cloudflare-turnstile-reversed

A sourced teardown of how Cloudflare Turnstile fingerprints and scores browsers, plus a live capture tool. Every claim is cited or tagged [observed] / (inferred) — no filler, no memory guesses.

Need it solved, not studied? Peak solves Cloudflare Turnstile and the 5s challenge via API — pay per success, from $1/1K, free key, no card. (reCAPTCHA coming soon.)

Docs

• docs/fingerprinting/ — the deep layer: 8 per-field teardowns (behavioral, automation-tells, canvas, WebGL, audio, device-coherence, TLS/HTTP2, IP/scoring/PoW), each cited and tagged confirmed/observed/inferred. Start at its index.
• docs/03-fingerprinting.md — the one-page fingerprinting overview (surface map; the docs/fingerprinting/ set goes deeper per field).
• docs/04-loader-internals.md — concrete code from the real bundle: the [native code] hook-detection function, the isTrusted interaction gate, stack/timing telemetry, the endpoint builder.
• docs/01-challenge-flow.md — the live request flow (loader → versioned bundle → challenge-platform), captured.
• docs/02-widget-params.md — the widget parameters the bundle reads (sitekey, cData, action, chlPageData).

Tool

tools/capture.py — pull the sitekey / cData / action off a page; --solve returns a token.

python tools/capture.py https://example.com/
PEAK_API_KEY=pk_your_key python tools/capture.py https://example.com/ --solve

Scope

Is: a sourced map of the fingerprinting surface (which signals, collected where) and capture tooling. Isn’t: a byte-level deobfuscation of the versioned bundle, the challenge-platform payload schema, or token construction — and not a token-forgery method, since tokens are single-use and validated server-side via siteverify.
