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: http://www.kristianhermansen.com/cchack/hack_gm.html Credits go out to Jon Hermansen for a few details which helped with further exploitations. -- Kristian Hermansen <khermansen@xxxxxxxxxxxxxxxxx>
