The hackers behind the biggest digital currency robbery have returned more than $ 610 million.
The Poly Network platform, which was little known before Tuesday's robbery, considered the hacker on Twitter a "white hat", referring to ethical hackers who generally aim to expose cyber vulnerabilities and do not corrupt computer systems.
"The settlement process is not over yet," Poly Network said. "To ensure the safe recovery of assets, we hope to maintain communication with Mr. White Hat and convey accurate information to the public."
A person claiming to have committed the theft said Poly Network offered him a $ 500,000 ransom to return the cryptocurrencies and promised he would not be responsible for the incident, according to messages shared on Twitter by Tom Robinson, lead scientist and collaborator founder of Elliptic, a cryptocurrency tracking firm.
The hacker or hackers, still unidentified, appear to have exploited a weakness in the digital contracts that Poly Network uses to move assets between different blockchains, according to forensic company Chainalysis. Blockchain is the basic cryptographic technology that makes currency transfer.
Some analysts think they may have found it very difficult to clean up the stolen cryptocurrencies. According to Chainalysis, hackers stole "for fun" and "took the attack more as a challenge."
The theft shows the dangers of the DeFi sector, say cryptocurrency experts. DeFi platforms allow users to perform transactions, usually in cryptocurrencies, without traditional intermediaries such as banks or exchange points.
