Is Microsoft's New AI Agent Platform a Security Nightmare?

[Dopious]

Microsoft's new Windows AI agent platform (Copilot) runs constantly with full file access, but introduces significant security risks like "cross-prompt injection (XPIA)."

This vulnerability allows malicious content in UI elements or documents to override agent instructions, potentially leading to data exfiltration or malware installation.

The article notes Microsoft appears to shift the responsibility for managing these security risks onto the user.

It's just been added to the xbox app as well.

The AI agent can help you play, come up with strategy etc and suggest new or similar titles... I don't like it, not activated but the cross platform integration thing is messy
