The worm’s author periodically modifies <br /> the source code to avoid detection. Some variants are compiled to native <br /> code, while others are compiled to Pseudo-code. For this paper, a native <br /> code version of W32.Changeup was selected and decompiled in order to <br /> understand how the worm had been created and how the worm behaves. <br /> This paper presents the partial source code of the worm, as well as the <br /> method used to decompile a Visual Basic native code program by hand.<br /> |Keyword=Worm, Visual Basic<br /> }}<br /> Blog entry: http://www.symantec.com/connect/blogs/w32changeup-how-worm-was-created</div>
