We're getting traffic directed from strange referring sites. I have noticed this in the past and not sure why it happens, but I am guessing it's related to some sort of hack or attack on our sites and possibly from hacked servers.
Here are some examples with the IP that made the request and the referrer - these three requests came one after another so would kind of assume they are related in some way:
