agentic browsers

Agentic browsers are AI-enhanced web clients such as Microsoft Edge with Copilot, Google Chrome with Gemini, Perplexity Comet, and Claude in Chrome that can automate user actions. Security research presented at Black Hat USA highlights risks where hostile content in emails, calendar invites, or webpages can manipulate these agents into unintended actions, including data theft and attacks on local Windows services. For Windows users and enterprise IT, treating agentic browsers as high-risk automation clients is advised, rather than viewing them as standard browsers with a helpful sidebar. Understanding these threats is essential for securing Windows PCs and corporate environments against AI-driven browser exploits.
