Cash App, a popular stock trading app, has suffered a data breach impacting up to 8.2 million former and current users.
It has been reported that the breach was caused by a former employee illegitimately accessing customer information.
Block, Cash App’s owner, notified the Security and Exchange Commission (SEC) of the breach on Monday. The filing reported that a former employee downloaded investing reports containing information belonging to US customers, including full names, brokerage account numbers, brokerage portfolio values and holdings, and one day of stock trading activity.
“While this employee had regular access to these reports as part of their past job responsibilities, in this instance these reports were accessed without permission after their employment ended,” said a Cash App spokesperson in a statement to Mashable.
