The ibe-redux seems legit, the epistane.com looks like a scam. THis is what I would do:
First thing tomorrow morning, call your credit card company and look at your most recent transactions, try and see if there are any unauthorized payments made etc..
If you are really paranoid, I would cancel the credit card. Get a new =one issued to you and pick it up at your bank.
Then call any businesses that have a pre-auth on your card i.e. cell phone company etc... and give them the updated information..
