Decloak Session Capture door Stephen Gray

Decloak is an automated web security scanner. Paste any URL and get a free, instant report in about 15 seconds - no login required - covering HTTP/TLS posture, JavaScript vulnerabilities, third-party scripts and tag managers, and more.

Decloak's paid Enterprise tier goes further: an AI agent crawls your whole site, investigates what it finds, and produces audit-ready reports for teams tracking SOC2 or ISO 27001 compliance.

This extension is a companion for the Enterprise tier's authenticated scans - it does nothing on its own and requires a Decloak account already open to a "New scan" dialog.

Enterprise's authenticated scan mode crawls your site as a logged-in user, which means it needs your session. For most sites that's easy to script. For sites using passkeys or WebAuthn (Hanko, Face ID/Touch ID sign-in, security keys), there's no credential to script — the only way in is a session that already exists in your browser. This extension captures that session so Decloak can use it.

How it works

1. Start a new Enterprise scan in your Decloak dashboard, choose "Authenticate as a logged-in user," and click "Get a capture code."
2. Open the site you want scanned in a tab, log in normally, then click this extension's icon.
3. Click "Capture session for Decloak" — it asks for permission on just that tab's site, nothing else.
4. Paste the capture code from the dashboard and click "Send to Decloak."

What it captures

Cookies, localStorage, and sessionStorage for the one site you're currently on. Nothing else — no browsing history, no other tabs, no data from sites you haven't explicitly clicked "capture" on.

What it doesn't do

• No install-time permissions. It asks for site access only when you click, only for that site.
• No account or API key lives in the extension. The one-time capture code from your Decloak dashboard is the only credential involved, and it expires in 15 minutes whether you use it or not.
• Nothing is stored by the extension itself. Closing the popup clears the capture. There's no storage permission in the manifest because there's nothing to persist.
• The capture is single-use. Once Decloak's scan consumes it, the code is dead.

Why this needs the cookies permission

The entire purpose of this extension is capturing a session for your own authenticated security scan, scoped to the one site you click on. There's no other way to read cookies for a site from an extension. We don't request broad host permissions at install time - you grant access per-site, per-use, from the popup.
