Mobile Security (Advanced)

Custom URL schemes without host verification let malicious apps intercept your app's deep links and steal OAuth tokens or sensitive parameters.

Sensitive data copied to the clipboard (passwords, tokens, card numbers) persists there indefinitely and can be read by any app.

Banking and payment screens without screenshot protection allow sensitive data to be captured by malware or appear in Android's recent apps screen.

Without certificate pinning, attackers on the same network can intercept your app's HTTPS traffic with a rogue certificate authority.

Running a financial or health app on a rooted or jailbroken device means all security controls can be bypassed by the device owner.

Biometric authentication that only runs client-side can be bypassed by patching the app binary — the server must validate the session independently.
