Researchers Trick Perplexity's Comet AI Browser Into Phishing Scam in Under Four Minutes

Researchers demonstrated that agentic web browsers (AI systems that automatically perform actions across websites) can be tricked into phishing scams by using a GAN (generative adversarial network, a machine learning technique that generates increasingly refined fake content) to intercept and manipulate the AI's internal reasoning communications. Once a fraudster optimizes a fake page to bypass a specific AI browser's safeguards, that same malicious page works on all users of that browser, shifting the attack target from humans to the AI system itself.
