In the last year or so, artificial intelligence companies have rolled out a spate of web browsers equipped with\u00a0AI agents. A user might ask one of these agents to plan a vacation and it will open browser tabs to research routes and restaurants, then make reservations and add events to the user\u2019s calendar.\u00a0How well it does any of this varies.<\/p>\n

New research from the University of Washington found that the most powerful of these browsers also open users up to significant cybersecurity risks. A UW team studied seven popular agentic browsers and found that four create ways for malicious actors to bypass a fundamental cybersecurity protocol called the \u201csame-origin policy,\u201d which makes websites that are open in a browser unable to interact with each other\u2019s information.<\/p>\n

Researchers ran a successful proof-of-concept cyberattack on one browser, ChatGPT Atlas. They had a website steal information from another that was embedded in it \u2014 as if an ad on an email site could snatch sensitive info from the user\u2019s emails. Researchers also found the right conditions for similar attacks in three other browsers: Chrome with Gemini, Claude for Chrome and Perplexity Comet. The browsers that gave agents fewer permissions were generally safer.\u00a0<\/p>\n

\u201cBrowser agents aren\u2019t ready for the public,\u201d said co-senior author\u00a0David Kohlbrenner, a UW assistant professor in the Paul G. Allen School of Computer Science & Engineering. \u201cEven if you\u2019re a relatively savvy user, if these agents have access to a browser that contains your credentials \u2014 your email, your bank account, whatever it is \u2014 you should not trust that these systems are ready to truly protect your information. They may get there in time, but they\u2019re not there yet.\u201d\u00a0<\/p>\n

The team\u00a0presented its research\u00a0April 26 at the Agents in the Wild Workshop in Rio de Janeiro.\u00a0<\/p>\n
