Duqu - RAT Trojan, "Precursor to the Next Stuxnet" - samples


Img: materkat.wordpress.com
Oct 20 = Note: I added another file. 

According to Symantec:
"Duqu does not contain any code related to industrial control systems and is primarily a remote access Trojan (RAT). The threat does not self-replicate. Our telemetry shows the threat was highly targeted toward a limited number of organizations for their specific assets. However, it’s possible that other attacks are being conducted against other organizations in a similar manner with currently undetected variants.
The attackers used Duqu to install another infostealer that could record keystrokes and gain other system information. "

Rustock samples and analysis links. Rustock.C, E, I, J and other variants

 

 I thought that Russian Matryoshka aka Rustock the Nested Doll would be a good subject after the previous post about Trojan.Matryoshka (Taidoor) analyzed by Jared Myers from CyberESI. Russian rootkit Rustock is as notorious as TDSS or Stuxnet and is very sophisticated. Many researchers made detailed analysis of Rustock and this is why it is a great subject of study. The botnet is down but the malware is here for you to play and try to reverse on your own or following one of the analysis papers posted below.

Sep 28 CVE-2010-3333 Manuscript with Taidoor (Trojan.Matryoshka by CyberESI)



CyberESI
Jared Myers from CyberESI posted a fantastic detailed analysis of Taidoor trojan variant he called Trojan. Matryoshka for being just a container/carrier for another malicious file "Trojan.Einstein". See Trojan.Matryoshka and Trojan.Einstein   The trojan arrived in a malicious RTF attachment CVE-2010-3333 from a a spoofed address of the National Chengchi University / NCCU of Taiwan. The actual sending host was a server  IBM111, which is used by a particular group of attackers and is seen quite frequently. This sample was donated by a reader but I have a lot of IBM111-produced attachments if you are after them.
