Joshua Horowitz's practice is concentrated on litigation matters requiring expertise in technology and computer software. He has served as the technology lawyer on the defense team of multiple federal cybercrime cases in the Southern District of New York, including the Silk Road trial (United States v. Ulbricht) and other international cybercrime matters. He also represents corporate clients in government investigations involving technologically complex legal issues. In the Silk Road case, he submitted an 18-page declaration undermining technical assertions made by the FBI with regard to their discovery of computer servers located abroad. His work raised significant questions about the government's purported methodology in uncovering computer servers hosted as a Tor hidden service, receiving national recognition in Forbes, Wired, TechCrunch, Ars Technica, and other publications. While in law school, Joshua worked at the Software Freedom Law Center, an organization providing legal counsel to Free and Open Source (FOSS) software developers in a broad variety of legal matters. He received his BA from the University of Rochester and JD from Ohio Northern University and launched his practice immediately upon graduating from law school.
