Context-Aware Verdict

HIGH

Risk Level

Trust Factors:

- The extension has a relatively high number of users (10,000) and a good rating (4.8/5), which suggests some level of trust from the user community.

- The developer is a registered company (Supademo, Inc.), which adds some credibility.

Concerns:

- The extension requests several high-risk permissions, including tabs, webNavigation, and broad host/content script permissions, which could potentially be abused for malicious purposes like tracking browsing activity, compromising security, or stealing sensitive data.

- The broad permissions seem unnecessary for an extension that claims to provide "AI interactive demos," raising questions about the extension's true purpose.

Recommendations:

- Exercise caution when installing this extension, as the requested permissions are excessive for its stated functionality.

- Consider running the extension in a separate browser profile or a sandboxed environment to isolate it from your main browsing activity.

- Closely monitor the extension's behavior and network activity for any suspicious activities.

- Regularly review the extension's permissions and revoke any unnecessary ones.

- If possible, seek alternative extensions with similar functionality but fewer permissions or from more reputable developers.
