StylusSecurity Analysis

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.

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

Dynamically creates script elements, potentially loading external malicious code.

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

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.

Injects and executes scripts in web pages programmatically.

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

Content script runs at document_start in ALL frames on ALL URLs. This gives the extension deep access to every page load, including iframes.

Uses XMLHttpRequest to make network calls.

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

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

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

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

Fetches external URL: https://api.dropboxapi.com/2/auth/token/revoke

Line exceeds 5000 characters (entropy: 5.318585234016491)

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.

Extension uses tab tracking APIs (onUpdated/query) and communicates with external servers — potential browsing surveillance.

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

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