Drones belligened the Phones of the Armed Forces: What are the dangerous complexes "Leer-3" for Ukrainians (video)

The invaders with the help of UAV fix the accumulation of phones in the territory of Ukraine, and then open fire from artillery. In order not to give out the location, the military should be very careful. The Russian military showed the work of the "Leer-3" complex, which is shocked by the mobile phones of the Ukrainian military. A pseudonym radiology expert, Sergei Flesh, told Facebook how you can deal with them.

As Sergei Flesh wrote, the KamAZ truck and 2-3 reconnaissance drones "Orlan-10" are included in the complex "Leer-3". The cars have operators, power supply and antenna transmitter. Drones can suppress mobile communications, but does it ineffectively because of low power, but well determine the location of the Armed Forces fighters by phone. On board "Orlan" installed a false base station of communication, which by its signal interrupts the tower of the operator.

The mobile phone is registered in a fake network because of the vulnerability in the GSM 900 or GSM1800 security protocol. The subscriber sees the network, but cannot call anywhere until the drone is flying out of the reach. At this time, the Russians see the SIM card number (not to be confused with the number in the operator network), IMEI serial number and location up to 500-100 meters, and can send SMS.

In the video from the RFI Ministry of Defense, shot in the Luhansk region, the invaders said they could detect phones on GSM, 3G and 4G. Operators transmit artillery of the Armed Forces of the Russian Federation on the location of three or more devices in one place, after which the Russians can fire on the coordinates obtained. "The operator says that the work of our HPs, which suppresses navigation, interferes with the work" Leer-3 ". We take note.

But here I do not exclude deliberate misinformation," Leer-3 "is able to navigate, except GPS, at the signals of Ukrainian base stations mobile communication. ", - said Sergei Flesh. The expert also noted that Orlan needs to fly a certain territory for accurate signals. In addition, the Russians mentioned the modules of "purpleding" (signal replacement), which had not been known before. Information about the flight time of up to 10 hours and the ability to work in the rear was confirmed.

"I am glad to my military colleagues: Front is not a couple of kilometers advanced. Don't carry the phones on where it gets the art. LTE with a wi fi distribution in the dugout (below the ground). This is visible Rer as one phone, "Sergei Flesh wrote. As early as March 2022, the Minister of Defense of Ukraine Alexei Reznikov called on the destruction of the complexes of the EW "Leer". He explained that without them the Russians will be vulnerable to the blows of the Ukrainian army.
