Bundestrojaner
Almost 5 years ago, I speculated that a state trojan launched by the German government and the BKA would soon be detected by common anti-virus scanners ("Eine hohe Verbreitung vorausgesetzt, werden nach einer gewissen Anlaufzeit vermutlich auch alle Malwarescanner in der Lage sein, den Bundestrojaner zu erkennen.")
The following screenshot illustrates the situation just one day after the CCC disassembled code they believe to represent such a state trojan.
