Data Leak Inspector

Find sensitive data. Fix risky permissions.

Data Leak Inspector is a CLI tool that helps you identify potentially exposed files in your storage systems — starting with Google Drive.

Instead of scanning file contents, DLI analyzes metadata and permissions to quickly highlight files that may be publicly accessible or shared.

🚀 Features

• 🔍 Metadata-based scanning (no file content access)
• ☁️ Google Drive integration
• 📂 Scans all files (including nested ones)
• 🔐 Exposure detection based on permissions
  • Public (anyone with link)
  • Shared (users, groups, domain)
  • Private
• 💬 Human-readable explanations
• 📊 Clean CLI output with summaries
• ⚡ Progress bar during scanning

🧠 How It Works

DLI does not read file contents.

Instead, it analyzes:

• File permissions (Google Drive API)
• Sharing settings
• Basic metadata (name, type, timestamps)

This allows:

✔ Faster scans
✔ Lower permissions required
✔ Easier approval for Google APIs
✔ Better privacy guarantees

📸 Example Output

Scanning 12/120: payroll.xlsx ████████████ 100%

SCAN RESULTS (BASIC)

[PUBLIC ] payroll_2024.xlsx
          → anyone with link (reader)

[SHARED ] team_notes.docx
          → shared with 3 user(s)

[PRIVATE] personal.txt
          → only accessible by owner

Summary:
  Total files: 120
  Public: 5
  Shared: 18
  Private: 97
