The CitizenLab published their report of the Blackshades RAT used by Syrian Electronic Army against activists. No need repeat their excellent analysis but you wish to analyze Blackshades and other RAT that were used in the Syrian attacks, here are the samples for 

• Blackshades RAT - June 2012 Citizen Lab Syrian Activists Targeted with BlackShades Spy Software
• XTreme RAT - May 2012  F-Secure Targeted Attacks in Syria
•  Dark Comet RAT - April 2012 - TrendLabs by Nart Villenueve
  

Looks like they are changing their RAT monthly.
