File Notification Systems in Windows, Linux, and Android Leak Sensitive User Activity

Researchers have demonstrated that file-change notification systems in Windows, Linux, and Android operating systems can leak sensitive user activity information. The vulnerability in these file notification systems allows for the exposure of keystroke timing data, browsing activity, and WhatsApp media events. The research shows that these built-in operating system features, designed to monitor file system changes, can be exploited to track user behavior across multiple platforms including Windows, Linux, Android, and macOS as indicated in the tags.
