exploiting-insecure-data-storage-in-mobile
Identifies and exploits insecure local data storage vulnerabilities in Android and iOS mobile applications including unencrypted databases, world-readable files, insecure SharedPreferences, plaintext credential storage, and improper keychain/keystore usage. Use when performing mobile penetration testing focused on OWASP M9 (Insecure Data Storage) or assessing compliance with MASVS-STORAGE requirements. Activates for requests involving mobile data storage security, local storage exploitation, SharedPreferences analysis, or mobile data leakage assessment.

# Exploiting Insecure Data Storage in Mobile
## When to Use
Use this skill when:
- Assessing whether mobile applications store sensitive data securely on the device filesystem
- Testing for credential leakage through SharedPreferences, SQLite databases, or plists
- Evaluating keychain/keystore implementation for proper access control attributes
- Performing data-at-rest security assessment during mobile penetration tests
**Do not use** this skill on production user devices without authorization -- data extraction techniques require physical access or root/jailbreak privileges.
## Prerequisites
- Rooted Android device or emulator with ADB access
