The US has linked North Korea-backed hackers to a massive cryptocurrency heist worth $615m (£469m) from players of the popular online game Axie Infinity last month.

Axar.az informs that players can earn crypto through game play or trading their avatars.

The hack is likely one of the biggest ever to hit the crypto world.

US officials say they linked the breach to a group called "Lazarus", believed to be controlled by North Korea's primary intelligence bureau.

"Through our investigations we were able to confirm Lazarus Group and APT38, cyber actors associated with [North Korea], are responsible for the theft," the FBI said in a statement on Thursday.

Lazarus Group gained notoriety in 2014 after they were accused of hacking into Sony Pictures and publicly leaking confidential data.
