Hackers stole more than $6 billion worth of cryptocurrency from Binance in 20 minutes. Binance has frozen assets worth $3 billion and pledged to cover all user losses. Binance said the security breach may have involved a compromised laptop and other attack vectors. Several cybersecurity firms said an elite hacking group from North Korea may be responsible. Cybersecurity expert Peter Tran said recovering the funds would be challenging because the stolen cryptocurrency can still be traded normally.
