Bitcoin (BTC) deposits and withdrawals have resumed on the Justin Sun-associated cryptocurrency exchange HTX, previously known as Huobi, following a significant security breach on November 22, which led to a loss of $30 million.
HTX announced in a blog post on November 26 that it had restored deposit and withdrawal services for several major cryptocurrencies, including Bitcoin (BTC), Ethereum (ETH), Tron (TRX), and Tether (USDT). Justin Sun later shared on X (formerly known as Twitter) that HTX is working on reinstating full functionality for the remaining cryptocurrencies, anticipating completion by the following week.
This incident marks the fourth major security breach in two months affecting platforms linked to or controlled by Justin Sun. On the same day as the HTX exploit, the HTX Eco Chain (HECO Chain) — which includes HTX, Tron, and BitTorrent, all associated with Sun — was compromised, resulting in a loss of $86.6 million.
Additionally, the Sun-owned crypto exchange Poloniex experienced a significant security breach on November 10, with an estimated $100 million in assets stolen. Blockchain security firm CertiK suggested that this attack was likely due to a compromise of a private key.
These series of attacks began shortly after Huobi rebranded to HTX, with an initial theft of nearly $8 million in cryptocurrencies from the exchange’s hot wallet on September 24. These incidents highlight ongoing security challenges in the cryptocurrency exchange sector, particularly concerning hot wallets and other vulnerable points in exchange infrastructure.
