Ghostery Tracker & Ad Blocker - Privacy AdBlockSecurity Analysis

Extension has cookie access and sends data to external servers — potential session token theft.

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

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

Injects and executes scripts in web pages programmatically.

Accesses browser cookies programmatically, could be used to steal session tokens.

Uses eval() to execute dynamic code, a common technique for obfuscation and code injection.

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

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

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

Uses data URIs to execute code, bypassing content security policies.

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

Uses eval() to execute dynamic code — a common vector for code injection.

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.

Decodes base64 data, commonly used to hide malicious payloads.

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

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

Uses XMLHttpRequest to make network calls.

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

Intercepts form submissions, could capture login credentials.

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

Line exceeds 5000 characters (entropy: 4.192420149852696)

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.

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

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

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

String with entropy 5.95 bits — may be encoded/encrypted data

object-src is not set to 'none'. Plugins like Flash can be embedded, which may allow code execution.
