Robinhood Estimates Hackers Infiltrated Almost 2,000 Accounts

An anonymous reader quotes a report from Bloomberg: Almost 2,000 Robinhood Markets accounts were compromised in a recent hacking spree that siphoned off customer funds, a sign that the attacks were more widespread than was previously known. A person with knowledge of an internal review, who asked not to be identified because the findings aren’t public, provided the estimated figure. When Bloomberg first reported on the hacking spree last week, the popular online brokerage disclosed few details. It said “a limited number” of customers had been struck by cyber-criminals who gained access by breaching personal email accounts outside of Robinhood, an assertion that some of the victims acknowledge and others reject.

The attacks unleashed a torrent of complaints on social media, where investors recounted futile attempts to call the brokerage, which doesn’t have a customer service phone number. Robinhood, which has more than 13 million customer accounts, is now considering whether to add a phone number along with other tools, the person said. This week, Robinhood sent push notifications to users suggesting they enable two-factor authentication on their accounts. It also plans to send customers more advice on security, according to the statement. Several victims said they found no sign of criminals compromising their email accounts. And some said their brokerage accounts were accessed even though they had set up two-factor authentication.
