On March 7, 2005, Ericsson notified Vodafone of the existence of rogue wiretaps and software in their systems. The next day the general manager of the Greek Vodafone branch, George Koronias, asked for the software to be removed and deactivated. Because the rogue software was removed before law enforcement had an opportunity to investigate, the perpetrators were likely alerted that their software had been found and had ample opportunity to turn off the "shadow" phones to avoid detection. According to the head of Greece's intelligence service, Ioannis Korantis: "From the moment that the software was shut down, the string broke that could have lead us to who was behind this."
