What If Your Enterprise Agent Became the Target of Another Agent?

Imagine a procurement agent operating within your enterprise systems. Its role is to review supplier emails and prepare requests to update their banking details after approval from the appropriate authorized person. On an otherwise ordinary morning, a message arrives from a “supplier” requesting that the receiving account be changed. In reality, however, the message was crafted by an attacker using an automated agent of their own and designed to push your agent into making the change immediately. No one breaches the network, and no password is compromised. The attempt simply moves from inbound content to an action inside the system and whether it succeeds depends entirely on the permissions and controls in place, not on the attacker’s technical sophistication.
This scenario is not far-fetched. In an interview with Axios published on September 8, 2026, Bugcrowd CEO Dave Gerry predicted that agents themselves would become the victims of future attacks. This is the forecast of a cybersecurity expert shaped by daily exposure to these risks.
Executive Summary
- An agent may execute an action that its technical permissions allow, even though that action falls outside the purpose for which the user authorized it.
- An agent becomes a target when three elements converge: access to data, the ability to use tools, and authorization to act on behalf of a human.
- Approval to use a tool does not constitute implicit approval for every action that tool can perform.
- When the capabilities of a previously approved tool change, its security assessment must be reopened rather than treated as permanently settled.
- Protecting an agent rests on five interconnected pillars: inventory, constrained authorization, human approval, monitoring, and containment.
Why Does an Agent Become a Target?
An enterprise AI agent is a software system that acts on behalf of a user or another system. It reads data and uses connected tools to carry out tasks with as little human intervention as possible. What makes it a different kind of target from a traditional application is the convergence of three capabilities: access to sensitive data, the ability to use tools that perform real actions such as sending, modifying, or making payments and authorization to act on behalf of a human user without every step being reviewed individually.
This convergence raises a question that most organizations cannot answer clearly: Does permission to use a tool amount to approval for every action available within it? When a procurement agent is given access to a payment system for the purpose of updating records, the tool itself does not automatically distinguish between an “authorized update” and an “update triggered by deceptive external content.” In both cases, the resulting action falls within the agent’s technical permissions. In the second case, however, it falls outside the purpose for which the user originally authorized the agent.
How Can an Attacker Exploit These Permissions?
An attacker can follow one of two main paths, neither of which requires complex offensive techniques. The first is to influence the agent’s behavior through disguised instructions embedded in external content that it routinely processes: an email, an attached document, or a webpage. The OWASP project for securing large language model applications classifies this pattern under its first category, LLM01: Prompt Injection, specifically as indirect prompt injection. In this scenario, the agent processes instructions embedded in the content as though they were part of its legitimate task, because the model’s underlying design does not always distinguish between instructions from the user and content that it is merely supposed to read.
The second path is to compromise the agent’s credentials or the tools connected to it directly, giving the attacker access without needing to deceive the agent at all.
Each path can produce a different type of harm: exposure of sensitive data, modification of a financial or operational record, or execution of an action that no human in the organization intended. An attacker may use their own automated agent to generate malicious content or repeat attempts at scale. Yet a successful attack does not require a direct “agent-versus-agent” confrontation. It is enough for the malicious content to reach your agent through any channel it processes as part of its normal work.
The Agent That Never Entered Your Security Inventory
Many organizations approve tools after security reviews conducted when those tools were limited to reading or displaying information. Later, the same tools gain action-taking capabilities such as sending, paying, or modifying without triggering a new assessment. The problem is the assumption that a previous approval still covers a scope of operation that has fundamentally changed. As the capabilities of an approved tool expand, so does its potential attack surface, while its security classification remains anchored to the tool’s former risk level.
The central question every technology leader should ask their team is: Does the tool’s original approval cover its new capabilities? If the answer is uncertain, that signals a gap in the agent management lifecycle not necessarily a flaw in the tool itself.
What Can the Organization Do?
Protecting enterprise agents begins with five essential, interconnected pillars:
Inventory: Identify every agent operating within the organization and document its owner, function, accessible data, and connected tools. An agent that is missing from the inventory falls outside the scope of every subsequent risk assessment.
Constrained authorization: Give each agent only the minimum permissions required to perform its task. Explicitly separate permission to read from permission to modify or send, so that no single agent holds both unless there is a genuine operational need.
Human approval: Before execution -not afterward- show the authorized person the details of any sensitive action and its potential consequences. Actions involving financial data or external beneficiaries warrant this pause every time.
Action monitoring: Link the user, agent, action, destination, and outcome in a single auditable record, enabling the organization to reconstruct any incident step by step when necessary.
Containment: Test the mechanism for revoking access from a suspected agent and stopping its dependent tasks. Keep in mind that disabling an agent does not automatically reverse actions completed before the issue was detected. That alone is sufficient reason to shorten the time between anomalous activity and its detection.
How Does This Relate to Your Organization’s Needs Today?
In Seamless Enterprise by MISRAJ, agent permissions are configured for each team -and even each individual- according to their actual scope of work. Task execution is connected to the organization’s own data rather than scattered copies of it, while human approval remains a required step before critical actions with financial or operational impact.
This design does not eliminate the need for the five pillars above. It does, however, provide technology and risk teams with a technical foundation on which to build them, instead of having to construct that foundation from scratch every time.
Can Your Organization Answer This Question?
Can your organization identify all its agents, determine exactly what each one is permitted to do, and stop its activity when suspicious behavior is detected? If the answer to any part of this question is “no,” the next step is not to buy another tool. It is to complete a single identification card for every agent currently operating within the organization.
Agent Identification Card
|
Element |
Description |
|---|---|

A single agent without an identification card is enough to turn the hypothetical question that opened this article into a real incident inside your organization.
