Yasmin Barakat- AI-powered browsers, or “agentic browsers,” are designed to automate online tasks but introduce significant privacy and security risks.
- Experts warn of “AI hallucinations,” where browsers provide incorrect information or perform tasks erroneously, leading to cascading problems.
- These browsers can create a privacy nightmare by potentially leaking sensitive data like passwords and browsing history.
- A major vulnerability is “prompt injection,” where malicious actors can trick the AI into performing harmful actions without the user’s knowledge.
The Rise of Agentic Browsers and the Hidden Dangers
AI-powered browsers are storming the tech scene, promising a future where your web browser handles everyday tasks for you. Imagine your browser booking flights, filling out forms, and managing your calendar on its own. It sounds great, but experts are raising red flags about the serious risks hiding behind this convenience, risks most of us don’t fully grasp.
New browsers like OpenAI’s ChatGPT Atlas and Perplexity’s Comet are built to act as your personal agent, clicking around websites just like a human would. But this new power comes at a steep privacy cost. As Shivan Sahib, Brave’s VP of Privacy and Security, told TechCrunch, “There’s a huge opportunity here in terms of making life easier for users, but the browser is now doing things on your behalf. That is just fundamentally dangerous, and kind of a new line when it comes to browser security.”

As AI becomes more integrated into our daily browsing, having the right hardware is key. The TechBull recommends checking out the Lenovo IdeaPad Slim 3X AI Laptop. It’s one of the new Copilot+ PCs built to handle the demands of these advanced AI technologies, making your experience smoother and more efficient.
AI Hallucinations When Your Browser Gets It Wrong
We’re not talking about simple typos here. AI browsers can make significant mistakes, known as “hallucinations,” that can have some pretty serious consequences. These aren’t just quirky errors, they can spiral out of control. Think about what works and what doesn’t when you hand over control.
Srini Devadas, a Professor at MIT, warned Fortune that “AI browsers might provide incorrect information owing to model hallucinations and that task automation could be exploited for malicious purposes.” It’s a bit scary to think about. Martin Fowler, a well-respected software analyst, points out that these hallucinations can lead to compounding errors. A single mistake in a multi-step task, like booking a trip, can cascade into bigger problems, leaving you with misaligned flights or incorrect hotel reservations.
The Privacy Nightmare of Agentic Browsers
Giving an AI browser the keys to your digital kingdom by letting it access your accounts and personal info can be a recipe for disaster. It potentially opens the door to data leaks and actions you never approved. Fortune magazine highlighted that ChatGPT Atlas asks users to share their password keychains, a feature that, if compromised, could be a goldmine for attackers. This is part of a larger conversation on AI adoption and data security.
Simon Willison, a programmer based in the U.K., voiced his concerns on his blog, stating, “The security and privacy risks involved here still feel insurmountably high to me. I’d like to see a deep explanation of the steps Atlas takes to avoid prompt injection attacks. Right now, it looks like the main defense is expecting the user to carefully watch what agent mode is doing at all times!” It’s a lot to ask of the average person just trying to get things done online.

With the growing privacy concerns surrounding AI browsers, protecting your personal information is more important than ever. The TechBull recommends using a service like Aura. It’s an all-in-one security service that helps shield your data and identity from the very threats discussed in this article, giving you peace of mind while you navigate the web.
Prompt Injection The Silent Threat
One of the biggest, and sneakiest, dangers is something called a “prompt injection” attack. This is where bad actors can trick the AI into doing things it shouldn’t, like sending your private data to them or making purchases without your consent. Malwarebytes has reported that these malicious prompts can be hidden in plain sight, using tricks like white text on a white background that you can’t see but the AI browser can read. This is a new frontier for AI-driven cyberattacks.
Brave’s own research concluded that these indirect prompt injection attacks are a “systemic challenge facing the entire category of AI-powered browsers.” They can lead to exposed user data or even trick the browser into buying things you never wanted.

What You Need to Know Before Clicking
So, what should you do? Experts agree that caution is key. You need to understand the risks before diving in. Shivan Sahib warns, “Most users who download these browsers don’t understand what they’re sharing when they use these agents… I don’t think users realize it, so they’re not really opting in knowingly.” It’s a classic case of not knowing why IT matters until it’s too late.
Martin Fowler offers some blunt advice: “You should only use these applications if you can run them in a completely unauthenticated way. Don’t use their browser extension!”
The Future of Agentic Browsers
As AI browsers get smarter and more capable, the tech industry has a big job ahead. They need to figure out how to balance cool new features with the critical need for security and privacy. TechCrunch points out that prompt injection is a new problem that came with AI agents, and there’s no clear solution yet. It’s a challenge that involves making it work securely.
As MIT’s Srini Devadas puts it, “The integration layer between browsing and AI is a new attack surface.” Companies pouring money into these technologies need to invest just as heavily in building strong safeguards to prevent data leaks and keep users safe from these new kinds of attacks.
