Ukrainian air alert app hacked with fake nuclear warnings | 2 Nov 2026 | Ukraine’s government-backed mobile air alert app sent out false warnings of nuclear and chemical attacks on Sunday night, Ukrainian media reported. At around 11 PM, the Air Alert app sent notifications urging residents to seek shelter due to a “radiation threat” and a “chemical attack.” It also warned of “street battles” in Kiev. According to screenshots shared by Ukrainian media, one of the messages read in Russian: “Don’t worry, Oreshnik is coming,” referring to Russia’s nuclear-capable intermediate-range ballistic missile. The Ukrainian Air Force urged residents to rely only on official sources. “The Air Alert app may have been compromised by hostile actors. There is no radiation threat!” it said in a brief statement on Telegram.
