While 20th-century heists involved scoping out a location, recruiting a person on the inside and having a daredevil getaway driver waiting outside, the 21st-century version looks more like what Bybit experienced today.

A major cryptocurrency exchange says it was the victim of a sophisticated hack that stole about $1.5 billion worth of digital currency, marking one of the biggest online thefts of all time

Ben Zhou, Bybit's CEO, said that the hack had affected around 401,000 Ethereum and sparked a surge in withdrawal requests.
