According to Bloomberg, major cryptocurrency exchange Binance has suffered another hack. This time the hackers withdrew 7,000 Bitcoin, which values approximately $40 million USD. This is the second major breach the exchange has faced, the first being an incident in March 2018.
Via a post on its website, the exchange said that the hack occurred through a single transaction in a “large scale security breach.”
It furthered that the hackers used a “variety of techniques” including phishing and viruses to gather large quantities of user data. The exchange also warned that there may be additional accounts that are yet unaccounted for but have been affected.
Detailing the hack, Binance said:
“The transaction is structured in a way that passed our existing security checks. It was unfortunate that we were not able to block this withdrawal before it was executed. Once executed, the withdrawal triggered various alarms in our system. We stopped all withdrawals immediately after that.”
The hack was isolated to one wallet—Binance’s BTC hot wallet—which holds 2% of the company’s entire Bitcoin holding. It furthered that all other wallets are secure and unharmed.
The post went on to say the following:
“The hackers had the patience to wait, and execute well-orchestrated actions through multiple seemingly independent accounts at the most opportune time […] We must conduct a thorough security review. The security review will include all parts of our systems and data.”
Binance Hack Security Review
This security review will take about a week, during which all deposits and withdrawals are suspended. Trading remains active, however, to allow investors to change their positions.
As the news is fresh, the company is still unsure whether or not the hackers still control some accounts and could “use those to influence prices in the meantime.” Traders will be fully covered and no user funds affected, as Binance will use its emergency insurance fund called the Secure Asset Fund for Users.
Bitcoin dropped 3% in early morning trade upon the news. It has since pared those losses, however, and is currently up 0.17%, selling for $5,937 USD.
