The world’s largest crypto-exchange platform says attackers used fake job interviews and malicious code to steal $US6.6 billion ($9 billion) in funds.

The attack on Binance, believed to be the largest cyber attack in the cryptocurrency sector’s history, caused the prices of most major cryptocurrencies to fall sharply.

The FBI has attributed the four-hour attack on October 29 to North Korea-affiliated hackers.

North Korea has denied the allegations, with the powerful sister of leader Kim Jong Un calling the claim “absurd rhetoric”.

How it unfolded

Binance said the hackers began their plans as early as June.
