Nearly 2000 Robinhood accounts hacked

Nearly 2000 accounts of the trading app Robinhood have been hacked to an admission issued by them, downplaying the number as “limited”. The platform itself was not targeted directly.
Personal e-mails of the app users have been compromised and hackers gained access to the accounts through those e-mails.
Robinhood issued a statement:
“We always respond to customers reporting fraudulent or suspicious activity and work as quickly as possible to complete investigations. The security of Robinhood customer accounts is a top priority and something we take very seriously,"
The app also noted that users should enable two-factor authentication on their accounts and that when a customer notifies them of a otential breach on an account they restrict said account, investigate the unauthorized access, log the user out on all devices and request for a password reset.
Further reports, however, also note that some of the breached accounts did have two-factor authentication.

That last bit is very concerning - how did they manage to overcome the two-factor authentication?

Wow, this is very scary indeed. I wonder if there is a way they can shutdown the two-factor authentication or did they intercepted the generated codes as they are being sent to the clients' mobiles?

Thankfully, I do not use Robinhood. I hope no one here is affected, but if there are, I would be keen to hear his/her story. I am interested to know how Robinhood is going to do recovery for the affected accounts and what if the client is a substantial account. After all, I don't think the hackers would be keen to hack accounts that barely have much money.

Thanks for bringing this to our attention Mlawson71!
