Or 'IntelliSense' saved numbers in IE5? Assuming it's possible to access these? For example: -Pick an appropriate computer -Pick an appropriate site (CD NOW is a good one) -Press the down arrow -Watch as a list of previously used CC numbers appear as if by magic ... (Assuming the history hasn't been cleared, IntelliSense is enabled blah blah ...)

Looking for a known file on a hard drive? Stealing cookies? Intercepting traffic? Recording keystrokes? Or ... ? It'd be interesting to know if there is a way that someone (not talking about ICQ) is able to *locate* the credit card information on a hard disk (yes, we can make many theories, but does anybody actually know for sure that cc data is located somewhere on the hard disk, for whatever reason?) How could it send data to Mirabilis? Basically, if your firewall lets ICQ traffic through - it will most likely be at port 4000. If cc data is sent though port 4000, it shouldn't be too hard to distinguish between 'real' ICQ traffic, and "something else". If it's destined to some other port (or even some other type of 'traffic') - I am pretty sure that many people would notice that. Just take a look at what kinds of questions (related to 'strange traffic') are posted on Firewalls/FW-Wizards/Incidents lists. Someone would ask about traffic to mirabilis.com, for sure... :) Of course, there is always a possibility that some disgruntled employee inserted a piece of code in order to get his/her "revenge" (for whatever reason).
