Robinhood stock fell nearly 3% in after-hours trading Monday.<\/b>
\nRobinhood Markets on Monday afternoon disclosed an unauthorized party obtained access to personal information for nearly one-quarter of the company’s nearly 20 million users, marking one of the biggest security breaches ever for the popular online brokerage. Shares of Robinhood fell as much as 3% to $37 in after-hours trading, reversing a 2.6% increase on Monday. Though the security breach on Wednesday marks one of Robinhood’s largest ever, it’s certainly not the first. Hackers reportedly infiltrated nearly 2,000 accounts and siphoned off customer funds in a breach last October. At the time, a spokesperson said the cybercriminals targeted users whose personal email addresses had been compromised outside of Robinhood and therefore did not stem from a beach of its internal systems.
