft was thought to be the biggest crypto heist of all time
