Cyber criminals bribed and recruited a group of rogue overseas support agents to steal Coinbase customer data to facilitate social engineering attacks. These insiders abused their access to customer support systems to steal the account data for a small subset of customers.

We now know that "small subset" was nearly 70,000 people. Coinbase wrote in that same blog post that it received a ransom note extorting the company for $20 million, which it did not pay. Instead, the company said, it established a "$20 million reward fund for information leading to the arrest and conviction of the criminals responsible for this attack."
