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:


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


Which then redirects to ad.js which redirects the user to

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

AV coverage is decent:

UPDATE (thanks again Elazar!)

This post has a nice running list of domains:

The cause seems to be the ASPROX bot kit, which got some SQL injection capabilities in mid-May, see

Dr. Ulrich's post lays out very nicely how it all happens...

The folks at ShadowServer are keeping a comprehensive and updated list at:
