Excerpts from a superb article about Kevin Mitnick ‘Computer terrorist’ teaches anti-hacking (from CNN):
He can find George Bush senior’s social security number and Leonardo DiCaprio’s mother’s maiden name in under 15 seconds, and led the FBI on a three-year manhunt as he hacked his way into the world’s biggest firms. …
He argues that while sophisticated technology can help keep networks clean from viruses, it is useless if hackers can con a company’s employees into handing over passwords by posing, for example, as colleagues.
And you thought it was all about SSL, PGP, etc.
