Insufficient Binary Protections
Mobile app lacks code obfuscation, anti-tampering, or anti-debugging protections — making it easy to reverse engineer, modify, and redistribute.
How It Works
Without binary protections, attackers can easily reverse engineer your mobile app. They can decompile the code to find hardcoded secrets, understand business logic, find vulnerabilities, bypass license checks, or create modified versions. While obfuscation doesn't prevent determined attackers, it significantly raises the bar. React Native apps are especially vulnerable since JavaScript bundles are readable text by default.
// React Native — no obfuscation configured
// metro.config.js
module.exports = {
transformer: {
// Default config, JS bundle is readable
}
};// metro.config.js with obfuscation
module.exports = {
transformer: {
minifierConfig: {
mangle: true,
compress: { drop_console: true }
}
}
};

In 2015, attackers reverse-engineered the Starbucks mobile app, finding that it stored usernames and passwords in cleartext. This led to account hijacking and unauthorized gift card purchases worth millions of dollars.
How to Prevent It
- Enable code obfuscation (ProGuard for Android, Bitcode for iOS)
- Use anti-tampering detection to catch modified binaries
- Strip debug symbols from release builds
- Consider solutions like DexGuard or iXGuard for sensitive apps

Improper Credential Usage
criticalHardcoded API keys, passwords, or tokens directly in mobile app source code — easily extracted by decompiling the app bundle.
Mobile Supply Chain Security
mediumVulnerable SDKs, outdated native libraries, or compromised third-party modules in your mobile app introduce security risks from your dependencies.
Insecure Authentication/Authorization
highMobile apps with weak authentication — storing sessions insecurely, missing token refresh, or authorization checks only on the client side.
Insufficient Input/Output Validation
mediumMobile apps that don't validate user input or sanitize output are vulnerable to injection attacks, data corruption, and unexpected behavior.
