David Schwartz, CTO Emeritus of Ripple, issued a public warning about an active phishing campaign targeting Robinhood users. The statement was shared on his social media accounts along with screenshots of a fraudulent email he personally received, which simulated an official security notification from the platform.
What sets this scheme apart from typical fraud is its level of sophistication: according to Schwartz, the malicious messages appear to have been sent through Robinhood’s own notification system, making them virtually indistinguishable from legitimate communications. The email included login data, device information and a prompt to review account changes, all elements characteristic of a genuine security alert.
WARNING: Any emails you get that appear to be from Robinhood (and may actually be from their email system) are phishing attempts.

Schwartz noted that early evidence suggests the attackers found a way to inject malicious content into Robinhood’s notification system, ruling out for now the hypothesis of a direct hack of the company’s infrastructure. The community reacted with concern, questioning how a platform of that size allowed its official email system to be compromised. The executive did not confirm a definitive response on the matter, though his warning was clear: even emails that appear completely legitimate should not be considered trustworthy at this time.
