Extension Auditor - Security & Privacy Analyzer

Don't sacrifice privacy for convenience.

๐ŸŒŸ After watching MegaLag's Video about the PayPal Honey browser extension, I had a wake-up call. And as it turns out, this is exactly the motivation I needed to create something that solves this and empowers everyday users to take back control of their data privacy. ๐Ÿ’ก It was eye-openingโ€”and infuriating. As someone who cares about ๐Ÿ›ก๏ธ user privacy and security, I couldnโ€™t ignore the risks that browser extensions like Honey can pose. ๐Ÿš€ So, I built... Introducing: Extension Auditor ๐Ÿ› ๏ธ Extension Auditor is a browser extension that helps users understand and evaluate the security implications of their installed browser extensions. It provides real-time security analysis and risk assessment of extensions based on their permissions, capabilities, and potential security impacts. ๐Ÿ”‘ Features ๐Ÿ” Real-time Security Analysis: Instantly analyzes installed extensions for security considerations. โš ๏ธ Risk Classification: Categorizes findings into Critical, High, Medium, and Low severity levels. ๐Ÿ›ก๏ธ Permission Analysis: Detailed explanation of each extensionโ€™s permissions and their security implications. ๐ŸŒ Host Access Analysis: Identifies extensions with broad host permissions or access to sensitive domains. ๐Ÿ“Š Comprehensive Report: Generates detailed security reports with specific findings and potential risks. ๐Ÿ•ต๏ธ Privacy Focus: Runs locally in your browser with minimal required permissions. ๐Ÿ‘ฅ Who can benefit ๐ŸŒ Everyday Internet Users: Stay informed and secure. ๐ŸŽฅ Content Creators: Vet extensions before promoting them to your audience. ๐Ÿ”’ Cybersecurity Professionals: A great starting point for pentesting browser extensions to guide deeper dynamic and runtime analysis. ๐Ÿ” Privacy Professionals: Discern privacy concerns of using an extension and compare advertised privacy practices vs. actual use. ๐Ÿ› ๏ธ How it works Extension Auditor analyzes extensions based on several factors: ๐Ÿ”‘ Permission Analysis: Evaluates the permissions requested by extensions and their potential security implications. ๐ŸŒ Host Access: Identifies broad host permissions that could pose privacy risks. ๐Ÿ’ป Content Script Analysis: Examines how extensions interact with web pages. ๐Ÿ“œ Manifest Analysis: Reviews extension manifest settings for security best practices. ๐Ÿ“ˆ Combined Risk Assessment: Calculates overall risk based on multiple security factors. ๐Ÿ”’ Risk Rating Methodology ๐Ÿšจ Critical: Highly sensitive permissions or combinations that could be dangerous if misused. โš ๏ธ High: Permissions that could potentially be used maliciously. โšก Medium: Permissions that require caution as they provide significant capabilities. โœ… Low: Permissions with limited potential for misuse. ๐Ÿ›ก๏ธ Privacy Extension Auditor requires only two permissions: management: To access information about installed extensions. tabs: To display the analysis interface. ๐Ÿ’ก The extension runs entirely in your browser and: โŒ Does not collect any personal data. โŒ Does not send data to external servers. โŒ Does not modify any other extensions. โŒ Does not modify webpage content. ๐Ÿ”‘ Permissions Explained A permission is either one of a list of known strings, such as activeTab, or a match pattern giving access to one or more hosts. Remove any permission that is not needed to fulfill the single purpose of your extension. โš™๏ธ The management permission is essential for this extension because it allows us to: ๐Ÿ“‹ List and access information about installed extensions using chrome.management.getAll(). ๐Ÿ“– Get detailed extension information using chrome.management.get(extensionId). ๐Ÿ”„ Monitor extension lifecycle events through listeners. We use this permission to: ๐Ÿ“œ Get manifest details. ๐Ÿ”‘ Check permissions. ๐Ÿ“‚ Monitor content scripts. ๐Ÿ›ก๏ธ Analyze security settings. ๐Ÿ”„ Track extension states (enabled/disabled). ๐ŸŒ Get host permissions. โš™๏ธ Access CSP (Content Security Policy) settings. Without the management permission, it would be impossible to perform security analysisโ€”making this the core permission that enables the extensionโ€™s main functionality. ๐ŸŒ Letโ€™s make browsing saferโ€”for all of us. ๐ŸŒŸ
