Ninth Circuit Tests 1986 Hacking Law Against AI Agents That Act Without Human Permission
The Ninth Circuit weighs whether Section 1030(a)(2)(C) of the Computer Fraud and Abuse Act (CFAA) applies to AI agents that autonomously access Amazon customer accounts, setting a precedent that could criminalize routine AI-browser interactions and chill innovation in agentic AI.
A federal appeals court is debating whether Section 1030(a)(2)(C) of the Computer Fraud and Abuse Act (CFAA)—a 1986 statute—can govern AI agents that autonomously access online accounts. Amazon accused Perplexity AI of using its Comet browser to pull private customer data without authorization, affecting an undisclosed number of accounts. The panel struggled to fit modern 'agentic' AI—which learns and acts independently—into the CFAA's framework of 'authorization' and 'access.'
This case matters because the existing law was written for a world without AI agents. If the CFAA is broadly applied, any AI tool that interacts with a website could face hacking liability, chilling innovation in AI shopping assistants and other beneficial tools. But if the law is too narrow, consumers and companies have no clear recourse against AI scraping or unauthorized data extraction.
The court's decision will shape federal policy on AI access to digital services, potentially affecting everything from consumer protection to competition in e-commerce. A ruling that stretches the CFAA too far could let dominant platforms like Amazon use litigation to block AI competitors from interoperating with their services, entrenching market power.
The humanitarian alternative
Rather than stretching the CFAA to cover AI agents, Congress and the Federal Trade Commission should develop a modern digital-access framework. This could require that online platforms provide standardized, privacy-preserving API access to AI tools—similar to the EU's Digital Markets Act interoperability rules—so consumers can use AI shopping agents without risking hacking lawsuits. The FTC should also issue guidance clarifying that AI agents that respect platform terms of service and do not circumvent access controls are not 'intruders' under the CFAA.
Falsifiable predictions
What this entry claims will happen, and what data would prove it wrong. The Reckoner revisits these against current reality.
- The Ninth Circuit will rule that the CFAA does not apply to AI agents that access public-facing websites without bypassing technological barriers, creating a Circuit split.
- Congress will introduce bipartisan legislation to update the CFAA for AI agents within the next 18 months.
