Two cryptocurrency platforms linked to well-known digital entrepreneur Justin Sun have been hacked in two attacks and around $115 million may have been stolen so far. HTX digital currency exchange, formerly known as Huobi, said in a statement on Wednesday that it had also been targeted, with hackers withdrawing about $30 million worth of cryptocurrency.

HTX also confirmed that the so-called blockchain bridge HecoChain was also attacked.

Justin Sun, an investor in HTX and associated with HecoChain, confirmed that the above-mentioned theft did indeed occur.

Blockchain bridges connect different networks, allowing for the fast exchange and movement of various cryptocurrencies. It turns out that these chains are vulnerable to hackers.

According to the assessment of market analysis company CryptoQuant, the total value of cryptocurrencies stolen by hackers from the Heco chain so far is approximately US$85.4 million, mainly stable coins USDT and Ethereum.

A large amount of HTX’s native cryptocurrency, HBTC, was also stolen. According to data from CoinGecko, the price of HBTC is down more than 5% compared to 24 hours ago.

It is also reported that Justin Sun said that HTX will fully compensate for the losses of HTX hot wallet, and deposits and withdrawals are currently suspended.

He said: "All HTX funds are safe, please rest assured the community. We are investigating the specific cause of the hacker attack. Once we complete the investigation and identify the cause, we will restore services."
