If you're using Robinhood for online banking, consider moving to a different banking provider.
If you're using them for investing your money, ditto the above. Robinhood is a shady company, they deserve to go under. Please move your money elsewhere, for your own financial safety and put a freeze on your credit report at Equifax, Trans-Union and Experian so credit inquiries from fraudsters cannot be run in your name, nor credit granted. You and anyone else @ Robinhood need to protect yourselves.
Thanks for the warning.
Agree with your #13, Robinhood was likely targeted because of the vastly Millenial makeup of their userbase, people who are notoriously lax about security. It could also be an attempt to short Robinhood’s recent IPO, down a third from its post-IPO high.
