๐ŸŒŸ , 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

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
