The hacker behind what is thought to be the biggest-ever hack of a decentralized finance project has begun returning the stolen funds from the hacking.
Cross-chain protocol Poly Network was robbed of $612 million in more than a dozen cryptocurrencies on August 10 in what it described as the exploit of “a vulnerability between contract calls.”
But in a $0 Ethereum transaction at 3:48 a.m. UTC on August 11, the hacker embedded a very welcome message: “READY TO RETURN THE FUND!” 
The hacker followed that up with another transaction message reading, “IT'S ALREADY A LEGEND TO WIN SO MUCH FORTUNE. IT WILL BE AN ETERNAL LEGEND TO SAVE THE WORLD. I MADE THE DECISION, NO MORE DAO.”
After asking for a multisig wallet address, the hacker began returning some of the loot at 8:46 a.m. UTC.
As of 11:47 a.m. UTC, Poly Network that received more than $4.7 million back, it tweeted

Just Ask Nicely

That happened after Poly Network reached out to the hacker several times on Twitter, urging the return of the funds.

Aside from pointing out that law enforcement agencies around the world would likely pursue what they “will regard as a major economic crime,” Poly Network also pointed out that “[t]he money you stole are from tens of thousands of crypto community members, hence the people.”

The funds had been stolen from Poly Network’s  Ethereum ($247 million), Binance Smart Chain ($254 million), and Polygon ($85 million) wallets. 

While not on this scale, the DeFi sector has seen a blitz of hacks and exploits as it exploded onto the crypto scene in the last few years. 

Blockchain research firm Messari reported in April that DeFi protocols had been robbed of $284 million since 2019. Among the largest DeFi hacks was the April 19 theft of more than $120 million from EasyFi.
