'I'm Going To Prison For Arithmetic' Andrew Auernheimer aka Weev (YouTube)
Before entering the New Jersey courthouse to face his sentencing on March 18, 2013, Andrew Auernheimer (Weev) gave a short speech to the press and to his friends. Auernheimer was sentenced to 41 months in prison followed by three years supervised release.
Auernheimer revealed a security flaw in AT&T's iPad user database, allowing him to scrape the data from 114,000 iPad users. The information was later on given to a journalist. In January 2011, the FBI did an investigation and filed a criminal complaint.
Auernheimer was convicted on conspiracy to access a computer without authorization (18 U.S.C. § 1030(a)(2)(C), part of the Computer Fraud and Abuse Act of 1986) and fraud in connection with personal information (18 U.S.C. § 1028(a)(7)).
