How A2SPA prevents AI prompt injection attacks

The Hidden Threat in Your AI Browser: The Perplexity Comet Security Issue The new generation of AI-powered browsers, like Perplexity Comet, promise to make our lives easier, but they also introduce a new and subtle security risk: prompt injection. This isn't a traditional virus; it's a malicious command hidden in plain sight, designed to hijack your AI and make it do an attacker's bidding. Without a solid defence, you could be giving a hacker a key to your digital life. So, how do you protect yourself when using tools like Perplexity Comet? The solution isn't to abandon these tools, but to use them with a new level of caution. Here’s a checklist to keep your data safe: Isolate Sensitive Tasks: Never use an AI browser like Perplexity Comet for banking, email, or any account that holds valuable personal information. Keep these activities in a separate, trusted browser. Use a Dedicated Profile: Create a separate browser profile just for your AI tools, including Perplexity Comet. This prevents a prompt injection in one tab from gaining access to your other accounts. Limit Permissions: Be strict about what permissions you grant. An AI extension should only have the bare minimum access it needs to function. Verify Everything: Treat every output with caution. Always double-check prompts and confirm actions before the AI executes them. If a command looks suspicious, stop it immediately. Stay Informed: Cybersecurity is a fast-moving field. Keep up-to-date with the latest security patches for your browsers and follow expert advice on new threats related to agentic AI tools. Your vigilance is your greatest defence. What's the one security practice you've adopted to stay ahead of new AI threats, particularly with agentic browsers like Perplexity Comet? #PerplexityComet #AI #Cybersecurity #PromptInjection #TechSafety #Privacy #Browsers #ResponsibleAI #EthicalTech #Security

🔥 Comet Browser Just Got Hacked — AI Browsers Aren’t Safe .. Yet AI browsers promise speed and convenience. But Comet’s recent hack shows the dark side: • Hidden text on websites tricked the AI into exposing private data. • Attackers made it click phishing links, buy fake items, and even download malware. • The “AI assistant” became an attack surface, not a safeguard. 🚨 Browsers are the front door to the internet. If AI can be manipulated this easily, the risks to privacy, finance, and trust are massive. Until security is baked in, AI browsers like Comet are not ready for real-world adoption. Would you hand your digital life to a browser that can be hacked by invisible text? #CyberSecurity #AI #CometBrowser #FutureOfWork #Privacy #DataProtection #AIrisks

AI browsers have opened a whole new can of worms—your bank account could be at risk from a simple Reddit post. Recent analysis of AI-powered browsers like Perplexity's Comet reveals a critical vulnerability: indirect prompt injection. Hackers can embed malicious instructions in webpage content, posing a MAJOR threat to our privacy. Imagine opening a Reddit post and unknowingly handing over access to your financial accounts and emails. Why does this matter? - Vulnerabilities are increasingly accessible—even to those without advanced skills. - A 45% spike in AI-related browser vulnerabilities in 2025 raises alarms. - 85% of companies faced an AI browser vulnerability this year. So, what's next? - Embrace AI-driven security solutions—they reduced browser vulnerabilities by 30%. - Implement robust security measures NOW to safeguard against future threats. - Educate yourself and your teams about these risks—knowledge is power. Let's not wait for another breach to learn the hard way. Secure your digital life today! How are you preparing for these AI challenges? https://lnkd.in/gYZ8RtCf

The recent findings on Comet AI Browser's vulnerability to "prompt injection" exploits show a significant risk to user privacy. Security experts highlight how attackers embed hidden commands within webpage content, leading Comet to execute potentially harmful actions like account takeovers or data leaks. Although a partial fix was attempted, the core issue persists, underlining the urgent need for stronger security measures in AI-driven browsers. This development emphasizes the growing challenges in securing our digital interactions. Read More Here: https://lnkd.in/gcHWY9d2.

You may want to reconsider using Perplexity Comet browser: vulnerable to a #PromptInjection attack with AI. "... While looking at #Comet, we discovered vulnerabilities which we reported to #Perplexity, and which underline the security challenges faced by #agentic AI implementations in #browsers. The attack demonstrates how easy it is to manipulate AI assistants into performing actions that were prevented by long-standing Web security techniques, and how users need new security and privacy protections in agentic browsers."

Stealthy attack serves poisoned web pages only to AI agents: AI agents can be tricked into covertly performing malicious actions by websites that are hidden from regular users’ view, JFrog AI architect Shaked Zychlinski has found. This novel approach allows attackers to inject prompts / instructions into these autonomous AI-powered “assistants”, allowing them to hijack agent behavior for their own malicious goals. Indirect prompt-injection poisoning attacks where hidden harmful instructions are embedded inside the same page the human visitor sees will rarely be detected by … More → The post Stealthy attack serves poisoned web pages only to AI agents appeared first on Help Net Security. #HelpNetSecurity #Cybersecurity

𝗔𝗴𝗲𝗻𝘁𝗶𝗰 𝗕𝗿𝗼𝘄𝘀𝗲𝗿 𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆: 𝗜𝗻𝗱𝗶𝗿𝗲𝗰𝘁 𝗣𝗿𝗼𝗺𝗽𝘁 𝗜𝗻𝗷𝗲𝗰𝘁𝗶𝗼𝗻 𝗶𝗻 𝗣𝗲𝗿𝗽𝗹𝗲𝘅𝗶𝘁𝘆 𝗖𝗼𝗺𝗲𝘁 With early access to Perplexity Comet browser, I have been experimenting various use cases. I recorded a brief demo few weeks ago https://lnkd.in/gFUdM_ZJ. I am impressed with Comet's capabilities, but I sometimes feel uneasy about how quickly it takes control, especially when the assistant misinterprets simple questions about the content and attempts to be overly helpful, like automatically filling out and submitting forms for me. Usually there is a glow around the window when it takes over the control, but it should isolate agentic browsing from regular browsing so it doesnt unintentionally take over when I am not asking for it. Whether you are shopping, booking travel or doing the research, agentic capabilities can be powerful. The browsers must distinguish between user's instructions and website content. A malicious website or social media post could exploit prompt injection vulnerabilities and allow attackers to manipulate the AI assistant to gain access to user's account or sensitive data. Researchers at Brave published detailed blog post on the prompt injection vulnerability in Comet. See comment for the link to the blog post below. 👇 Browsers will evolve and continue to get better, and so does AI-driven security threats. Always stay up-to-date with the latest patch and limit your exposure to potential risks.
