Hacker breaks into his jail's mainframe during prison IT class

Nicholas Webber, sentenced for five years in 2011 "for masterminding a multi-million-pound internet crime site, triggered the security scare during a lesson. It is understood his actions caused ‘major panic’ but it is not clear what, if anything, he managed to access." His illegal site, GhostMarket, had sold details from stolen credit cards. A Prison Service spokesman told the Daily Mail: ‘At the time of this incident in 2011 the educational computer system at HMP Isis was a closed network. No access to personal information or wider access to the internet or other prison systems would have been possible.’
