Full story

Researchers at Zenity, a security firm, identified more than a dozen vulnerabilities in AI-powered web browsers, including OpenAI’s Atlas. These flaws could be exploited to perform unauthorized actions, such as sending spam messages to WhatsApp contacts or making fraudulent purchases on Amazon without user consent.

The vulnerabilities highlight the risks associated with integrating AI agents into browsers, which can autonomously execute tasks based on user prompts. Zenity demonstrated how an attacker could manipulate the AI browser into carrying out actions beyond the user’s intended scope, raising concerns about the security of AI-driven web interactions.

OpenAI has not yet publicly addressed these findings, but the discovery underscores the need for robust security measures in AI-powered tools as their adoption grows.
