A word that has been very much in the news of late is “hacking”. Away from the seedy world of unscrupulous journalists breaking into celebrity voicemail accounts, hacking is an everyday occurrence on the web. Some big names have been hit over the last year. Adobe recently had to inform no less than 38 million of its active users that account usernames and passwords had been stolen from their systems. Others who have been infiltrated include Facebook, Microsoft, Apple, the New York Times, and the US broadcaster NBC.
