History

Historical Context

The Ninth Circuit’s 2012 United v. Nosal decision held that merely violating an employer’s use policy does not constitute “exceeding authorized access” under the CFAA; Nosal later served one year and one day in prison. The Supreme Court’s 2021 Van Buren ruling and Facebook’s 2016 CFAA win further shape regulator scrutiny of AI agents that automate credential use.
