Mobile Interceptor (PT)

Mobile Interceptor (PT) is a mobile-first HTTP traffic interceptor designed for authorized penetration testing on Firefox Android.

Features:

• INTERCEPT mode — Block HTTP requests, inspect and edit them (method, URL, headers, body), then forward or drop
• OBSERVE mode — Passively capture traffic without blocking (read-only)
• Repeater — Save and replay requests with modifications for manual testing
• Notes — Save request/response pairs for later analysis
• Scope control — Allowlist-based domain filtering (default-deny: nothing is intercepted until you configure targets)
• Audit log — Track all actions (forward, drop, mode changes, policy changes)

Security & Privacy:

• All data stored locally only (browser.storage.local) — no remote servers, no telemetry
• Sensitive headers (Authorization, Cookie, etc.) are automatically redacted in display and export
• Rate limiting on request replay
• Retention limits on all stored data (notes, repeater, audit log)
• OFF by default — no interception until explicitly enabled by the user

Important: This tool is intended exclusively for authorized security testing. Only use it on systems you have explicit permission to test.
