MEHUL SRIVASTAVA, MADHUMITA MURGIA, AND HANNAH MURPHY, FT (3/9/2022, 8:33 AM) The secret US mission to bolster Ukraine’s cyber defences ahead of Russia’s invasion European official: "instead of communicating solely through encrypted military-grade phones, Russian commanders are sometimes piggybacking on Ukrainian cell phone networks to communicate, at times simply by using their Russian cell phones.
'The Ukrainians love it—there is so much data in simply watching these phones, whether or not they are using encrypted apps,' he said.
The Ukrainians then block Russian phones from their local networks at key moments, further jamming their communications. 'Then you suddenly see Russian soldiers grabbing cell phones off Ukrainians on the street, raiding repair shops for sims,' he said. 'This is not sophisticated stuff. It’s quite puzzling."
