IRS/PhotoArchive Themed Zeus/Client-Side Exploits Serving Campaign in the Wild

SECOND UPDATE for Wednesday, February 24, 2010 - Another portfolio of new domains is being spamvertised, using the old PhotoArchive theme.

UPDATED: Wednesday, February 24, 2010 Another portfolio of typosquatted domains has been spamvertised. The already suspended domains are listed for historical OSINT analysis of this gang's activities.

Interestingly, their campaigns are lacking the quality assurance I'm used to see. For instance, the iFrame IP ( /usa50/in.php) is currently down, with the malware itself, including the one that would have been dropped given the exploitation took place - have over 90% detectio rate, since the binaries were first analyzed a month ago - tax-statement.exe - Trojan-Spy.Win32.Zbot - 40/42 (95.24%); abs.exe - Packed:W32/Mufanom.A - Result: 38/42 (90.48%). The directory structure also remains the same - irs.gov.yrxc.kr/fraud.applications /application/statement.php

UPDATED: Sunday, February 21, 2010 - The gang is currently spamming a phishing campaign -- no client-side serving iFrames found so far -- attempting to steal Google account and Blogspot accounting data. Given the fact that the gang is capable of generating hundreds of thousands of bogus accounts on their own, as well as buy them in bulk orders from vendors that have already built such an inventory across multiple social networking sites, the only logical reason for attempting to phish for such data would be to attempt to maliciously monetize the traffic of legitimate blogs.

As anticipated, the botnet masters behind the systematically rotated campaigns dissected in previous posts, kick off the week with multiple campaigns parked on the newly introduced fast-fluxed domains.
In a typical multitasking fashion, two campaigns are currently active on different sub domains introduced at the typosquatted fast-flux ones, impersonating the U.S IRS with "Unreported/Underreported Income (Fraud Application) theme", as well as a variation of the already profiled PhotoArchive campaign, using a well known "You don't have the latest version of Macromedia Flash Player" error message.
Let's dissect both campaigns, sharing the same fast-flux infrastructure, and currently spammed in the wild.

Sample campaign URLs from the PhotoArchive, SecretArchives themed campaign:
- archive .repok.or.kr/archive0714/?id=test@test.com
- secretarchives .renyn.kr/archive0714/?id=test@test.com
- secretfiles .repo1it.me.uk/archive0714/?id=test@test.com
- secretarchives .renyn.ne.kr/archive0714/?id=test@test.com
- postcards .repo1ix.co.uk/archive0714/?id=test@test.com 

Sample sub domain structure:
anonymousfiles .repo1i2.me.uk
archive .repo1iq.me.uk
archive .repo1it.me.uk
archives .repo1i1.me.uk
filearchive .repo1i1.me.uk
files .repo1it.me.uk
files .repo1ix.me.uk
files4friends .repo1it.me.uk
secretarchives .repo1iq.me.uk
secretarchives .repo1iw.me.uk
secretarchives .repo1ix.me.uk
secretfiles .repo1iq.me.uk
sendspace .repo1i2.me.uk

archive .repo1ix.co.uk
archives .repo1iq.co.uk
archives .repo1ix.co.uk
files .repo1iq.co.uk
files4friends .repo1ix.co.uk
incognito .repo1iq.co.uk
postcard .repo1iq.co.uk
postcard .repo1iw.co.uk
secretarchives .repo1iw.co.uk
www.irs.gov .repo1ix.co.uk

Embedded iFrame - /ukasp/in.php (AS42229 (MARIAM-AS PP Mariam) attempts to exploit CVE-2007-5659; CVE-2008-2992; CVE-2008-0015; CVE-2009-0927 and CVE-2009-4324. Upon successful exploitation, file.exe - Trojan-Spy.Win32.Zbot.gen - Result: 12/41 (29.27%) is served. Just like the original update.exe - Trojan.Zbot - Result: 13/40 (32.50%) available as a manual download from the pages, both samples phone back to the well known elnasa.ru /asd/elnasa.ble - - Email: kievsk@yandex.ru - Aleksey V Kijanskiy.

Naturally, AS42229 (MARIAM-AS PP Mariam) is a cybercrime-friendly AS, with the following currently active Zeus C&Cs parked there:

Sample URL from the IRS-themed campaign:
- irs.gov .renyn.kr/fraud.applications/application/statement.php

Sample iFrame from the IRS-themed campaign - /usa50/in.php is currently down. The same IP was used to serve client-side exploits in a previous campaign - "Pushdo Serving Crimeware, Client-Side Exploits and Russian Bride Scams".

Detection rate for tax-statement.exe - Trojan-Spy.Win32.Zbot.gen - Result: 37/41 (90.25%), which upon execution phones back to the well known nekovo.ru /cbd/ nekovo.br - - Email: kievsk@yandex.ru - Aleksey V Kijanskiy

Interestingly, researchers from M86 Security gained access to the web malware exploitation kit used in a previous campaign:

"It has been up and running and serving exploits for nearly a day. In this time almost 40,000 unique users have been exposed to these exploits, and the Zeus file has been downloaded over 5000 times. These downloads do not include the PhotoArchive.exe file downloads that a user may be tricked into downloading and executing themselves."
Updated will be posted as soon as new developments emerge.
