Hacker Question

Hi, I have a guy who buy items on my cs-cart multi vendor site and when he gets transfer to paypal for payments he changes the amounts to 1 cent. Fortunately the transaction fail as "The paid total amount does not match the order total "

But I would like to know who this users is doing this? Anybody knows?



There is a Firefox extension called Tamper Data that will let people change the data passed to Paypal. Good thing is that cs-cart check if the payment amount and order amount is the same.

Do you know if there is a way to encrypt data going to Paypal? If I had a SSL certificate, would it encrypt it?

Thanks all,
