There are known sites for credit card number "hijacking" - whether this is one or not, I cannot say.
However, if ever (should be in caps "EVER") you have a question about a site that you have used your credit card # on, then immediately cancel that card and number. Better safe than sorry, there are ways that once they have the number, that multiple other pieces of private data attached to the card can be accessed by "naughty" people.
At that point canceling the card # becomes moot - they are already signing you up for lots and lots of additional credit that you never knew you had, and in hindsight wish that you did not, and now have to clear off your name.
Identity theft is a huge issue, here in the states and offshore. Where ever possible use a 3rd party pay procedure - such as PayPal (watch for phishing on PalPal, been known to happen). There are other 3rd party pass through pay sites, but this is the best known, well secured, and really quite a bit safer in the long run than directly using your credit card # for the transaction.
Granted not every site takes PalPal and their relatives, but check for the VeriSign and other secure "tags" that the site advertises, they generally will link to the security vendor site.
Yes there have been aberrations of the security tagging in some "hijacking" sites, but then again.....nothing is really fool proof, just be aware and cautious in all on line transactions. Better skeptical and not hitting the send button, than spending years trying to clean up the mess.
