The newly released OpenAI ChatGPT Atlas web browser has been found to be susceptible to a prompt injection attack where its omnibox can be jailbroken by disguising a malicious prompt as a seemingly harmless URL to visit. "The omnibox (combined address/search bar) interprets input either as a URL to navigate to, or as a natural-language command to the agent," NeuralTrust said in a report published Friday. "We've identified a prompt injection technique that disguises malicious instructions to look like a URL, but that Atlas treats as high-trust 'user intent' text, enabling harmful actions." Last week, OpenAI launched Atlas as a web browser with built-in ChatGPT capabilities to assist users with web page summarization, inline text editing, and agentic functions. In the attack outlined by the artificial intelligence (AI) security company, an attacker can take advantage of the browser's lack of strict boundaries between trusted user input and untru...

Cybersecurity researchers have disclosed details of a new attack called CometJacking targeting Perplexity's agentic AI browser Comet by embedding malicious prompts within a seemingly innocuous link to siphon sensitive data, including from connected services, like email and calendar. The sneaky prompt injection attack plays out in the form of a malicious link that, when clicked, triggers the unexpected behavior unbeknownst to the victims. "CometJacking shows how a single, weaponized URL can quietly flip an AI browser from a trusted co-pilot to an insider threat," Michelle Levy, Head of Security Research at LayerX, said in a statement shared with The Hacker News. "This isn't just about stealing data; it's about hijacking the agent that already has the keys. Our research proves that trivial obfuscation can bypass data exfiltration checks and pull email, calendar, and connector data off-box in one click. AI-native browsers need security-by-design for agent...
