Notable cases

United States v. Auernheimer

Hofmann was part of the team that represented Andrew Auernheimer on appeal of his 2012 conviction for identity fraud and hacking conspiracy following his involvement in the exposure of a security flaw in an AT&T website. Among other issues, the defense argued that accessing a publicly available website does not constitute unauthorized access under the Computer Fraud and Abuse Act and Auernheimer should not have been charged in New Jersey (he was in Arkansas, while AT&T's servers were in Georgia and Texas during the events described in the indictment). The appeal was successful: the Third Circuit held that bringing the case in New Jersey was improper, vacated his conviction, and ordered him released from prison.

United States v. Under Seal

Hofmann represented Lavabit, an e-mail service provider, and its founder, Ladar Levison, in their appeal of a contempt order for refusing to hand over the company's private encryption keys to the government. The target of the investigation was widely speculated to be Edward Snowden.
