The Ninth Circuit's CFAA Ruling in Amazon v. Perplexity
|
|
|
While I was at Black Hat and BSides, the appeals court vacated Amazon's injunction against Perplexity's Comet browser. However, the reasoning turns on a narrow technical question: who actually "accesses" a website when an AI agent does the clicking. Back in March 2026, a district court granted Amazon a preliminary injunction barring Perplexity's Comet browser and its AI "Assistant" from …
