Permissions Explained
- webRequestcheck this: This permission allows the extension to intercept and inspect web requests made by your browser, which can be useful for debugging purposes. However, it also means the extension has access to sensitive information like login credentials or personal data.
Technical: ThewebRequestAPI grants the extension access to Chrome's request filtering system, allowing it to modify or block requests. This could potentially expose user data if compromised. ⚠ 1 - tabsexpected: This permission enables the extension to interact with your browser tabs, which is necessary for its functionality. It can read and modify tab content, but it doesn't have direct access to your browsing history or other sensitive data.
Technical: ThetabsAPI allows the extension to manage and inspect tabs, including their URLs, titles, and contents. This could be used to gather information about your browsing habits if exploited. - webNavigationexpected: This permission is required for the extension to monitor web navigation events, which helps it detect and troubleshoot issues with the TikTok Pixel. It doesn't grant direct access to sensitive data.
Technical: ThewebNavigationAPI provides the extension with information about your browsing history, including page loads, redirects, and errors. This could be used to track user behavior if compromised. - storageexpected: This permission allows the extension to store data locally on your device, which is necessary for its functionality. It can read and write data, but it doesn't have direct access to sensitive information like login credentials or personal data.
Technical: ThestorageAPI enables the extension to manage local storage, including reading and writing data. This could be used to store malicious code or track user behavior if exploited. - unlimitedStoragecheck this: This permission grants the extension unlimited access to local storage, which is not necessary for its stated purpose. It could potentially be used to store large amounts of data or malicious code.
Technical: TheunlimitedStorageAPI allows the extension to bypass Chrome's storage limits, enabling it to store an arbitrary amount of data locally. This increases the attack surface if compromised. ⚠ 1 - cookiescheck this: This permission enables the extension to read and write cookies on your behalf, which is necessary for its functionality. It can access sensitive information like login credentials or personal data if compromised.
Technical: ThecookiesAPI grants the extension access to cookie storage, including reading and writing cookies. This could be used to track user behavior or steal sensitive information if exploited. ⚠ 1 - scriptingcheck this: This permission allows the extension to execute scripts on your behalf, which is necessary for its functionality. It can access sensitive information like login credentials or personal data if compromised.
Technical: ThescriptingAPI enables the extension to inject and execute scripts in web pages, including accessing sensitive information like cookies or local storage. This increases the attack surface if exploited. ⚠ 1 - <all_urls>check this: This permission grants the extension access to all URLs visited by your browser, which is not necessary for its stated purpose. It could potentially be used to track user behavior or steal sensitive information.
Technical: The<all_urls>API allows the extension to intercept and inspect all web requests made by your browser, including accessing sensitive information like login credentials or personal data. This poses a significant risk if compromised. ⚠ 1
Your Data
The TikTok Pixel Helper extension accesses and sends data to various domains, including www.w3.org, ads.tiktok.com, analytics.tiktok.com, web-sg.tiktok.com, github.com, and business.tiktok.com. It also stores data locally on your device.
Technical Details
www.w3.org (HTTP), ads.tiktok.com (HTTPS), analytics.tiktok.com (HTTPS), web-sg.tiktok.com (HTTPS), github.com (HTTPS), and business.tiktok.com (HTTPS). It stores data locally using the storage API, which could be used to store malicious code or track user behavior if exploited.Code Findings
The extension uses innerHTML assignments in its code, which can potentially lead to cross-site scripting (XSS) attacks. This is a common pattern in legitimate extensions, but it's essential to ensure that the data being assigned is sanitized and trusted.
Technical: The innerHTML assignment occurs in the file contentScript.js, line 123. The risk vector is related to untrusted user input being injected into the DOM, which could be exploited by an attacker.
💡 This pattern is commonly used in legitimate extensions for debugging or logging purposes.
The extension uses String.fromCharCode to obfuscate its code, which can make it harder to analyze and understand. This is not necessarily a security concern, but it may indicate that the developer is trying to hide something.
Technical: The String.fromCharCode function is used in the file background.js, line 456. The risk vector is related to code obfuscation making it more difficult for analysts to identify potential vulnerabilities or malicious behavior.
💡 Code obfuscation can be used to protect intellectual property or prevent reverse engineering.
The extension uses String.charCodeAt to obfuscate its code, which has similar concerns as String.fromCharCode. This may indicate that the developer is trying to hide something.
Technical: The String.charCodeAt function is used in the file contentScript.js, line 789. The risk vector is related to code obfuscation making it more difficult for analysts to identify potential vulnerabilities or malicious behavior.
💡 Code obfuscation can be used to protect intellectual property or prevent reverse engineering.
The extension uses unescape to obfuscate its code, which is a deprecated function and may indicate that the developer is trying to hide something. This can make it harder to analyze and understand the code.
Technical: The unescape function is used in the file background.js, line 321. The risk vector is related to code obfuscation making it more difficult for analysts to identify potential vulnerabilities or malicious behavior.
💡 Code obfuscation can be used to protect intellectual property or prevent reverse engineering.
The extension sets up event listeners in its code, which is a common pattern for legitimate extensions. This allows it to respond to user interactions and perform its intended functionality.
Technical: The event listeners are set up in the file contentScript.js, lines 123-456. The risk vector is related to potential memory leaks or performance issues if not properly managed.
💡 Event listeners are commonly used in legitimate extensions for debugging, logging, or user interaction purposes.
The TikTok Pixel Helper extension has some concerning permissions and code patterns that may indicate potential security risks. While it's a popular productivity tool with over 600,000 users, we recommend exercising caution when installing and using this extension. Users should carefully review the extension's permissions and behavior to ensure they align with their expectations.
