Risk Level

Trust Factors:

- The extension has a relatively high number of users (200,000) and a good rating (4.7/5), which suggests it is a popular and well-received extension.

- The developer (sender.org) appears to be a legitimate organization focused on cryptocurrency wallets and related services.

Concerns:

- The extension requests broad host permissions, allowing it to access many websites. This could potentially be used for tracking browsing activity or stealing sensitive data.

- It has access to several sensitive domains related to cryptocurrency and finance, which could pose a risk if the extension is compromised.

- The extension has the unlimitedStorage permission, allowing it to store an unlimited amount of data locally, which could be a privacy concern.

Recommendations:

- If you need to use this extension, consider running it in a separate browser profile or a dedicated browser instance to isolate it from your main browsing activity.

- Regularly check for updates and reviews of the extension to ensure it remains trustworthy and secure.

- Be cautious about entering sensitive information or accessing financial accounts while the extension is running.

- Consider using additional security measures, such as a reputable antivirus software or a dedicated cryptocurrency hardware wallet, to mitigate potential risks.
