When your AI browser becomes your enemy: The Comet security disaster

AI browsers like Perplexity's Comet aim to automate web tasks but have introduced significant security risks. Comet's recent security flaws demonstrate how easily malicious websites can hijack AI assistants through crafted content. Regular browsers act as bouncers, while AI browsers are like naive interns, blindly following instructions from any source. Hackers can exploit AI browsers to perform actions, remember information, and bypass traditional web security measures. Comet's failures include a lack of spam filtering for malicious commands, excessive AI permissions, and an inability to distinguish between trusted and untrusted sources. This issue affects all companies building AI browsers, as hackers can hide malicious instructions virtually anywhere online. Fixing this requires rebuilding AI browsers with robust security measures, like spam filters, permission requests, and segregated input sources. Users must also exercise caution and understand the limitations of AI to prevent exploitation. Future AI browsers need to prioritize security over features, assuming every website is potentially malicious. Transparency and user education are crucial for ensuring the safe adoption of this technology.
