Something evil on 162.211.231.16

The server at 162.211.231.16 (IT7 Networks, Canada) is currently being used in injection attacks (example) which have been going on for some time [1] [2] and uses several domains, some of which are listed below.

The WHOIS details for these domains seem to be consistent but are possibly fake:

Registrant ID:CR148448937
Registrant Name:Leonardo Salim Chahda
Registrant Street1:Patron 6755
Registrant Street2:
Registrant Street3:
Registrant City:Capital Federal
Registrant State/Province:Buenos Aires
Registrant Postal Code:1408
Registrant Country:AR
Registrant Phone:+46.444407
Registrant Phone Ext.:
Registrant FAX:
Registrant FAX Ext.:
Registrant Email:info@brigitteunderwear.com

All the domains are very recently registered by GoDaddy. The WHOIS details for brigitteunderwear.com (also registered by GoDaddy in 2006) are consistent, but I've seen enough hijacked GoDaddy domains recently to be suspicious that there could be an element of identity theft here, and the named person may well have nothing to do with this attack.

I haven't had time to poke around at the payload too much, but this could well be a good IP to block, or alternatively use the list of domains that I have identified below (it may not be comprehensive, though)
