Minutes after the end of the ceasefire in Ukraine, that country's air force and the Ukrainian government's disinformation center announced that the country's airstrike warning system may have been hacked, as several fake warnings about the threat of radioactive materials appeared in this application.
The Ukrainian Air Force announced in a message: "The application to warn of an air attack is probably a target for a ground attack and hostile sabotage." "There is no radiation threat."
The spokesperson of the Ukrainian Air Force also confirmed in a conversation with AFP that this application was hacked.
Ukraine's Center for Strategic Communications, in a statement on Channel X, blamed Russia for this ground-based cyber attack, but the Kremlin did not respond to this accusation.
Kyiv city authorities also announced that another app designed specifically for the Ukrainian capital is still working as usual.
Warning of radiation risk not necessarily a nuclear ground attack. Such a warning can also be related to the possibility of a leak of radioactive materials from a nuclear facility or the release of radioactive materials.
