“No alien quantum modems”: 1 to 3 concealed devices in Kyiv may be why Russian drones keep hitting so precisely, Ukraine’s top tech adviser says

Presidential adviser Serhii Beskrestnov, known as Flash, claims that one to three hidden transmitters may be operating in Kyiv, providing Russian drones with a brief online channel to strike precise targets. The devices, called MESH repeaters, are compact modems that relay a short control signal to a Geran at the moment of an attack.

Ukraine has been testing electronic warfare against these devices for months, but sealing the city with jammers alone will not be effective. Flash warns that as long as these repeaters operate, it will be difficult to shield Kyiv from Russian drone attacks. He believes there may only be 1 to 3 of these devices, but they are hard to find.

Flash points to the guided strike on Ukraine's Security Service headquarters as evidence, suggesting a MESH relay was switched on within five kilometers of the target for the duration of the attack. No other hidden links, such as LTE or Rassvet, were discovered. He emphasizes that jamming alone will not protect Kyiv, as the online control of drones remains a threat to bridges and air-defense assets.

As long as a stable channel exists up to the impact point, a drone cannot strike a bridge pier or cable precisely. Flash expresses uncertainty about his assessment of the repeaters but asserts that he has never been wrong in his technical reads of the enemy in the entire war.
