MiniPanzer and MegaPanzer
two variants of the malware Bundestrojaner

MiniPanzer and MegaPanzer are two variants of Bundestrojaner (German for federal Trojan horse) written for ERA IT Solutions (a Swiss federal government contractor) by software engineer Ruben Unteregger, and later used by Switzerland's Federal Department of Environment, Transport, Energy and Communications (UVEK) to intercept Skype and more generally voice over IP traffic on Windows XP systems.
The source code of the program was released under the GNU General Public License version 3 (GPLv3) in 2009 by their author, who retained the copyright. Thereafter, the trojan was apparently detected in the wild. One of its designations given by anti-virus companies was Trojan.Peskyspy.
The malware used DLL injection.
Begin with the source’s own compact description: “MiniPanzer and MegaPanzer” is two variants of the malware Bundestrojaner. The dossier treats that line as a proposition to test through MiniPanzer, MegaPanzer and variants, not as a finished interpretation.
Why this record matters
The phrase “two variants of the malware Bundestrojaner” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 13, 2026. The linked authority identifier is Q17101002. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2009.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
