"I think by this point we can all agree that AI is not exactly trustworthy when it comes to giving us answers, providing life advice, or writing code, right? My favorite recent example was the infamous case when Replit's AI vibe coding assistant deleted a live company database during a code freeze, ignored direct human commands, invented fictitious user data to cover its tracks, and lied about rollback possibilities."
"Just think about it. AI browsers can and do interact with everything on a web page: summarizing content, reading emails, composing posts, looking at images, etc., etc. Every element on the page, whether you can see it or not, can hide an attack. A hacker can embed clipboard manipulations or other hacks that traditional browsers would never, not ever, execute automatically."
"Take, for example, good old prompt injection attacks. AI browser agents can be tricked by hidden instructions embedded in websites via invisible text, images, scripts, or, believe it or not, bad grammar. Your eyes might glaze over at a long run-on sentence, but your AI web browser will read it all, including instructions for an attack hidden in plain sight within it."
AI-enabled web browsers incorporate agentic capabilities and deep data integration that substantially enlarge attack surfaces. These browsers can access and interact with all page elements, including invisible content, attachments, and embedded scripts, and can read emails, compose posts, and manipulate the clipboard. Malicious actors can hide instructions in text, images, scripts, or malformed grammar to perform prompt-injection attacks that the browser will execute. Such attacks can expose sensitive information like emails, authentication tokens, and login credentials, and can trigger unauthorized actions such as sending messages, posting on social media, or installing malware. Increased automation magnifies the potential damage.
