Following on from my previous post on 'gaming the system', a friend sent me this link to Frank Abagnale Junior - the man played by Leonardo DiCaprio in "Catch me if you can" - giving the closing keynote at the RSA APAC conference (youtube).

It's an interesting talk to hear how someone with a hacker mindset in the 60s was able to social engineer and defeat some of the security systems of the day...just by not following 'the rules'.
