As reported by the Russian Ministry of Defense, the Russian-made RB-341V “Leer-3” electronic warfare systems use three Orlan-10 unmanned aerial vehicles (UAVs) connected to a KamAZ-5350 truck that serves as the command and control post to affect a six-kilometer (3.7-mile) radius. The UAVs jam nearby cellular communication towers through a combination of jammers installed on the UAVs and disposable jammers that are dropped on the ground. The UAVs are then able to send SMS text messages and audio messages, effectively hijacking nearby cellular transmissions. Though originally designed to function with GSM networks, the Leer-3 is known to more recently be used with 3G and 4G networks.
These specific electronic warfare systems are officially known to be used by Russia in Syria. The OSCE Special Monitoring Mission (SMM) to Ukraine observed an Orlan-10 on May 13, 2017, flying from separatist-controlled Makiivka to Donetsk city. In a statement at the OSCE 822nd FSC Plenary Meeting, the Ukrainian delegation presented evidence of the “Leer-3” electronic warfare system in Donetsk city.

Je vois bien comment brouiller les BTS légitimes pour y substituer un BTS pirate en MITM - le GSM n’authentifie rien... Mais en 4G le réseau est censé être authentifié par le terminal (cf. ▻https://www.troopers.de/wp-content/uploads/2011/10/TR12_TelcoSecDay_Schneider_LTE.pdf) et s’introduire là-dedans est une autre paire de manches... Il me semble que pour y arriver il faut avoir compromis certains éléments de l’infrastructure. S’ils y parviennent, c’est fort.
D’après ▻https://twitter.com/GuyPlopsky/status/868352180612284416 l’upgrade de Leer-3 pour traiter 3G et 4G a été annoncé mais personne n’a encore témoigné de son efficacité opérationnelle.
