Financial services firm Robinhood Markets says an attacker has gained access to its customer support system, stolen account details for 7 million people and then attempted to extort the company.
Robinhood, which is based in Menlo Park, California, offers commission-free trading of stock, funds and cryptocurrency.
The company, in a Monday blog post, says the attacker tricked a customer support employee over the phone on Wednesday, which led to the attacker gaining “access to certain customer support systems.”
The attacker obtained email addresses for 5 million people and full names for a “different group” of 2 million people, Robinhood says.
