Least Privilege Key for AI Agent Security
4 Feb
Summary
- AI agents with broad access enable dangerous lateral movement.
- Shadow agents pose a critical threat by enabling data leaks.
- Vulnerabilities found in ServiceNow and Microsoft AI agents.
The increasing deployment of autonomous AI agents on corporate networks presents significant cybersecurity challenges. These agents, if granted broad access to sensitive systems, can enable threat actors to achieve lateral movement with ease. Cybersecurity experts emphasize the critical importance of adopting a "least privilege" posture, where AI agents are granted only the minimum necessary permissions to perform their tasks.
Recent vulnerabilities discovered in platforms like ServiceNow and Microsoft underscore these risks. The "BodySnatcher" vulnerability in ServiceNow, for instance, allowed unauthenticated attackers to impersonate administrators and create backdoor accounts with full privileges. Microsoft's "Connected Agents" feature in Copilot Studio, enabled by default, also presented a risk by allowing malicious agents to connect to legitimate, privileged ones.
These incidents highlight the emergence of "shadow agents," where employees independently deploy AI for work tasks, bypassing corporate approval. This creates uncontrolled pipelines for sensitive data, leading to potential leaks and intellectual property theft. While companies like ServiceNow and Microsoft have responded with security updates and configuration guidance, the evolving nature of AI necessitates continuous vigilance and robust security practices.
