More SQL Injection with Fast Flux hosting

One of our readers, Elazar, send us some very good analysis of a SQL injection attack.  A summary of his findings are below.  We really appreciate it when readers observe an event, apply some noodle, then send in the analysis.  Thanks Elazar!

Looks like another hit, within the last week or so. More fast flux domains redirecting to other domains which then redirect to the malware site. What's interesting about this one is it doesn't look like they are using exploits to install the malware, they are redirecting to a fake AV site which fools users into installing the malware. Some of the domains hosting the injected js are as follows:

hxxp://updaead.com
hxxp://upgradead.com
hxxp://clsiduser.com
hxxp://dbdomaine.com

b.js then redirects to several domains which host a cgi script

hxxp://kadport.com/cgi-bin/index.cgi?ad
hxxp://hdadwcd.com/cgi-bin/index.cgi?ad

Which then redirects to ad.js which redirects the user to
hxxp://spyware-quick-scan.com?wmid=1041&l=14&it=1&s=4t

This site attempts to trick the user into installing installer.exe

AV coverage is decent:
