Did You Know?

• Data Breach in Healthcare Organizations: Data breaches in healthcare organizations like Kaiser Permanente are becoming increasingly common. These incidents expose sensitive personal and health information of patients, which can have serious consequences, including identity theft and insurance fraud. Healthcare organizations are a prime target for cybercriminals because of the value of the data they hold.

• Third-Party Vendors and Tracking Codes: Third-party vendors are companies that provide services to websites and apps, such as analytics, advertising, and functionality enhancements. In this case, Kaiser Permanente used third-party vendors that received personal information through tracking codes. These codes can be embedded in websites and apps to collect data about user interactions. If not properly managed, they can lead to data leaks and breaches.

• IP Addresses: An IP address is a unique numerical label assigned to each device participating in a computer network. In the context of the Kaiser Permanente data breach, IP addresses of current and former patients were exposed. An IP address can be used to identify the geographical location of a user, which can potentially be used for malicious purposes, such as stalking or targeted advertising.
