name	exploiting-insecure-data-storage-in-mobile
description	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.

Exploiting Insecure Data Storage In Mobile

Overview

Cybersecurity skill for exploiting insecure data storage in mobile. Follows industry best practices and security standards.

When to Use

Trigger phrases:

• "exploiting insecure data storage in mobile"
• "Assessing whether mobile applications store sensitive data securely on the devic"
• "Testing for credential leakage through SharedPreferences, SQLite databases, or p"
• "Evaluating keychain/keystore implementation for proper access control attributes"

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.

When NOT to Use

• When you lack proper authorization for testing
• For production systems without change management
• When the task requires legal or compliance expertise beyond technical scope

Prerequisites

• Rooted Android device or emulator with ADB access
• Jailbroken iOS device with SSH access or Objection-patched IPA
• ADB (Android Debug Bridge) for Android filesystem access
• SQLite3 CLI for database inspection
• Frida/Objection for runtime data extraction
• Target application installed and exercised (logged in, data cached)

Legal Notice: This skill is for authorized security testing and educational purposes only. Unauthorized use against systems you do not own or have written permission to test is illegal and may violate computer fraud laws.

Workflow

# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": ,
}

 () -> :
     {k: re.findall(v, text)  k, v  IOC_PATTERNS.items()}
