Tamper detection refers to the process of detecting any unauthorized modifications or tampering attempts made to the code or data of a mobile application. The purpose of tamper detection is to prevent users from using a mobile app that has been tampered with. Without it, the security and privacy of app users can be compromised, leading to data breaches, theft of sensitive information, or even malicious attacks.
Anti-tampering is used interchangeably with tamper detection.
Performing unauthorized modifications on mobile apps can be done through various methods. Here are some common ways attackers can modify mobile apps:
By exploiting these vulnerabilities, attackers can perform unauthorized modifications on mobile apps, compromising the security and privacy of the app's users.
Detecting unauthorized modifications or tampering attempts on a mobile app involves using various techniques to monitor the integrity of the app and its environment. Common anti-tampering techniques that can be used in mobile apps include:
By using one or more of these techniques, mobile app developers can implement tamper detection for mobile apps to protect against unauthorized modifications, data breaches, and other security threats. No single technique can provide complete protection against all types of app tampering attempts. Therefore a combination of techniques is usually needed for effective tamper detection.
Tamper detection should be part of a Mobile RASP (Runtime Application Self-Protection) solution.
