Scans Android APKs for Firebase security misconfigurations including open databases, storage buckets, authentication issues, and exposed cloud functions. Use when analyzing APK files for Firebase vulnerabilities, performing mobile app security audits, or testing Firebase endpoint security. For authorized security research only.

Enumerating Cloud Functions and testing for unauthenticated access
Mobile app security assessments involving Firebase backends
Authorized penetration testing of Firebase-backed applications
When NOT to Use
Scanning apps you do not have explicit authorization to test
Testing production Firebase projects without written permission
When you only need to extract Firebase config without testing (use manual grep/strings instead)
For non-Android targets (iOS, web apps) - this skill is APK-specific
When the target app does not use Firebase
Rationalizations to Reject
When auditing, reject these common rationalizations that lead to missed or downplayed findings:
"The database is read-only so it's fine" - Data exposure is still a critical finding; PII, API keys, and business data may be leaked
"It's just anonymous auth, not real accounts" - Anonymous tokens bypass auth != null rules and can access "authenticated-only" resources
"The API key is public anyway" - A public API key does not justify open database rules or disabled auth restrictions
"There's no sensitive data in there" - You cannot know what data will be stored in the future; insecure rules are vulnerabilities regardless of current content
"It's an internal app" - APKs can be extracted from any device; "internal" apps are not protected from reverse engineering
"We'll fix it before launch" - Document the finding; pre-launch vulnerabilities frequently ship to production
