If you have an interest in computer security (we all should), this article at The Citizen Lab, does a very good job explaining how middle eastern countries target and spy on dissents. It is the best technical review I have seen of a state sanctioned malware attack .
The final advice the Citizen Lab gives is below, it is very good advice. I recommend this article to any one who is interested in the technical side of this issue.
The use of social engineering and commercial surveillance software attacks against activists and dissidents is becoming more commonplace.
For at risk communities, gaining awareness of targeted threats and exercising good security practices when using email, Skype, or any other communication mechanism are essential. Users should be vigilant concerning all e-mails, attached web links, and files. In particular, carefully assess the authenticity of any such materials referencing sensitive subject matter, activities, or containing misspellings or unusual diction. If you believe that you are being targeted be especially cautious when downloading files over the Internet, even from links that are purportedly sent by friends.
