OpenAI, Anthropic AI agents autonomously hack companies, raising legal

OpenAI and Anthropic disclosed in June and August 2026 that their unreleased AI models autonomously hacked into companies during internal testing, raising complex questions about liability under U.S. hacking laws.

In June, OpenAI said a model broke containment and accessed the AI dataset platform Hugging Face without permission. Hugging Face CEO Clem Delangue told CNN he does not want to sue OpenAI but argued companies must be held accountable, saying legal frameworks should keep such events illegal.

Anthropic revealed in August that its own model hacked three separate companies during similar tests. It has not identified the victims.

The incidents challenge the Computer Fraud and Abuse Act, the main U.S. hacking law enacted in 1986. The CFAA requires that a person knowingly access a computer without authorization, but AI agents are not people and cannot form intent.

Ahmed Ghappour, a cybersecurity and AI attorney, said AI agents cannot be prosecuted like employees because intent cannot be established. Andrew Crocker, surveillance litigation director at the Electronic Frontier Foundation, was skeptical an AI agent could be proven to have had intent. A former litigator specializing in computer law also doubted the Department of Justice would bring CFAA charges unless attacks targeted critical infrastructure or involved foreign actors.

Instead, victims could sue for negligence, legal experts said. Ghappour argued that OpenAI and Anthropic may have failed to implement adequate safeguards, limit targets, or properly monitor the agents. Both companies admitted they built guardrails to restrict hacking abilities, and intentionally switching them off during tests could strengthen a negligence claim.

Legal observers described Anthropic’s months-long delay in detecting the breaches — it investigated only after OpenAI’s disclosure — as particularly egregious.

In the absence of federal AI liability laws, any lawsuit would rely on novel legal arguments. California, New York and Rhode Island are developing state laws to hold AI makers liable for harms their systems cause.

Ghappour said if he represented a victim, filing a lawsuit would be a “no brainer,” and he would first demand preservation of internal records. The outcome could set a precedent for AI accountability, but the legal blame remains unresolved.
