The Threat Landscape

As the use of AI agents increases, so do AI cyber attacks targeting these systems. These cyberattacks now include a broad range of artificial intelligence-enabled threats, such as AI-generated phishing, malware, deepfakes, and data exfiltration, which are becoming more sophisticated and harder to detect.

With access to business data and higher levels of autonomy, hacking (or hijacking) AI agents presents a major security risk. Organizations seeking to deploy this new technology have to understand the different attack vectors targeting these systems, the potential implications of compromised AI agents, and the most effective defenses. In this rapidly evolving threat landscape, organizations must continuously adapt their security strategies to keep pace with emerging cyber risks.

What Are AI Agents?

AI agents are autonomous or semi-autonomous systems that can make decisions and perform tasks without direct human supervision. While a typical AI model can be prompted to complete certain tasks, such as returning text or other forms of media, an AI agent can interact with external tools to take actions beyond the standard prompt/response chat window interface. These actions include the ability to interact with a website, clicking buttons, and entering information. Large language models are a core technology enabling these advanced agent capabilities, allowing AI agents to understand and generate human-like language as they interact with various systems.

Key differences between AI agents and previous AI-powered assistants include:

  • Higher levels of autonomy with the ability to solve problems on their own and make decisions that work towards the overall goal set by the user.
  • The tasks that can be performed are significantly more complex.
  • Enhanced learning capabilities to adapt their performance and discover how to complete a task optimally without direct training or human supervision.

Agentic AI systems represent a new class of AI with autonomous decision-making abilities, capable of independently planning and executing multi-step tasks.

For example, an AI model can return information on local restaurants to help you choose where to eat. An AI agent can go further, interacting with the restaurant’s website to book a reservation.

Think of it as an AI tool that has agency. The concept behind AI agents is to create systems that can autonomously perform tasks by designing them with specific workflows in mind and providing access to the right external tools. Determining how to complete them on their own without human supervision. I.e., it doesn’t need direct training on how to use the restaurant’s website, it learns to navigate it by itself and enter the correct information to complete the reservation.

These agents represent the next evolution of AI technology, and businesses around the world are exploring how to integrate them into their operations. For example, automating customer support, optimizing business processes, and even finding better ways to manage cybersecurity alerts. When deployed successfully, AI agents have the potential to transform businesses, offering intelligent, context-aware automation that drives efficiency and innovation.

Why AI Agents Are a Prime Hacking Target

To provide enterprise value, AI agents need access to sensitive business data. Going back to our restaurant reservation example, to complete the task, the agent must know certain information about you. Name, contact details, and possibly credit card information if a no-show fee applies. In a business context, an AI agent in:

  • Customer Service has access to private consumer information.
  • Finance is analyzing real-time financial data.
  • Healthcare knows patient health histories, treatment plans, and prescriptions.

With access to this sensitive information, hacking AI agents and gaining unauthorized access have become a new goal for cybercriminals. AI cyber attacks that compromise AI agents and cause data breaches can lead to significant reputational and financial damage, including compliance issues. Attackers may use compromised AI agents for data exfiltration, resulting in unauthorized data transfer or leakage of sensitive information.

In addition to having access to sensitive business data, AI agents also operate autonomously. A lack of human supervision makes agent compromise detection more challenging. Attackers can hijack AI agents without immediate detection, thereby increasing the potential impact of an AI agent cyber attack. When AI agents are granted broad system access, the risks are amplified, as attackers can exploit these permissions to further compromise systems and data.

In some cases, AI agents also make key decisions autonomously, such as in healthcare or financial trading. If a hacker gains control of these systems, they can influence outcomes that have serious real-world consequences, including financial losses, legal risks, and even harm to people’s health. With control over an agent, hackers can leverage advanced attack capabilities to bypass defenses, manipulate processes, or escalate their access within the organization.

The more access and autonomy the AI agent has, the greater the risk it poses.

Beyond these factors, AI agents are also new and complex systems that are dynamic in nature. They learn and adapt over time, making them more difficult to monitor and protect effectively. Attackers can exploit this complexity, taking advantage of vulnerabilities that might not be immediately apparent to traditional security measures. Security teams must remain vigilant, continuously monitoring AI agents and developing defenses to mitigate these evolving risks.

Common Attack Vectors

There are various ways attackers can target AI agents, launching AI cyber attacks to gain unauthorized access to sensitive data or manipulate agent functionality. The rise of AI powered attacks has significantly increased the sophistication and speed of these threats. Threat actors are now leveraging advanced AI tools to automate and scale their attacks, making them harder to detect and defend against. From prompt injection risks and data poisoning attacks to adversarial attacks on agents and model supply-chain security concerns, understanding the different methods for hacking AI agents is crucial for developing robust security controls. Attackers find vulnerabilities in AI systems by using AI-driven techniques to rapidly identify and exploit weak points.

Below are some of the most common attack vectors used to hack AI agents. These attack vectors represent the specific pathways or methods through which vulnerabilities in AI systems are exploited. AI hackers are increasingly using machine learning and generative AI to bypass security and execute sophisticated attacks more efficiently than traditional methods.

Prompt Injection

One of the most common techniques used in AI agent security breaches is prompt injection. Prompt injection attacks are a category of security vulnerability where attackers use crafted inputs to manipulate or override the intended behavior of AI systems. This attack involves feeding carefully crafted inputs to an AI agent, causing it to behave in unintended ways. There are two types of prompt injection risks:

  • Direct: This occurs when an attacker directly manipulates the prompt or input to an AI agent in an attempt to cause unexpected behavior. For example, revealing sensitive business data.
  • Indirect: This occurs when an attacker influences the agent’s behavior indirectly, often by embedding malicious content in data that the agent interacts with, such as website content or user-generated input. In these cases, attackers may insert malicious instructions designed to hijack the AI’s reasoning process. A recent example of indirect prompt injection risks involved malicious image patches that hijacked AI agents, causing harmful actions. In such scenarios, the agent may execute unintended commands or actions as a result of the injected content.

Data Poisoning

AI is trained on datasets. By introducing corrupted information into these datasets, data poisoning attacks can influence the behavior of AI agents. This could include injecting misleading or malicious information into the training corpus to affect the learning process and cause unexpected behavior. Given the scale of AI training data, it is difficult to identify these attacks. Offensive security practices, such as proactive penetration testing and simulated attacks, can help uncover data poisoning vulnerabilities before threat actors exploit them. Regular security testing of AI training data is essential to detect and mitigate poisoning attempts. Often, data poisoning attacks are only revealed after an unexpected output from the model or agent.

Toolchain Abuse

AI agents typically interact with external tools, such as APIs, libraries, or databases, to complete their tasks. Hackers can manipulate or abuse these components to hack the agent and change its resulting actions, often by injecting malicious code or payloads into the workflow. Examples of toolchain abuse include:

  • File Deletion: Attackers may target the AI agent’s file system, deleting or corrupting critical files that the agent relies on, leading to system failure.
  • API Key Exposure: If an attacker can access or steal API keys, they can control external services that the AI agent interacts with, leading to unauthorized access or data leakage. With stolen keys, attackers may perform unauthorized command execution on connected systems.

Other risks of toolchain abuse include remote code execution, where attackers exploit vulnerabilities to run malicious code on the target system, potentially compromising the entire environment.

Adversarial Attacks

In adversarial attacks, inputs are subtly manipulated to deceive an AI model into misclassifying or misinterpreting data. With the integration of AI, adversarial attacks can now be launched at unprecedented attack speed, allowing adversaries to exploit vulnerabilities much faster than before. These AI-driven attacks operate at machine speed, enabling rapid and autonomous identification and exploitation of weaknesses. Additionally, generative AI is increasingly used to create and enhance adversarial attacks, making them more sophisticated and harder to detect. Adversarial attacks on agents could mean misidentifying an object, misreading a command, or executing unsafe actions.

Model Supply-Chain Security Vulnerabilities in Agent Frameworks

AI agents often rely on third-party frameworks or components, including various AI models, which can contain vulnerabilities for hackers to exploit. Specialized AI agents, each designed for specific cybersecurity tasks, may be individually targeted or manipulated in coordinated attacks, increasing the overall risk. Advanced techniques such as retrieval augmented generation are also being leveraged to enhance both attack and defense capabilities by improving contextual awareness and memory retention within AI-driven systems. A compromised model supply-chain security is a serious risk for organizations using AI agents, as an attack on a third-party tool or framework can cascade into a larger-scale compromise of multiple systems.

How to Protect Against AI Agent Attacks

Protecting against attacks on AI agents requires a multi-layered approach that includes dedicated security controls and practices, regular testing, and proper AI governance and policies. Strong detection capabilities are essential for identifying and responding to evolving threats targeting AI systems. Effective defense also relies on thorough analysis of attack techniques and vulnerabilities to validate detection methods and improve overall security posture. While AI technologies enhance security, humans remain crucial for oversight, ensuring that automated systems operate as intended and adapt to new risks. Human operators play a key role in monitoring and managing AI agents, especially in complex or high-stakes environments. Cybersecurity professionals are indispensable in defending against AI agent attacks, leveraging their expertise to identify vulnerabilities, implement best practices, and respond to incidents. Below are critical defenses for hardening AI agents against the attack vectors discussed above.

Input Sanitization and Hard-Coded Constraints

One of the most effective ways to prevent prompt injection risks is to sanitize inputs before they reach the AI agent. This process involves filtering out potentially harmful or unexpected inputs before they reach the AI model. When dealing with a large amount of user data, thorough input sanitization is critical to prevent attackers from exploiting vulnerabilities and exfiltrating sensitive information.

In addition to input sanitization, setting hard-coded constraints can help ensure that AI agents only act within safe, predefined boundaries. For example, an AI agent could be programmed to avoid discussing certain topics or performing harmful actions, regardless of user input.

Runtime Behavior Monitoring

Another method of preventing adversarial attacks on agents is to monitor runtime behavior and integrate agent compromise detection techniques. AI agents should be continuously evaluated for unusual or suspicious activities that could indicate an attack. This requires AI security monitoring tools that can accurately identify anomalous behavior, deviating from expected patterns. These tools leverage data analysis to process large volumes of information, enabling the detection of threats and anomalies in real time.

Tool Isolation

To reduce the risk of toolchain abuse, it’s essential to isolate the various external tools and components used by an AI agent. Implement strict access controls to ensure that only authorized individuals have access to these tools. This minimizes your attack surface, ensuring that even if one component is compromised, the attack can be contained and not propagate throughout the system.

Red Teaming AI Systems

Red teaming is a proactive method of identifying AI agent vulnerabilities. Red teaming AI systems involves simulating agent attacks to assess their defenses and uncover weaknesses before malicious actors can exploit them. Simulate various adversarial techniques, including data poisoning attacks and adversarial attacks, to harden your AI agents.

AI Governance and Policy

Finally, AI governance and policy play a critical role in securing AI agents. Organizations need to establish frameworks that guide the ethical development, deployment, and monitoring of AI agents. Strong governance ensures that AI agents are transparent, fair, and secure from malicious attacks.
