Kaiser Permanente: Data breach may impact 13.4 million patients

Kaiser Permanente disclosed that certain online trackers previously installed on its websites and mobile applications may have transmitted personal information for about 13.4 million current and former members to third-party vendors including Google, Microsoft Bing, and X. The leaked data reportedly included IP addresses, names, indicators that a user was signed in, website and app navigation behavior, and health-related search terms; it did not include passwords, SSNs, or financial data. The trackers were removed after an internal review, no misuse is currently known, and affected individuals will be notified.
