Subject: what a web page can make your AI browser do

Hi [first name],

AI browsers act with your logins, and a web page can hide instructions for them. In 2025
researchers showed hidden comments making AI browsers read email and leak sign-in codes. Browser Agent
Firewall checks every action against the task and stops the hijacked ones.
