Popular US equities and crypto currency trading platform Robinhood Markets has revealed that it suffered a major data breach. Hackers gained access to the personal detailss of 7 million customers and are now have demanding a ransom payment.

An unauthorised third party “socially engineered a customer support employee by phone,” Robinhood said, and was able to access its customer support systems. 

“Late in the evening of November 3, we experienced a data security incident. An unauthorised third party obtained access to a limited amount of personal information for a portion of our customers.  A threat actor supposedly gained access to vital systems after calling in to a Robinhood customer support employee and using social engineering to gain access to data. “Based on our investigation, the attack has been contained and we believe that no Social Security numbers, bank account numbers, or debit card numbers were exposed and that there has been no financial loss to any customers as a result of the incident, “ the Robinhood said in a blog.

The unauthorised access allowed the cyber criminals to obtain a list of email addresses for about 5 million customers and full names for another group of about 2 million people. For a limited number of people, about 310 in total, the information compromised included their names, date of birth and ZIP code. Furthermore, 10 customers had “more extensive account details revealed”, the firm said.

Based on its investigation, Robinhood believes no bank account details, social security numbers or debit card numbers were exposed. Customers have seen no financial loss as a result of the breach, it claimed adding that the hackers have demanded an ransome payment.

The California-based company has said that it immediately informed law enforcement, but has not said if it paid any ransom to hackers and is investigating the breach with the help of cyber security experts from FireEye / Mandiant.

Robinhood offers a popular mobile app for trading crypto currency, stocks, and more. More than 22 million users have accounts at Robinhood, of which nearly 19 million users actively used the platform during September 2021, according to the company. “As a Safety First company, we owe it to our customers to be transparent and act with integrity…  Following a diligent review, putting the entire Robinhood community on notice of this incident now is the right thing to do.” Robinhood’s said CSO Caleb Sima.

The data breach is thought to be the largest suffered by Robinhood, although not the first. In 2020, cyber criminals stole customer funds after infiltrating nearly 2,000 accounts at Robinhood. That time Robinhood said the attack did not arise from a beach of its internal systems but as a result of hackers targeting  customers whose email addresses had already been compromised independently of Robinhood.
