According to CNBC, on the evening of August 10, the cross-chain decentralized financial platform Poly Network was hacked, and more than $610 million worth of cryptocurrencies, including Ethereum, was stolen, which may be one of the largest thefts in the history of cryptocurrencies in the world to date.

A day later, the dramatic reversal stunned netizens, and the Poly Network issued an ultimatum to the hackers demanding the return of their assets and warning them that they would be hunted down by law enforcement agencies in various countries, but the hackers actually began to return some of the cryptocurrencies they stole.

As of 11:00 a.m. EST on Wednesday (23:00 Beijing time on Wednesday), about $258 million worth of cryptocurrency has been returned to the Poly Network address, but more than half of the assets have not been recovered.

In recent years, losses from cryptocurrency crime have soared. According to statistics, in the third quarter of 2021, there were 11 major security incidents in the distributed financial technology DeFi field in nearly one and a half months, and the amount of theft of Poly Network was the highest.

Yu Jianning, rotating chairman of the Blockchain Special Committee of the China Communications Industry Association, told reporters that hacker risk is one of the main risks of cryptocurrencies, and hackers often attack through vulnerabilities in smart contracts, such as lightning loan attacks and re-entry attacks. Cryptocurrency trading is prone to problems in asset interaction, asset locking, signature authorization, etc., resulting in asset loss.
