Nuclear radiation in Russia, Ukraine? No, just hack alerts! Warnings are scaring people in Ukraine, but authorities say they cleared up the confusion in less than an hour. Ukraine and Russia have accused each other of hacking systems used to send emergency alerts to citizens, raising fears of a new escalation of digital and psychological warfare tactics. The systems apps sent out two radiation alerts to citizens on Sunday before officials issued public clarifications. The fake threats began on the same day that the local ceasefire in Russia's Kherson region came to an end on Sunday. Al Jazeera.
