“AI is neither good nor bad. It’s a tool, its impact depends on how we use it.” – Yoshua Bengio, pioneers of modern artificial intelligence and deep learning
Hidden threats in AI-powered browsers
As AI browsers like Perplexity’s Comet and Fellou grow in use, cybersecurity experts warn that they may be vulnerable to hidden “prompt injections.” These are malicious instructions embedded within web content that can trick the AI into leaking sensitive data or performing unintended actions. Experts caution that such flaws, if left unchecked, can turn an AI browser into a serious data security risk.
When convenience becomes compromise
AI browsers simplify how users interact with content by summarizing, analyzing, and even automating web tasks. But this convenience also introduces new attack surfaces. Visibility breaks down when browsers process SaaS dashboards or AI assistants, creating systemic weaknesses that attackers can exploit. Prompt injections exploit how AI interprets text rather than traditional software vulnerabilities. Attackers can embed instructions in links, metadata, or webpages. When the AI interprets these, it may unknowingly execute harmful commands or share data externally.
Flaws discovered and exploited
Malicious prompts can even hide inside URLs. When a user clicks such a link, the AI may misread it as a valid command. Even browsers like Comet, which have safeguards, were shown to be bypassed by encoding stolen data in base64 format.
Building awareness and safeguards
Experts urge developers to strengthen AI browser defenses and users to remain cautious. The fusion of natural-language processing with browsing power brings both innovation and risk. Preventing misuse begins with understanding how these systems interpret and act upon hidden cues.
Summary
AI browsers offer powerful, conversational web experiences but are exposed to hidden prompt attacks that exploit natural-language interpretation. Researchers and security experts warn that unless strong safeguards are built, these AI tools could become gateways for data breaches and misinformation.
Food for thought
As AI becomes the new interface for web browsing, can users truly trust machines that interpret every word as a command?
AI concept to learn: Prompt injection
Prompt injection is a cybersecurity vulnerability in AI systems where hidden instructions are embedded within text or code to manipulate the model’s response. It exploits the model’s tendency to follow natural-language cues without verifying intent or source authenticity.
