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. 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.
