These are the high profile sites targeted by the same group within the past 48 hours, with number of locally cached and IFRAME injected pages within their search engines :

NCSU Libraries - lib.ncsu.edu - 372,000 pages
FullDownloads.us - fulldownloads.us - 13,000 pages
Central Statistics Office Ireland - cso.ie - 10,300 pages
DBLife Frontpage - dblife.cs.wisc.edu - 1,130 pages
School of Mathematics and Statistics - www-history.mcs.st-andrews.ac.uk - 1040 pages
eHawaii Portal - ehawaii.gov - 992 pages
The World Clock - timeanddate.com - 944 pages
Boise State University - boisestate.edu - 471 pages
The U.S. Administration on Aging (AoA) - aoa.gov - 425 pages
Gustavus Adolphus College - gustavus.edu - 312 pages
Internet Archive - archive.org - 261 pages
Stanford Business School Alumni Association - gsbapps.stanford.edu - 157 pages
BushTorrent - bushtorrent.com - 147 pages
ChildCareExchange - ccie.com - 131 pages
The University of Vermont - uvm.edu - 120 pages
Hippodrome State Theatre - Gainesville, FL - thehipp.org - 112 pages
Minnesota State University Mankato - mnsu.edu - 94 pages
The California Majority Report - camajorityreport.com - 16 pages
Medicare.gov - medicare.gov - 12 pages
USAMRIID - usamriid.army.mil - 3 pages

This sample of the newly introduced .info domains reside on the same netblock as the previous ones - 75.125.181.0/255 a KISS strategy making it easier to respond to this incident. Best of all, they further expand the campaign since they're injected in plain text, next to javascript obfuscated, this time embedded malware :

hickey.info
kbst.info
sezejc.info
mloqrd.info
mqghrd.info
ymrxwd.info
fsqpsm.info
haxkwd.info
aagpcw.info
zdksgj.info
cgjttz.info
hkedny.info
kbsxet.info
wapdjw.info
kbsxet.info
tdwham.info
mqghrd.info
dhqjdz.info
bhrsaa.info
jramae.info
wmtwes.info
tacpmh.info
qwhhxq.info
gmjett.info
hkedny.info
rerkqz.info
bhrsaa.info
txmwxb.info
psyckr.info
jramae.info
nhwdrh.info
cqqxkh.info
stysqf.info
tgzyqz.info
kbsxet.info
cgjttz.info
tazbhk.info
kbsxet.info

Each of the these is loading a secondary domain, which is then taking us to two more before finally reaching the Zlob variant. In this case it's radt.info (75.125.208.243) with several campaigns currently up and running, pointing to the same fake codec. And the samples redirects upon visiting these as follows :

seivomerutam.info/Free-Paris-Hilton-Nude-Pics/
seivomerutam.info/spam/

all of which ultimately redirect to :

porn-popular.com (64.28.185.78) where the Zlob variant in the face of a fake codec, is downloaded from democodec.com/download/ democodec1292.exe (64.28.184.168) via an Active X object.

Scanner results : 22% Scanner(8/36) found malware!
File Name : democodec1292.exe
File Size : 74823 byte
MD5 : 30965fdbd893990dd24abda2285d9edc
SHA1 : 53eacbb9cdf42394bd455d9bd2275f05730332f7
Downloader.Zlob.ZV; Trojan-Downloader.Win32.Zlob.eie; TrojanDownloader.Zlob.epx

It gets even more interesting as according to Computer Associates :

"This fake codec is actually a hijacker that will change your DNS settings whether you are aquire your IP settings through DHCP or set your IP information manually. This hijacker will attempt to re-route all your DNS queries through 85.255.x.29 or 85.255.x.121. If you use a static IP address, CA AntiSpyware will set your DNS server to 198.6.1.1 to prevent your DNS queries from continuing to go through the rogue DNS servers. Please change your DNS server to the DNS server provided by your IP or Network Administrator."

What this means is that known Russian Business Network netblocks are receiving all the re-routed DNS queries from infected hosts, thereby setting up the foundations for a large scale pharming attack by infecting the weakest link, the end user from the perspective of using rogue DNS servers, a much more effective but noisy approach.

To sum up - it's a mess that I'll continue trying to structure, and it's a single group exploiting input validation capability within the sites' search engines we're talking about. With this segmented targeting of sites with high page ranks, and their persistance, is already positioning hundreds of thousands of keywords within the top search results, with the targeted sites are acting as the redirectors to the malware locations.
