Cryptocurrency exchange HTX (formerly Huobi) returned 5,000 ETH (~$7.9 million at that time) stolen at the end of September for a hacker reward of 250 ETH (~$409,000).
We have confirmed that the hacker has fully returned all funds, as promised, and we have also paid the hack a white hat bonus of 250 ETH. The hacker made the right choice. We would like to express our gratitude to everyone in the industry for their help! https://t.co/SwY49A25h2

Tron founder Justin Sun, who sits on HTX’s advisory board, said the hacker “made the right choice.”
“We would like to express our gratitude to everyone in the industry for their help! Strengthening blockchain security and protecting user assets has never been an easy task, and we are working tirelessly,” he added.
The white hat hacker warned about the nature of the exploit in an on-chain message. According to him, the hack was made possible due to the leak of keys from the exchange’s hot wallet. He advised changing the address and reducing the frequency of its use.
ForkLog previously reported that on September 23, an unknown person hacked the cloud service provider Mixin Network and withdrew about $200 million in digital assets.
According to Immunefi, in the third quarter, industry losses from hacking and fraud reached $685.5 million – 59.9% more than in the same period last year.
Let us recall that in April, an attacker who hacked the Euler Finance DeFi protocol returned almost all the stolen funds. In total, the hacker withdrew $196 million worth of cryptocurrency from the platform.
In the same month, an attacker who attacked the Sentiment liquidity protocol sent back 90% of the assets. He took advantage of a re-entry error on the platform and stole about $1 million in digital assets.
