I have been getting this message very frequently in the last few days. I have not seen it before and it is originating from multiple different IP addresses. I do not believe that it is likely to be an actual hack attempts, but I would like to know the following:
1) what causes this response?
2) what would a "real" hack attempt reported in this way, likely look like?
3) Are customers seeing? (the hack attempts only seem to be related to my Photocart which is accessed via my blog)
4) How can I confirm that it is NOT a hack attempt?
Thanks for your help
