Personal data breaches happen in many different ways. In some cases, it may be that a company’s data was hacked and personal information like credit card numbers or social security numbers were compromised. These types of situations can happen often to large retailers like Target, Walmart, and others. Personal data breaches may also be more limited. An employee's briefcase may be lost or stolen and contain sensitive documents that include personal customer information. Other examples may be an employee who clicked on a harmful email that installed malware on company devices that infiltrated a database and could have accessed sensitive data.
