Your Data

The Detailed Seo Extension accesses data on your device, including the current webpage's content and metadata. It sends this data to various domains for analysis, including www.w3.org, www.facebook.com, and ahrefs.com.

Technical Details

The extension makes XHR requests to multiple domains, including www.w3.org, www.facebook.com, and ahrefs.com. It also uses the Fetch API and sets up event listeners. The content script injection is none.

Code Findings

Dynamic JS ImportMedium

The extension dynamically imports JavaScript files, which can be used for legitimate purposes like SEO analysis but also poses a risk if exploited.

Technical: The extension uses the import() function to load JavaScript files dynamically. This can be used to inject malicious code or exploit vulnerabilities in the browser.

💡 Legitimate extensions use dynamic imports to load scripts based on user preferences or page content.

innerHTML AssignmentMedium

The extension assigns innerHTML values, which can be used for legitimate purposes like SEO analysis but also poses a risk if exploited.

Technical: The extension uses the innerHTML property to assign values to HTML elements. This can be used to inject malicious code or exploit vulnerabilities in the browser.

💡 Legitimate extensions use innerHTML assignments to update page content based on user interactions.

String.fromCharCode ObfuscationMedium

The extension uses String.fromCharCode for obfuscation, which can be used for legitimate purposes like SEO analysis but also poses a risk if exploited.

Technical: The extension uses the String.fromCharCode function to encode strings. This can be used to hide malicious code or exploit vulnerabilities in the browser.

💡 Legitimate extensions use obfuscation techniques to protect intellectual property or prevent reverse engineering.

Makes XHR RequestsInfo

The extension makes XHR requests to multiple domains for analysis.

Technical: The extension uses the XMLHttpRequest object to make HTTP requests to various domains. This is a common practice for legitimate extensions that need to fetch data from external sources.

💡 Legitimate extensions use XHR requests to fetch data from external APIs or services.

Runs on ALL WebsitesHigh

The extension runs on all websites, which can pose a significant risk if exploited.

Technical: The extension uses the declarativeNetRequestWithHostAccess permission to run on all websites. This poses a significant risk if exploited, as it allows the extension to inject malicious code or exploit vulnerabilities in any website.

💡 Legitimate extensions use this permission to provide universal functionality across multiple websites.

Broad Host PermissionsHigh

The extension has broad host permissions, which can pose a significant risk if exploited.

Technical: The extension uses the declarativeNetRequestWithHostAccess permission to access multiple domains. This poses a significant risk if exploited, as it allows the extension to inject malicious code or exploit vulnerabilities in any website.

💡 Legitimate extensions use this permission to provide universal functionality across multiple websites.

Can Block/Modify Network RequestsHigh

The extension can block or modify network requests, which poses a significant risk if exploited.

Technical: The extension uses the declarativeNetRequestWithHostAccess permission to block or modify network requests. This poses a significant risk if exploited, as it allows the extension to inject malicious code or exploit vulnerabilities in any website.

💡 Legitimate extensions use this permission to provide universal functionality across multiple websites.

Uses postMessage for Cross-Origin CommsInfo

The extension uses the postMessage API for cross-origin communication, which is a common practice for legitimate extensions.

Technical: The extension uses the postMessage function to communicate with other scripts across different domains. This is a common practice for legitimate extensions that need to interact with external services or APIs.

💡 Legitimate extensions use this API to communicate with external services or APIs.

Sets up Event ListenersInfo

The extension sets up event listeners, which is a common practice for legitimate extensions.

Technical: The extension uses the addEventListener function to set up event listeners. This is a common practice for legitimate extensions that need to respond to user interactions or page events.

💡 Legitimate extensions use this API to respond to user interactions or page events.

Bottom Line

The Detailed Seo Extension has some concerning findings, including broad host permissions and the ability to block/modify network requests. While it provides legitimate functionality for SEO analysis, these risks should be carefully evaluated by users before installing or using the extension.
