Cybersecurity experts have long warned of the persistent and patient threat from North Korea's long-running hacks. The world's largest crypto exchange was still caught off-guard.

The cryptocurrency exchange said it's now covered 95% of the stolen assets.

Hackers working for North Korea are suspected of hacking a Binance employee's laptop, which allowed the theft of billions in crypto.

Some estimates say hackers stole billions in crypto from Binance, the world's largest cryptocurrency exchange, during a cyberattack on Thursday.
