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.
