Context-Aware Verdict

HIGH

Risk Level

Trust Factors:

- The extension has a relatively high number of users (100,000), which could indicate some level of trust.

- However, the lack of developer information and a low rating (3.7/5) raise concerns about the trustworthiness of the extension.

Concerns:

- The extension requests several high-risk permissions, including downloads, webRequest, and webNavigation, which could potentially be used maliciously to compromise security or privacy.

- The broad host permissions (*://*/*.m3u8) allow the extension to access many websites, increasing the risk of data theft or tracking browsing activity.

- The lack of transparency regarding the extension's purpose and the developer's identity raises questions about the extension's legitimacy.

Recommendations:

- Exercise caution when installing this extension, as it poses a high risk to your security and privacy.

- If you decide to use the extension, consider running it in a separate Chrome profile or a sandboxed environment to minimize potential risks.

- Regularly review the extension's permissions and activity, and uninstall it if you notice any suspicious behavior.

- Look for alternative extensions from reputable developers that offer similar functionality but with fewer permissions and better transparency.
