Jetpack Compose doesn't automatically secure Android apps. Three critical vulnerabilities are explained: Task Hijacking (StrandHogg) exploits taskAffinity to hijack app task stacks, preventable by setting launchMode to singleTask. Tapjacking uses transparent overlays to intercept touches, mitigated by setting filterTouchesWhenObscured on views. Intent Injection through deep links can execute unauthorized actions, requiring strict input validation. Additional protections include FLAG_SECURE for preventing screenshots of sensitive screens, custom modifiers for tapjacking protection, and secure WebView configuration. A comprehensive security checklist covers manifest configuration, UI interaction safety, and data handling best practices.
