OpenAI’s ChatGPT Atlas, Perplexity’s Comet and others have built-in chatbots and agents that can take over your tabs.

New AI browsers from OpenAI and Perplexity promise to increase user productivity, but they also come with increased security risks.

In OpenAI’s new Atlas browser, the Ask ChatGPT sidebar is moderately helpful at best. Sometimes, it’s confusingly wrong.

New research from Brave Software shows how hidden text in an image can be used to manipulate Perplexity's Comet browser.

Perplexity's Comet AI browser can easily be tricked into following malicious instructions hidden in screenshots.

OpenAI on Tuesday unveiled a free web browser that is designed to work closely with the company’s artificial intelligence technologies, including the chatbot ChatGPT. The new browser, called Atlas, is a direct challenge to tech giants like Google, Apple and Microsoft, whose browsers have long dominated the internet.

An ethical hacker demonstrated that ChatGPT Atlas is vulnerable to clipboard injection attacks. Atlas' agent mode might click on a malicious link that hijacks your clipboard without you knowing it, leading you to paste a malicious link in your browser.

OpenAI, Google—and probably others—will engage in a battle that could fundamentally change the way we use the web.
