Google Changes Gmail—New Gemini Attack Warning

Google is rolling out Gemini-powered summaries and search in Gmail to more users, expanding AI help inside the inbox.

At the same time, Google says indirect prompt injection remains a growing risk for AI systems.

Attackers can hide instructions in email content to influence Gemini’s outputs or steer user behavior.

The update boosts productivity, but it also widens the security attack surface in a widely used email product.
