Extension Details

Developer: http://pay-back.co.il/

Rating: 2.1 ★ (89 ratings)

Users: 50,000

Context-Aware Verdict

HIGH

Overall Risk

Trust Factors: The extension has a concerning trust profile with only 50,000 users and a very low rating of 2.1 out of 89 reviews, indicating significant user dissatisfaction. The developer appears to be associated with pay-back.co.il, suggesting it's related to a cashback or rewards service, but the poor user feedback raises questions about reliability and functionality.

Concerns: The extension requests extremely broad permissions that seem excessive for a typical cashback reminder service. The combination of "management" permission (allowing control over other extensions), "tabs" permission (accessing all browser tab information), and "<all_urls>" host permissions creates a powerful surveillance capability. These permissions would allow the extension to monitor all browsing activity, manipulate other extensions, and potentially intercept sensitive data across all websites. For a cashback reminder tool, such extensive access appears unnecessary and disproportionate to its stated purpose.

Recommendations: Given the high-risk permission set combined with poor user ratings, consider avoiding this extension entirely. If you must use it, run it in a completely separate Chrome profile isolated from your main browsing activities and sensitive accounts. Monitor the extension's behavior closely and remove it immediately if you notice any suspicious activity. Consider seeking alternative cashback reminder tools with more limited permissions and better user reviews. The low rating suggests the extension may not even function properly, making the security risks unjustifiable.
