Coinbase

Coinbase, a cryptocurrency exchange with over 100 million customers, has disclosed that cybercriminals working with rogue support agents stole customer data and demanded a $20 million ransom not to publish the stolen information.

The company said it would not pay the ransom but would establish a $20 million reward fund for any leads that could help find the attackers who coordinated this attack.

The disclosure comes after the criminals behind the breach emailed Coinbase on May 11, demanding a $20 million ransom to prevent public disclosure of stolen information about certain customer accounts and internal documentation.
