Five senior Vodafone technicians have been accused of being the operational masterminds of an elaborate eavesdropping scandal enveloping the mobile phone giant's Greek subsidiary. The employees, named in a report released last week by Greece's independent telecoms watchdog, ADAE, allegedly installed spy software into Vodafone's central systems. The hi-tech rogue devices enabled 'persons unknown' to eavesdrop on conversations of the political, military and economic elite for nearly a year, the watchdog said. While some 106 mobile phones were monitored...the wiretaps were capable of intercepting around 4,000 local Vodafone subscribers, ADAE said...The report...also implicated a female technician employed by the company's infrastructure provider, Ericsson...Vodafone declined to comment.
