Coinbase, a major cryptocurrency exchange, was targeted in a cyberattack with potential losses between $180 million to $400 million.
The attack involved criminals bribing overseas employees to obtain internal documents and sensitive data of certain customer accounts.
Although passwords and user funds were not impacted, a ransom demand of $20 million was made, which Coinbase refused to pay.
Coinbase is now offering a $20 million bounty for information on the hackers, amidst increased scrutiny and challenges faced by the cryptocurrency industry.
