Default key derivation uses single MD5 iteration, making encrypted data easily brutable

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.

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

Dynamically creates script elements, potentially loading external malicious code.

Injects and executes scripts in web pages programmatically.

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

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

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

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

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

CSRF token leakage via cross-site requests

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

Decodes base64 data, commonly used to hide malicious payloads.

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.

Uses XMLHttpRequest to make network calls.

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

Line exceeds 5000 characters (entropy: 5.638263078473739)

SSRF via crafted redirect

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.

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

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.

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

String with entropy 6 bits — may be encoded/encrypted data
