More than 8 million users of the Cash App mobile payment service could be affected by a data breach involving a former employee who took records containing customer names and account numbers.
Although the usernames and passwords of the account were not affected, the mobile payment application now notifies customers of the breach, it revealed in a presentation on April 4 to the Securities and Exchange Commission . Cash App is owned by Block, formerly known as Square, a financial payments company run by Twitter co-founder Jack Dorsey.
Block told the presentation that it “recently determined that a former employee downloaded certain reports” belonging to Cash App. This information included full user names and brokerage account numbers, a unique identifier for a person’s stock activity in Cash App Investing. For some clients, the compromised data also included “the value of the brokerage portfolio, the holdings of the brokerage portfolio and / or the stock trading activity during a trading day,” according to Block.
“While this employee had regular access to these reports as part of his or her previous work responsibilities, in this case these reports were accessed without permission after the completion of his or her job,” the company said.
According to the file, no personally identifiable information was taken. Usernames, passwords, Social Security numbers, dates of birth, and access codes were not affected, Block said. The default only affected U.S. customers.
