## Summary

A cyber-attack compromised a Ukrainian emergency alert app on Sunday night, sending false warnings of nuclear strikes, chemical attacks and street fighting. The incident caused unease but many people doubted the messages, and Ukraine’s Air Force said within 15 minutes that there was no radiation threat.

The alerts included Russian-language messages and a link to a Telegram channel apparently run by hackers; an expert warned that clicking it could expose people to disinformation, phishing or data breaches. It took more than an hour for all-clear messages to arrive. The incident’s impact was limited, but it highlighted security weaknesses in systems used by millions amid years of frequent air-raid warnings.
