Cyber hackers returned nearly half of the $600 million they stole from
Around $260 million has been returned as of Wednesday noon, Poly Network said in a tweet.
Of the funds given back, $3.3 million were in ethereum, $256 million in Binance smart chain, and $1 million in polygon, according to the post.
"The amount of money you hacked is the biggest in defi history," Poly Network said in a tweet Tuesday, adding that tens of thousands of people were negatively impacted.
The hackers responded on Wednesday, saying they were "ready to return" the funds they stole. It is unclear when they plan to return the whole sum.
Around $269 million on ethereum and $84 million on polygon remain with the hackers, according to the Poly Network tweet.
The hackers said they stole the funds "for fun :)" because "cross-chain hacking is hot," according to a Q&A session that was embedded in ethereum transactions sent from the account holding the stolen assets.
The screenshots of the exchange were obtained by Tom Robinson, cofounder of Elliptic, a blockchain analytics and compliance company.
"The Poly network is a decent system," the hackers said. "It's one of the most challenging attacks that a hacker can enjoy."
The hackers said they took the funds after spotting a bug "to keep it safe."
The cyberattack on Poly Network joins a growing number of attacks on the rapidly growing DeFi space.
Thus far, DeFi hacks made up over three-quarters of cryptocurrency money seizures this year, according to a report by intelligence firm Ciphertrace.
