The brokerage account numbers are unique identifiers linked to a customer's stock activity on Cash App Investing. Reports also had data on one trading day's brokerage portfolio value, brokerage portfolio holdings, and stock trade activity. Block stated in the filing that the employee "had regular access to these reports as part of their past job responsibilities." The problem is that they re-obtained access to these highly sensitive reports after their employment came to an end. The reports did not contain any additional personal information. This includes usernames or passwords, Social Security numbers, birthdates, payment card information, home addresses, and bank account numbers. They didn't have any security or access passwords, either. The breach did not affect consumers outside of the United States. Cash app's next step There is still a lot we don't know about the situation. It took four months for Block to discover the Cash App data breach. The Inc. hasn't finished its investigation into the matter, but it doesn't expect it to have an impact on its operations or financial results. Also the shares of Block (NASDAQ: SQ) fell 3.6% in the early session to $129.86. In its filing, Block shared the following statement: “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 the information of its customers,” What do you think about this news?
