Suspect ad network leads to PDF exploit

This was picked up from an ad apparently running on grooveshark.com

An ad from ad.technoratimedia.com loads an ad from ad.yieldmanager.com.. so far, pretty normal.

The next step is:
ads.bootcampmedia.com/servlet/ajrotator/790744/0/vh?ajecscp=1254835789307&z=BootCamp&dim=335848

This domain is protected by DomainsByProxy, registered in December 2007 and is hosted 208.113.133.105.

The site has the following contact details:
Address

Bootcamp Media

Suite 202
Guelph, Ontario, Canada
N1H 4E9
Phone

Bootcampmedia.com has a near-zero profile, but it may well be a legitimate company.

After this, the visitor starts to go well off the beaten track. The next hop is traffic.firedogred.com/content?campaign=1219131&sz=2

That email address of trafficbuyer@gmail.com is well known. The subdomain traffic.firedogred.com is dual-homed on 207.57.97.233 and 161.58.56.25 (both NTT America, Inc).

The next hop is show.sheathssubtotal.info/rotate?m=3;b=2;c=0;z=406377

sheathssubtotal.info was regisitered on 17th September with the same "trafficbuyer@gmail.com" contact details as firedogred.com.

show.sheathssubtotal.info is dual homed on 140.174.93.100, 161.58.192.228 (both NTT America, Inc).

Yet another hop, this time to content.neighbanner882.info/track/3388081/S_SE?{munged}

neighbanner882.info was created on 7th August 2009, registered to trafficbuyer@gmail.com (again). content.neighbanner882.info is hosted on 69.164.196.55 at some outfit called Linode.

Yet another hop, this time to winckag.com which is currently down but was hosted on 89.149.251.71 (Netdirekt E.k) who are pretty well known for hosting bad sites (but they may well have nuked this one already, and if so.. well done!)

The owners of winckag.com have something to hide..

This loads an image from img.sheathssubtotal.info/120x600/54019.gif multihomed on 174.143.241.174, 174.143.243.90, 174.143.243.162 (some sort of cloud hosting) and then loads the following:
winckag.com/base/data/p29.php
winckag.com/base/data/vou.png

Those nameservers on 200.63.45.62 are interesting, that's PanamaServer.com who are well known for supporting malware.

Finally, winckag.com appears to try to load a Troj/PDFJs-DY trojan onto the victim's machine.

You should certainly avoid ads running on firedogred.com, sheathssubtotal.info, neighbanner882.info, winckag.com or any domain registered to trafficbuyer@gmail.com. Make up your own mind about Boot Camp Media - these small ad networks are very often targeted by the bad guys, but they really need to get their act together.
