I have some unfortunate news to report. While monitoring my credit card statement, I discovered a more than $400US charge from a Chinese web site, obviously fraudulent.
I had not provided my credit card information to either uuorder.com or OfferAny.com. I asked for and received a PayPal invoice from uuorder.com and paid it. This is the company with the higher shipping fees.
OfferAny wanted either a credit card or cash via Western Union. During the elaborate sign-up process with Western Union, I was required to enter my credit card information, so I'm wondering if the hackers got my info from them. My credit card company refused the charge from Western Union--maybe they know something about the vendor or WU that we don't. When the charge didn't go through, I emailed OfferAny a request for a PayPal invoice, but never heard anything more from them. It's obviously impossible to determine exactly who got my card info, but when it happens on the same day that you're trying to do business with two Chinese sites, you have to be a bit suspicious. I've already canceled my credit card, and will have to provide the new account number to several legitimate businesses that have the old one on file. At least I'll have my new card tomorrow or the day after.
