Something evil on 151.248.123.170, Part III

I've covered 151.248.123.170 (Reg.ru, Russia) a couple of times in the past month [1] [2], and it's still actively pushing out malware via dynamic DNS domains, many of which are injection attacks on hacked sites.

There are hundreds or possibly thousands of malicious domains on this IP. Blocking them individually is likely to be problematic, the best approach is to block all traffic to 151.248.123.170 or to the Dynamic DNS domains involved.. although this might potentially block access to some legitimate sites.

These are the Dynamic DNS domains being abused (you should consider blocking them in my opinion):
3utilities.com
4mydomain.com
4pu.com
changeip.org
ddns.ms
ddns.us
dns04.com
dsmtp.com
dynamicdns.biz
dynamic-dns.net
freeddns.com
ftpserver.biz
ikwb.com
itemdb.com
jetos.com
lflinkup.net
mefound.com
myddns.com
myftp.org
myfw.us
mypicture.info
mysecondarydns.com
myvnc.com
ninth.biz
no-ip.biz

ns01.biz

ns02.us
ns3.name
ocry.com
organiccrap.com
otzo.com
port25.biz
redirectme.net
servebeer.com
serveblog.net
servecounterstrike.com
serveftp.com
servegame.com
servehalflife.com
servehttp.com
servemp3.com
servepics.com
servequake.com
serveusers.com
xxuz.com
youdontcare.com

These are the domains that I can detect on the IP, but there are probably many, many more.
