Inside the $400 million Coinbase breach: An Indian call center and teenage hacke

Coinbase disclosed on May 15 that criminals stole personal data from tens of thousands of customers, an incident it says could cost up to $400 million. The hackers allegedly bribed overseas customer support agents employed by TaskUs, a New Braunfels, Texas company that provides Coinbase with customer service staff in Indore, India. Coinbase says the stolen data covered over 69,000 customers and was used by fake agents in social engineering scams, and it has put a $20 million bounty on those responsible. A Fortune investigation, based on messages with a self-described hacker, suggests the attack was carried out by a loose network of young English-speaking hackers known as "the Comm."
