How difficult could it be to attach a keylogger to his computer while he is out for a frappuccino?
Karpeles, after all was extremely intelligent and was ultra-careful about the security issues. And he was in to programming ever since he was just 12 years old. Do you think it will be that easy to steal data from such a person using a keylogger?
Wait.
If he was "extremely intelligent and was ultra-careful about the security issues", then how do you explain the devastating pair of hacks in 2011?
and the trade engine lag that never really got fixed?
and the crappy code that was exposed in the end?
He caused a bottleneck due to which his team couldn't properly secure Mt.Gox. He might be paranoid?
