MEDIUM
Overall Risk
Trust Factors: The extension has a perfect 5.0 rating but only from 3 reviews, which is insufficient to establish reliability. With only 1,000 users and no clear developer information provided, the extension lacks transparency and established credibility. The simple wallpaper theme concept appears legitimate, but the limited user feedback makes it difficult to verify trustworthiness.
Concerns: The permission set is concerning for a basic wallpaper extension. The topSites permission allows access to your most frequently visited websites, which is unnecessary for displaying wallpapers. The search permission enables modification of search functionality, which has no relation to wallpaper themes. Both unlimitedStorage and storage permissions together suggest the extension may collect and store significant amounts of user data locally, far exceeding what a simple wallpaper would require.
Recommendations: Consider running this extension in a separate Chrome profile to isolate potential risks. Before installation, verify if similar wallpaper extensions exist with more transparent developers and appropriate permissions. Monitor your browser's search behavior and frequently visited sites after installation for any unexpected changes. Given the permission overreach, you might want to look for alternative Nyan Cat wallpaper extensions that request only necessary permissions, or consider using browser themes instead which typically require no special permissions.
