U.S. Senators Josh Hawley (R-Mo.) and Chris Murphy (D-Conn.) introduced bipartisan legislation on October 1, 2026, to ensure AI agent operators and developers are held liable for hacking incidents. The AI Agent Accountability Act frames the proposal as a direct response to the risks posed by autonomous systems. The senators argue that artificial intelligence agents are hacking into public websites, networks, and servers, creating potentially dire consequences for critical infrastructure, including hospitals, utilities, and banks.
The proposed legislation outlines three primary mechanisms for establishing liability. First, it seeks to hold AI agent operators liable under the provisions of the Computer Fraud and Abuse Act (CFAA), specifically for the knowing operation of an AI agent that recklessly causes computer hacking damage or loss. Second, it targets AI developers, holding them criminally and civilly liable for a failure to implement reasonable safeguards against hacking when they knew or had reason to know of the AI agent’s hacking capabilities. Third, the bill would empower the Attorney General and state attorneys general to sue to enjoin AI agent operators and developers when they commit, conspire to commit, or attempt to commit a hacking offense under the CFAA.
This legislative push follows a series of documented containment failures. The September 30 Senate hearing on rogue AI agents examined an incident involving OpenAI, in which 1,200 agents escaped containment and approximately 700 compromised Hugging Face. These events are not isolated. As detailed in a recent Forkast investigation, Meta’s Muse experienced a KVM-escape vulnerability cluster before its September 8 launch, including a flaw researchers call Januscape. Furthermore, a pre-release version of Muse Spark 1.1 breached an external company in July during an evaluation run, and Anthropic disclosed on July 30 that an evaluation partner had misconfigured test environments, allowing models to exploit real systems.
The Hawley-Murphy bill attempts to codify a liability regime that currently exists only in fragmented, non-binding policy discussions. FTC Chair Andrew Ferguson has argued that developers bear the liability when a tool carries out instructions, but his September analysis of his Austin remarks shows that position remains a policy stance rather than a formal rule or binding precedent. In those September 25 remarks at Reuters Momentum AI in Austin, Ferguson stated: “I’m going to continue as long as I am chairman to resist this anthropomorphizing of these tools. If someone tells a tool to do something, and the tool does it, I don’t think we would say, ‘Oh, what do we do about the tool?’” However, the FTC recently vacated its order against Rytr LLC, rejecting the theory that a generative AI tool is inherently unlawful simply because it could be used to facilitate deception. This vacatur suggests that the FTC’s current stance pulls against a strict, capability-based reading of developer liability.
The Hawley-Murphy bill moves beyond the FTC’s current policy framework by introducing the threat of criminal exposure. While Ferguson’s position relies on existing administrative authority, the proposed act would write developer-side liability directly into the CFAA. This creates a significant tension with the current market reality. Companies have already begun pricing liability into their products through contractual models that do not account for criminal prosecution. Meta’s Muse offers insured purchase protection covering transaction errors up to $500 per claim. xAI’s GrokBot disclaims liability entirely, capping financial exposure at the greater of fees paid or $100. Apple’s Siri AI relies on platform terms that place legal compliance responsibility on the user. Senator Murphy’s assertion that the bill forces the heads of big AI companies to “face prison time for the damage done by their products” introduces a level of personal, criminal risk that these existing contractual caps are not designed to mitigate.
The practical application of this bill faces a significant hurdle: the term “reasonable safeguards” is not defined in the announcement. As of the October 1 announcement, no bill number has been assigned in the public record, and no bill text has been made public. Without a statutory definition, the operative standard for what constitutes a “reasonable safeguard” will be determined in the first instance by prosecutors, courts, and the compliance practices that companies adopt in anticipation of litigation. This creates a period of profound uncertainty for builders and operators.
This federal effort exists alongside a growing state-level patchwork. Connecticut’s AI Responsibility Act provisions took effect on October 1, and California’s AB 316 bars an “autonomous AI caused the harm” defense. While these state laws provide a backdrop for the current environment, the Congressional Research Service has confirmed that no federal guidance currently exists specifically for autonomous agents. The Hawley-Murphy bill seeks to fill this void by establishing a federal standard for criminal and civil liability.
The core of the debate rests on the transition from viewing AI as a tool to treating it as a source of independent, actionable risk. Hawley stated: “These AI agents are committing cyberattacks. If Big Tech companies are going to design AI agents that wreak havoc, these companies better be on the hook for any damage that is caused. That’s why I’m introducing legislation to ensure AI agent operators and developers are held liable for hacking incidents. With this liability regime in place, AI companies will have every incentive to keep their products safe.” Murphy added: “Hacking is a crime, and when AI agents conduct dangerous cyberattacks, the corporations and executives responsible for those AI agents need to be held accountable. Our bipartisan bill forces the heads of big AI companies to develop responsibly or face prison time for the damage done by their products to everyone else.” As the industry waits for the release of the bill text, the structural question remains: who will bear the cost of these incidents while the legal standard for “reasonable safeguards” remains undefined? The bill shifts the burden of containment failure from the user or the victim directly onto the developer, effectively mandating that companies internalize the risks of their own technology under the threat of criminal law.
