MegaPanzer

MegaPanzer is a Swiss government surveillance trojan and a variant of the Bundestrojaner (“federal trojan”) family, alongside MiniPanzer. It was written by Ruben Unteregger for ERA IT Solutions, a contractor to the Swiss federal government, and its source code was hosted on SourceForge. Reporting in the provided content states that Switzerland's Federal Department of Environment, Transport, Energy and Communications (UVEK) later used MiniPanzer and MegaPanzer to intercept Skype and other voice-over-IP traffic on Windows XP systems. The malware runs on Windows, with the related source described as C++ for x86, and the content states that the malware used DLL injection. After the source code was released under GPLv3 while copyright was retained by the author, the trojan was reportedly detected in the wild. Anti-virus vendors are said to have identified the malware as Trojan.Peskyspy. The content characterizes MegaPanzer as an example of “govware” or state surveillance malware used for lawful-intercept style monitoring.
