    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:

    Credits go out to Jon Hermansen for a few details which helped with
    further exploitations.
