Cryptocurrency exchange Poloniex, which recently suffered a $126 million hack, managed to identify the hacker. The hacker has the opportunity to return the stolen crypto assets for a reward until November 25.

Over the weekend, Poloniex owner Justin Sun, who founded the Tron crypto project, sent $0.10 in ether to the attackers’ addresses, telling the hackers that they had been identified. Law enforcement agencies of Russia, China and the United States were involved in the investigation. Messages attached to transactions indicate that all stolen crypto assets are marked so that thieves will not be able to use them. Justin Sun warned that the accounts of individuals or entities that attempt to make transactions with the hacker will be blocked.

On November 10, Poloniex suffered a major hack, during which the attacker managed to withdraw $56 million in ETH, $48 million in TRX, and $18 million in BTC from the exchange. After the incident, the exchange disabled the hot wallet for maintenance and began an investigation. Poloniex management promised to compensate all affected users.

At first, Justin Sun offered hackers a 5% reward for returning stolen assets. A few days later, the exchange increased the reward for the hacker to $10 million. However, the Tron founder warned that his offer would only be valid until November 25, after which law enforcement would begin an operation to detain the hackers.

Let us recall that in September the HTX cryptocurrency exchange, formerly called Huobi, where Justin Sun holds the position of advisor, suffered from a hack. The hacker stole 5,000 ether worth $8 million from HTX, but later returned the funds to the exchange, receiving a reward of 250 ETH.
