Ok thanks.
I am in touch with Sagepay & Global payments. It's good to let others know that this can happen, it's the first time I've ever heard of it.

Hi,

You need to speak to the payment gateways you are using about this.
We connect to hosted payment pages in most cases so they should have an option to put a capcha on there if there is an unusual amount of traffic.
Either way - it needs to be implemented on there as even restricting on RomanCart may not prevent that activity on the actual hosted payment page of which we are not in control
Many Thanks
Support

March 11th/12th I had what I now know was a card attack with around 4950 attempts to process stolen card details. I didnít realise that I would be charged by Global Payments for the authorisation attempts, even though they failed but this has left me around £300 out of pocket.

I have now restricted the access to only accept calls from my URL & have blocked all countries other than the UK (better late than never) but am worried this could happen again. The payment attempts were every few seconds, so it can rack up the charges very quickly.

Is there anything else that can be done, particularly restricting the number of failed authorisations?
If I wasnít here to block IPís I assume it would have just kept going.

I use Sagepay, but there isnít anything there to restrict it?
