Crypto Exchange HTX Hit by $258 Million Outflow After Hack

Following a significant hack, the HTX crypto exchange, associated with industry figure Justin Sun, experienced a net outflow of $258 million between its November 25 reopening and December 10. Data from DefiLlama indicates that this outflow signals unease among clients after the security incident in the previous month. HTX, acknowledging a $30 million loss in crypto tokens during the breach, temporarily halted withdrawals and deposits in response to the attack.

Crypto investors have been moving their assets away from crypto exchange HTX (formerly Huobi) following a Nov. 22 exploit that saw the exchange pause its services and lose $30 million. 

Between Nov. 25 — the day that HTX resumed its services — and Dec. 10, the exchange had some $258 million in net outflows, according to data from DefiLlama.

DefiLlama data shows HTX’s reserves comprise 32.3% Bitcoin (BTC) and 31.8% Tron (TRX). TRX is the native currency of the Tron network, a blockchain launched by Sun in 2017. 

At the time of publication, HTX is the 16th largest crypto exchange by daily trading volume, with a total of $1.6 billion in trading volume in the last 24 hours, per CoinMarketCap data. 

Following HTX’s restart on Nov. 25, Sun promised any affected HTX users that they would be fully compensated for the hot wallet losses and said a probe was underway.

Over the past two months, HTX and other Sun-linked entities, such as crypto exchange Poloniex and the HTX Eco Chain (HECO) bridge, have been hacked four times. 

The first HTX hack occurred less than two weeks after the exchange rebranded itself to HTX, with an unknown attacker stealing nearly $8 million in crypto on Sept. 24, 2023.

The largest of the exploits was the $100 million Poloniex exchange exploit on Nov. 10, allegedly caused by a private key compromise.

HTX’s HECO Chain bridge — a tool designed for moving digital assets between HTX and other blockchain networks — also suffered a massive breach on Nov. 22. Hackers compromised HECO and sent at least $86.6 million to suspicious addresses.

Meanwhile, November was the worst month for crypto theft in 2023, with hackers and other malicious actors making off with $363 million of ill-gotten digital assets.
