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.

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

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

Dynamically creates script elements, potentially loading external malicious code.

Injects and executes scripts in web pages programmatically.

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

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

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

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

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.

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.

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

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

Decodes base64 data, commonly used to hide malicious payloads.

Uses XMLHttpRequest to make network calls.

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

Line exceeds 5000 characters (entropy: 5.440135481531251)

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

Content script matches <all_urls>, executing on every website the user visits.

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

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

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.

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.

Extension accepts messages from 3 external pattern(s). Verify these are trusted origins.
