Comet Browser, developed by Perplexity AI, offers AI-powered features and is considered safe in terms of having built-in ad blockers and local data storage, making it more private than mainstream browsers like Chrome. However, it has notable security vulnerabilities related to how it processes web content, particularly prompt injection attacks where malicious instructions embedded in web pages can be executed by the browser's AI. These vulnerabilities allow attackers to potentially access sensitive user data such as emails, OTPs, and calendar information without user interaction. Despite efforts to fix these issues, Comet still has security gaps that could expose users to phishing scams and data theft. In summary, while Comet Browser has useful AI-driven features and some privacy advantages, it carries significant security risks due to prompt injection attacks and vulnerabilities that have been demonstrated by security researchers. Users should be cautious and consider alternatives if prioritizing robust online security and privacy.
