Overview
- Ukrainian authorities confirmed that the national "Alerte aérienne" mobile app was compromised and circulated false alerts to users.
- The communications group Spravdi published screenshots showing Russian‑language messages, references to "Orechnik," and claims of radiation and chemical threats and attributed the intrusion to Russian actors.
- Officials said the country's national alert infrastructure and a separate Kyiv app remain operational and urged citizens to follow official military channels, enable emergency phone notifications, and heed sirens.
- The incident followed the end of a localized humanitarian truce near Olechky and is being investigated by authorities while they work to stop further false messages.
- The breach endangers civilians by undermining trust in short‑notice warnings that give people only minutes to seek shelter and could intensify information warfare tactics used in the conflict.
