We've developed a Wireshark plugin that will allow you to view obfuscated pcaps of traffic from a Mariposa infected client and actually decrypt them within Wireshark. The software is available to all as open source software under the GNU GPL license. We hope that it helps in doing further investigation and research into the Mariposa botnet.
Special thanks to Defence Intelligence for their analysis on Mariposa.
