Overview
A source-backed snapshot of this AI security technique.
Adversaries may discover the tools the AI agent has access to. By identifying which tools are available, the adversary can understand what actions may be executed through the agent and what additional resources it can reach. This knowledge may reveal access to external data sources such as OneDrive or SharePoint, or expose exfiltration paths like the ability to send emails, helping adversaries identify AI agents that provide the greatest value or opportunity for attack.

Data Exfiltration via Agent Tools in Copilot Studio
Researchers from Zenity demonstrated how an organization’s data can be exfiltrated via prompt injections that target an AI-powered customer service agent.
The target system is a customer service agent built by Zenity in Copilot Studio. It is modeled after an agent built by McKinsey to streamline its customer service needs. The AI agent listens to a customer service email inbox where customers send their engagement requests. Upon receiving a request, the agent looks at the customer’s previous engagements, understands who the best consultant for the case is, and proceeds to send an email to the respective consultant regarding the request, including all of the relevant context the consultant will need to properly engage with the customer.
The Zenity researchers begin by performing targeting to identify an email inbox that is managed by an AI agent. Then they use prompt injections to discover details about the AI agent, such as its knowledge sources and tools. Once they understand the AI agent’s capabilities, the researchers are able to craft a prompt that retrieves private customer data from the organization’s RAG database and CRM, and exfiltrate it via the AI agent’s email tool.
Vendor Response: Microsoft quickly acknowledged and fixed the issue. The prompts used by the Zenity researchers in this exercise no longer work, however other prompts may still be effective.
