This is the same malware as here http://www.sophos.com/blogs/sophoslabs/?p=9941

Would someone pls clarify:

ww-dot-robint-dot-us -OR- www-dot-robint-dot-us

// BLOCK which? or both?

Never mind...

"... Robint.us has been disabled, thanks to a sinkholing effort carried out by volunteer security outfit Shadowserver Foundation. The action will allow Shadowserver researchers to get a complete list of compromised sites and to gather additional information about how the attack was carried out.."

Shadowserver Sinkholing domain associated with SQLi attacks on IIS/ASP web servers

Please keep in mind that the IIS/ASP server is still vulnerable to the same type of attack. It's not a problem with IIS or ASP, but with the actual code "in" the ASP page.

In the below example from http://blog.sucuri.net/2010/06/mass-infection-of-iisasp-sites-robint-us.html, the field "utm_content" on the page "page.aspx" is the one that allowed the SQL injection to take place (output of IIS log truncated for readability):
2010-06-07 13:31:15 W3SVC1 webserver 192.168.1.10 GET /page.aspx utm_source=campaign&utm_medium=banner&utm_campaign=campaignid&utm_content=100×200′;dEcLaRe%

Block Both one redirects to the other.

Adobe 0-day used - mass injections

11 Jun 2010 05:38 PM - "... we started seeing mass injections... The attack is closely related to the hxxp ://ww.robint .us/[REMOVED].js attack earlier this week... common theme was that all Web sites were running on Microsoft IIS and used ASP.NET. In fact, the majority of sites compromised by the -new- mass injection attack still have the robint.us code present... Adobe released a patch* for this vulnerability yesterday and we advise all users to download it immediately... Once for IE and a second time for all other browsers."
