I recently discovered that my credit card had been used to buy $400 worth of Steelers/Colts tickets on ticketsnow.com. Luckily, I caught it in time to have Ticketsnow cancel the order. They are investigating fraud. This is strange because the tickets had to be ordered online or by phone because I still have the credit card and had it the day it was used. If the order was made online or by phone, the person would need my billing address. The only place both my credit card number and billing address are present is on my computer (or my wallet, but we can rule that out since I haven't lost it) - which makes me lean towards some sort of security breech on my computer. As I travel around throughout the day, my computer is frequently on unsecured networks, where I try to avoid doing financially sensitive things - but I would imagine its possible to gain access to personal information even if I'm not using it. Anyways, I was hoping to confirm this notion of a security breech so that I can determine exactly how much information was compromised. I've run a credit report, but even that wasn't up-to-date enough to see a new auto loan from a couple weeks ago - so I need to wait a bit for that to catch up to whatever is happening now. So is there something I can do to find out if I've been hacked?
