Windscribe - Free Proxy and Ad BlockerSecurity Analysis

Extension intercepts network traffic and sends data externally — potential man-in-the-middle behavior.

Extension manages other extensions and executes dynamic code — behavior consistent with malware dropper.

Extension has access to all sites and captures keyboard input — behavior consistent with a keylogger.

Creates functions from strings, similar to eval(), often used to hide malicious code.

Listens for keyboard events, a common technique used by keyloggers.

Dynamically creates script elements, potentially loading external malicious code.

Manages other extensions, could disable security tools or install malware.

Dynamically sets a script's src attribute to load external code at runtime.

Object.defineProperty() called on window — can intercept and override built-in browser APIs.

Creates a function from a string (new Function()), similar to eval().

JavaScript files are accessible to ALL websites. Any page can load and interact with these scripts, enabling web→extension attacks.

Extension tracks open tabs and communicates with external servers — potential browsing surveillance.

Dynamically creates iframe elements, which can be used to load external content or hide malicious UI.

Sends messages via Chrome runtime, could communicate with external services.

Modifies window.location to redirect the user, potentially to phishing or malicious pages.

Decodes base64 data, commonly used to hide malicious payloads.

Uses XMLHttpRequest to make network calls.

Uses document.write() which can inject arbitrary HTML/scripts into pages.

Makes HTTP requests to external servers, may be used for data exfiltration.

Fetches external URL: https://nosslscribe.com

JavaScript file could not be parsed. May contain obfuscated or minified code.

Line exceeds 5000 characters (entropy: 5.581395636495819)

This extension does not define a Content Security Policy. A CSP helps prevent XSS and code injection attacks.

Web-accessible resources use <all_urls> or wildcard patterns, exposing resources to every website.

Reads or writes to localStorage, which may contain sensitive site data.

Creates a Web Worker, which runs code in a separate thread — can be used for background computation or crypto mining.

Sets innerHTML directly, which can lead to XSS if used with untrusted data.

Encodes data to base64, may be used for data exfiltration.
