As announced some weeks ago the Skype trojan sourcecode will be available for download. You find the source packages in the Tools & sources section if you are the impatient type.
The code is simple and straightforward. You have know malware development is no rocket science and if you expect big magic you are at the wrong place. The backdoor receives instructions from the dropzone and transferres audio files. The Skype-Tap intercepts the Skype function calls, extracts and dumps audio data to files, converts it to the mp3 format and encrypts it.
The code is not 100% complete. I removed the plugin system in the backdor and also the firewall bypassing system is not there anymore. I will publish both of them in separate tools later. If you don’t like this … well, I can’t help you. Thats how it is. Take it or leave it.As always I am open for your opinions and criticism.
