The guys at http://www.rstack.org have done quite a bit of work on Skype (and more particularly Skype security), the Chinese DIDN'T "crack" the Skype protocol they were simply the first people to release an alternative client. Rstack.org's were the first to "crack" the protocol, the details can be found in Philippe Biondi's and Fabrice Desclaux's blackhat briefings eu 2006 presentation "Silver Needle in Skype"; http://www.blackhat.com/presentations/bh-europe-06/bh-eu-06-biondi/bh-eu-06 -biondi-up.pdf Further work was done later into Skype-based botnets, details are available in Cedric Blancher's "Fire in the Skype" presentation; http://sid.rstack.org/pres/0606_Recon_Skype_Botnet.pdf
Actully not to belittle team RStack (hi guys, and girls) and their work but the first analysis I saw of the Skype protocol was the 2004 paper from Salman A. Baset and Henning Shulzrinne at the CS dept. of Columbia University. This paper started a lot of other research. Just to give credit where credit is due. cheers, --dr -- World Security Pros.
