Cash App Breach

In April, fintech giant Block, formerly known as Square, confirmed a data breach that exposed sensitive information of more than 8.2 million users. It involved a former employee who downloaded reports from Cash App that contained some U.S. customer information.

“I threw this one in more because of the value of the Cash App and the amount of personal data records,” Nachreiner said. “To some extent, these personally identifiable information (PII) breaches, you … get fatigue from hearing about them so much. But this is one I just picked because the Cash App itself is actually one of the more popular methods of payment. So if I were a customer, I certainly wouldn’t want my personal data out there. And 8.2 million records isn’t the biggest one ever.”
