AdGuard AdBlockerSecurity Analysis

Contains cryptocurrency mining code indicators.

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.

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

Passes a string to setTimeout(), which is evaluated like eval() — a code injection vector.

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

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

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

Dynamically creates script elements, potentially loading external malicious code.

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

setTimeout() called with a string argument — equivalent to eval() and executes the string as code.

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

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

Decodes base64 data, commonly used to hide malicious payloads.

Uses XMLHttpRequest to make network calls.

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.

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

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

Line exceeds 5000 characters (entropy: 5.453808767339071)

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 5.52 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 registers a DevTools panel page. DevTools extensions have access to inspected page network traffic and DOM.
