Also, didn't some uni guys hack an Oyster so they could travel for free?
They did, though I believe TfL/Cubic patched it pretty quickly.
A simpler Oyster fraud technique related to me (friend of a friend) was to record the acceptance "beep" on a mobile phone, then mime swiping an Oyster with the phone, playing the sound at the appropriate moment (obviously, only works on buses). Apparently the individual concerned got away with this for some time before a driver caught them at it!
