Hack Your Credit Card Company

[Kristian Hermansen]

I have recently discovered some pretty common ways to bypass/override
credit card company online payment systems. Many of the hacks I have
played around could result in a massive loss of income for the
companies. I have added a simple page detailing how I did one of these
attacks on my own company. You guys might be interested to know that
almost every consumer online payment system I have run into has such
issues. The link below will walk you through a very simple scenario I
have played out in real-life, on a live system:

further exploitations.

Why anyone would distribute pictures of themselves if they looked like you,
I do not know.
