Cash App data breach could have affected over 8 million users

(Gray News) – A data breach by a former employee of the company that owns mobile payment app Cash App could have affected more than 8 million users.

According to a report filed with the United States Securities and Exchange Commission, Block, Inc. announced that it determined that a former employee uploaded reports containing information about U.S. clients of its subsidiary Cash App Investing LLC in December 2021. .

Although the former employee had access to the information during his employment, the data was accessed without permission after he was no longer with the company, the filing said.

Only customers who used the Cash App’s stock feature are affected by the breach, according to the report. The information included full name and brokerage account number, brokerage portfolio value, brokerage portfolio holdings, and stock trading activity.

The data downloaded did not include usernames and passwords, social security numbers, dates of birth, payment card information, addresses, bank account information, or any other identifiable information.

Customers outside the United States were not affected, the filing said.

When he made the discovery, Block launched an investigation in partnership with a forensics firm. The company notified regulatory and law enforcement authorities of the breach.

The filing says the company “takes the security of information belonging to its customers very seriously and continues to review and strengthen administrative and technical safeguards to protect its customers’ information.”
