Lars Sobiraj writes "Ruben Unteregger has worked for a long time as a software-engineer for the Swiss company ERA IT Solutions. His job there was to code malware that would invade PCs of private users, and allow the wiretapping of VoIP calls — in particular, calls made through Skype. In the German-speaking areas of the country, the Trojans were called 'Bundestrojaner' because the Swiss government was involved with their development and use. Unfortunately, Unteregger has to remain silent about the customers of the company. Last night, he published the source code of his Skype-Trojan under the GPL."
