[See the update below]
On Friday we reported that the Dolphins Stadium (home of the 2007 Super Bowl) was infected with a scripted pointer to malware that exploited two patchable Microsoft Windows vulnerabilities. While doing research on that issue we uncovered many more sites that contain similar references. Here is a list of the some of the ones we found, many have already been cleaned up but many have not. System administrators might want to check their network flow logs for any traffic to these sites, and for any traffic to the five sites that hosted the hostile Java script.
It looks like the "1.js" intrusions happened around the first of January while the "3.js" intrusions occured near the end of January. We cannot find any evidence of a "2.js" or "4.js" script. In the references below, I changed the word "script" to "skript" in order to prevent any accidental mis-fires.
A common theme seems to be an attack on hospital or medical care sites, although that is not completely the case. We checked to see if this was a mass attack on one service provider but other than a lot of *.squizzle.com sites it does not appear to be this type of attack.

A reader sent us this:
I think the 1.js problem goes back a bit further in time. I found these logs:
Fri Dec 1 10:08:44 2006: x.x.x.x -> 18.104.22.168: 54995 -> 80 GET /1.js HTTP/1.0 (bc0.cn)
Wed Dec 6 11:42:05 2006: x.x.x.x -> 22.214.171.124: 55089 -> 80 GET /1.js HTTP/1.0 (bc0.cn)
Mon Dec 11 14:17:04 2006: x.x.x.x -> 126.96.36.199: 51732 -> 80 GET /1.js HTTP/1.0 (bc0.cn)

...which makes us curious as to when this incident started. If you could check your logs and let us know about detections prior to December 1st 2006 we would greatly appreciate it. We'll post an update here later today or tonight.
