MiniPanzer

MiniPanzer is a Swiss government surveillance trojan (a Bundestrojaner, or “federal Trojan horse”) and a variant alongside MegaPanzer. It was written in C++ by Ruben Unteregger for ERA IT Solutions, a contractor to the Swiss federal government. Reporting in the provided content states that Switzerland’s Federal Department of Environment, Transport, Energy and Communications (UVEK) later used MiniPanzer to intercept Skype and other voice-over-IP traffic on Windows XP systems. The malware runs on Windows x86 and has been described as using DLL injection. The source code was released under GPLv3 by Unteregger, with copyright retained, and was hosted on SourceForge; after that release, the trojan was reportedly detected in the wild. Anti-virus vendors identified at least one designation for the malware as Trojan.Peskyspy. The content does not provide specific hashes, domains, or other concrete IOC values beyond that AV naming and the DLL injection behavior.
