Bitcoin exchange Bitfinex was hacked again, losing 119,756 BTC and has suspended trading

In the early morning of August 3rd, Beijing time, the popular Bitcoin exchange Bitfinex was attacked by hackers again. The website has now stopped trading and is working with law enforcement agencies to investigate the cause of the incident.

According to an announcement released by Bitfinex early this morning, the exchange stopped trading after discovering a security vulnerability. The statement posted on the official website said:

“We are investigating this vulnerability to determine what happened, but we are aware that some users’ Bitcoin funds have been stolen. We are conducting a review to determine which users were affected by this vulnerability. While we investigate and protect the trading environment, bitfinex.com will be temporarily unavailable and replaced with maintenance pages.”

[...] Any solution will be based on the market price at 18:00 UTC. We are taking the necessary accounting steps to restore the account balances of operational targets. After the investigation, we will select a solution to address customer losses. Although we will stop all operations during this period, we can confirm that this vulnerability only affects Bitcoin wallets, and other digital tokens traded on Bitfinex are not affected.

As of press time, Bitfinex's trading page is no longer accessible. Users can check Bitfinex's status update page. 8btc will follow up on the progress of this incident.

In June, the exchange was offline for a long time due to data center problems, but has since resumed operations. They were also fined $75,000 by the CFTC for illegal over-the-counter financial transactions.

It is reported that Bitfinex is one of the most active platforms in the market, with a daily trading volume of more than 40,000 BTC.

Update: Bitfinex CEO Zanetackett has confirmed that a total of 119,756 BTC, worth approximately $62 million, was lost.
