Greetings good friends. Terribly sorry for the late share and post.
Sample of this post: http://malwaremustdie.blogspot.jp/2013/ ... -dead.html
Is attached with the password, I changed all pwd into this one.
Just done last checks, ZA is not even close to reduce in peers quantity, infection vectors, nor domains in distributions..
Symantec should allocate their budget more to real ZA research than promotion of electricity energy. Hence, no hash.
But it has interesting vector that we can use to shut this down, we are start working on it. Pls support!
Be free to join in next botnet OP.

zs.exe and SpringSvc.exe has nothing to do with ZeroAccess itself. Seems they are 3rd party components here. Both written in CodeGear RAD studio in Delphi language and zs.exe is primitive downloader packed with AsPack, SpringSvc.exe is using TWebBrowser component. All *.tmp files are copies of SpringSvc (must be temporary files created by zs.exe downloader).

unpacked results for both
