Almost identical in every way to this injection attack, several Dreamhost sites have been compromised with a page called yahlink.php (it was yahoolink.php before), which is being spammed out through compromised AOL accounts.
It isn’t just Dreamhost hosted sites that are being spammed out in this way, but it does appear that well over half the sites are on Dreamhost. It looks like some GoDaddy customers might have been hit too.
In this case, the spammed link directs to krokodilius8.com/gosem11.php which is hosted on 78.129.132.26 which appears to be iomart Hosting Ltd in the UK. All the sites on that server appear to have have fake registrant details, so you can assume that they are bogus:
bepfinance.com
brentnallfg.com
estatediary.com
forfreeblog.net
freeblogpro.org
freetrialmail.com
krokodilius8.com
lucky-bet.in
pubertavad.com
russwoman.ru
superblogonline.org
thebloggin.net
vedrozhuk7.com
yourtraveldiary.net
Users are then directed to another host in Romania, 188.229.89.230 which belongs to Netserv Consult SRL. It is my opinion that there is nothing of value in the entire 188.229.0.0/17 range and you can safely block access to the entire lot.
The final step is to a host called drugstorehealthrisks.net hosted on 90.182.175.232 which looks like a broadband connection in the Czech Republic. The site isn’t loading for me, but I guess it’s just pharma spam. These other sites are hosted on the same server:
fatdrugstoremeds.net
healthrxinsurance.net
healthrxpharmacyinsurance.com
healthtabletsnook.net
Dreamhost have been informed of the issue but don’t appear to have done anything to secure their users. Blocking Dreamhost IPs might be something worth considering depending on what kind of shop you run. I have spotted malicious activity in the following IP ranges:
67.205.0.0/18
69.163.128.0/17
75.119.192.0/19
208.97.128.0/18
..although blocking access to the Romanian 188.229.0.0/17 block would also pretty much acheive the same thing without blocking access to any legitimate sites that might be on Dreamhost.
