I'm sorry to say, I've had absolutely no response from the site owner, or hosting company for the site I mentioned previously that was hacked (obiettivorisarcimento.it). The injected code is still present, as can be seen by the following vURL query;
Even worse however, is that it doesn't appear this is limited to just the one site. Checking other sites on the same IP block, shows the same injected code, for example;
The following is a list of sites on the same IP block (18.104.22.168).
It's worth noting that not all of the above hosts are showing the injected code as being present. Whether this indicates a network wide issue, or the affected sites are just on the same server, is anyone's guess.
Until this is cleaned up however, I'd strongly recommend blacklisting this IP block.
In the meantime, if anyone reading this, happens to live in Italy and would like to try and get hold of the hosting company, their details are as follows;
Thus far, attempts to contact them both via e-mail and via telephone, have failed miserably.

I'd like to make clear, following a note on the forums, that it is only the single IP (22.214.171.124) I recommend blocking, and not HostingSolutions.it entire net-range.
