win496.com, tag58.com, rundll841.com and sslput4.com: another SQL injection attack

Yet another SQL injection attack doing the rounds, this time inserting references to www.win496.com/b.js, www.tag58.com/b.js and www.rundll841.com/b.js. The javascript redirects to sslput4.com/cgi-bin/index.cgi?ad. (Obviously, don't visit these sites unless you know what you are doing!)

All the domains run on a distributed botnet and were freshly registered this morning to a no-doubt fake address:

whois -h whois.crsnic.net win496.com ...
Redirecting to DIRECTI INTERNET SOLUTIONS PVT. LTD. D/B/A PUBLICDOMAINREGISTRY.COM

There are probably several different payloads, one we have seen is the Danmec trojan which drops a file called aspimgr.exe into the SYSTEM32 folder (more details here, here and here). The payload delivery may be randomised, it seems to be quite difficult to determine exactly what is going on.

If your server has been infected, then you need to do more than just clean it up.. you need to sanitize your SQL inputs. You can read more details of how SQL injections works here.

Right now it is difficult to say how many sites are impacted as the domains are really very new.

Added: you can add sysid72.com/b.js to this list too. That was registered 5 days ago, and a Google search already shows over 2000 hits. Also locale48.com has infected over 4000 pages in the same time frame.

Add 'sslnet72.com' to the list of these domains. I must have an old, unprotected form hanging out somewhere. Thought I'd nailed them all down, but no. Ironically, I'm in the middle of redesigning the site that I believe the hole is in, partly to ensure my forms are all capturing for illegal characters :(

I should be able to pick it up from my server logs, but still. And to answer the question, "who is responsible?" The designer. The fact that I have egg on my face for saying so at the moment doesn't change that.
