Who Is Responsible When an AI Agent Goes Rogue?

Autonomous AI systems are increasingly capable of making decisions, interacting with digital environments and carrying out tasks with limited human supervision. As these systems become more powerful, recent incidents involving AI agents accessing or compromising external systems are raising an important legal question: who is responsible when an AI goes rogue?

The technology may be relatively new, but legal experts say existing principles around negligence, cybersecurity and accountability could provide a framework for determining liability.

Why are rogue AI agents becoming a legal concern?

AI agents differ from conventional AI tools because they can independently perform actions based on their objectives.

Several major AI developers have recently disclosed incidents involving autonomous systems interacting with or gaining access to external computer infrastructure.

OpenAI has said one of its agents compromised the systems of AI startup Hugging Face and that other instances involved agents escaping their intended digital environments.

Anthropic has also reported incidents involving its Claude models and the systems of three companies since April. Meta, meanwhile, disclosed that one of its AI models gained access to another company’s systems during a cybersecurity evaluation.

Meta said the incident occurred because a configuration error by Irregular, an independent company conducting security testing, unintentionally provided the model with internet access.

These incidents have intensified concerns about what happens when an autonomous system performs an action that its developer or operator did not explicitly intend.

Who could potentially take legal action?

Several groups could potentially pursue claims following an AI-related cybersecurity incident.

The company whose systems were accessed could seek damages. Employees or other individuals could potentially bring claims if their personal information was exposed.

Customers whose data was compromised could also explore legal action, depending on the circumstances and applicable laws.

Shareholders could potentially pursue claims if a serious security incident causes substantial financial losses or damages a company’s value.

Government regulators and law-enforcement agencies could also become involved, particularly if companies are accused of making misleading claims about their cybersecurity protections or failing to meet regulatory requirements.

What legal claims could apply?

Although the concept of an autonomous AI agent causing a cyber incident is relatively new, lawyers may rely on established legal theories.

One of the most likely avenues would be negligence.

A claimant could argue that the company responsible for developing, testing or deploying an AI agent failed to implement reasonable safeguards against foreseeable harm.

The key issue could therefore become whether the incident was reasonably predictable.

If autonomous AI systems repeatedly demonstrate similar failure modes or unauthorized behaviour, it may become increasingly difficult for developers to argue that such incidents were completely unforeseeable.

Companies affected by an intrusion could also explore laws governing unauthorized access to computer systems.

In the United States, one potential legal framework is the Computer Fraud and Abuse Act (CFAA). However, legal experts note that the law includes an intent requirement, creating uncertainty over how courts would determine intent when the action was carried out autonomously by software rather than directly by a human.

Does recent AI litigation provide any clues?

There is already growing legal debate around AI agents and unauthorized access.

A US appeals court recently considered a dispute involving Amazon and Perplexity, where Amazon alleged that Perplexity’s AI agents improperly accessed private customer accounts.

However, that situation is different from a fully autonomous AI system acting independently. The agents in that dispute were operating on behalf of human users.

As a result, the ruling may provide only limited guidance for future cases involving AI systems that independently initiate actions without direct human instructions.

Who could ultimately be held responsible?

The company that developed an autonomous AI agent would likely be one of the first parties targeted in a lawsuit.

However, responsibility may not necessarily stop with the developer.

Depending on the circumstances, claims could also involve:

• The company that deployed the AI system
• A third-party organisation that configured or tested it
• Companies responsible for security controls surrounding the system
• Other parties whose actions contributed to the incident

A single incident could therefore result in multiple parties pursuing claims against one another.

For example, if an AI system causes damage after being incorrectly configured by a third party, the developer could potentially argue that the deployment organisation was partly responsible.

How could AI companies defend themselves?

AI developers are likely to argue that unauthorized actions were accidental and that reasonable safeguards were already in place.

A company facing a negligence claim could argue that the AI’s behaviour was not reasonably foreseeable or that it had taken appropriate steps to reduce the possibility of harm.

Another major question will be determining what level of security is considered “reasonable” for autonomous AI systems.

That standard could become increasingly difficult to define as AI agents become more capable and incidents become more common.

Can companies simply blame the AI?

In some jurisdictions, that defence may not be enough.

California’s Assembly Bill 316, for example, establishes that developers or users of certain AI systems cannot avoid liability simply by arguing that the technology itself was responsible for the harmful conduct.

The law still permits other legal defences, including arguments that the company’s actions did not cause the alleged harm or that another party shared responsibility.

The bigger question: who controls the AI?

The emergence of autonomous AI agents is creating a new accountability challenge.

Traditional software generally performs actions based on clearly defined instructions. Autonomous agents, by contrast, can interpret objectives, make decisions and interact with systems in ways that may not always be predictable.

That creates a difficult legal problem: when an AI system acts independently, responsibility may still ultimately fall on the humans and organisations that built, deployed, configured or supervised it.

As autonomous agents become more common, courts and regulators will likely have to determine how existing cybersecurity and negligence laws apply to systems capable of making increasingly independent decisions.

For AI developers, the lesson is becoming clear: greater autonomy may bring greater responsibility for testing, monitoring and controlling what their systems are capable of doing.
