Members of a spy ring plotted in autumn of 2022 to capture identifying details from mobile phones at a US airbase in Stuttgart in the belief that Ukrainian soldiers were training there on how to use Patriot air defence systems, the Old Bailey heard.
They planned to use a sophisticated device known as an Imsi catcher to obtain the unique number of each phone and its sim card and pass on information that could be of benefit to Russia in its invasion of Ukraine, prosecutors said.
