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

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

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

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.

OpenAI has its work cut out to justify the existence of its newfangled ChatGPT Atlas browser. It's extremely slow and vulnerable to exploits.

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

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.

What SquareX discovered are malicious extensions that can spoof the legitimate AI sidebars people use for queries. Their goal is to trick users into going to malicious websites, running data exfiltration commands, or installing backdoors. AI sidebar spoofing even works on the just-released OpenAI Atlas browser, SquareX says.
