These are the top security risks facing mobile applications today. Use this guide to strengthen your app security posture and protect users from real-world attacks.

1. 🔓 Improper Credential Usage

Description: Storing hardcoded credentials, API keys, or passwords insecurely.

Never hardcode secrets. Use secure device storage.

Use Android Keystore / iOS Keychain
Remove secrets from app binaries
Rotate credentials frequently

Reference: OWASP M1

2. 🗂 Insecure Data Storage

Description: Storing sensitive data (PII, tokens, passwords) unencrypted or in shared storage.

Assume the device is compromised. Encrypt everything.

Encrypt data at rest
Use platform-secure APIs
Don’t store sensitive data unless necessary

Reference: OWASP M2

3. 🔌 Insecure Communication

Description: Lack of encryption or weak SSL/TLS implementations expose data in transit.

Use TLS 1.2+ and enforce certificate pinning.

Use HTTPS everywhere
Avoid custom SSL handling
Use secure network libraries

Reference: OWASP M3

4. 👨‍💻 Insecure Authentication & Authorization

Description: Weak auth mechanisms allow impersonation or unauthorized access.

Protect sessions. Avoid device ID-based authentication.

Use OAuth 2.0 / OpenID Connect
Use secure token storage
Enforce session expiration

Reference: OWASP M4

5. 🧑‍🏫 Insufficient Input Validation

Description: Improper input validation can cause crashes, bypasses, or injections.

Validate inputs on both client and server side.

Use length, type, and format checks
Block dangerous characters
Sanitize inputs used in logic or output

Reference: OWASP M5

6. ⚙️ Inadequate Supply Chain Security

Description: Using untrusted or unverified SDKs, plugins, and dependencies.

Third-party code is your code. Trust but verify.

Vet third-party SDKs
Scan dependencies for known vulnerabilities
