Context-Aware Verdict
This section provides a Claude-based AI analysis that applies additional context to the risk. Results are not guaranteed to be accurate.
HIGH
Risk Level
Trust Factors:
The extension appears to be developed by or for Expedia Group, given its focus on travel-related domains (Expedia, Hotels.com, VRBO, etc.). However, several concerning factors undermine trust: extremely low user adoption (332 users), minimal rating data (only 2 reviews), missing developer information, and no clear description of functionality. The version number (0.0.58) suggests this may be in early development or testing phases.
Concerns:
The extension requests powerful permissions that create significant privacy and security risks. The cookies permission allows access to sensitive authentication data across all specified domains. The tabs permission enables monitoring and manipulation of browsing activity. The storage permission, while less critical, allows persistent data collection. Most concerning is the extensive list of host permissions covering dozens of travel-related domains plus internal testing environments, creating a broad attack surface. The lack of transparency about the extension's actual purpose makes it impossible to verify if these permissions are necessary.
Recommendations:
Given the high risk level, avoid installing this extension unless you have a specific business need and can verify its legitimacy through official Expedia channels. If installation is necessary, use a separate Chrome profile to isolate potential risks. Monitor your accounts on affected domains for unusual activity. Consider that this may be an internal tool not intended for public distribution, which would explain the limited user base and missing documentation.
