On Sunday night, the system delivered something to make them sit up and take note – a succession of more extreme threats that quickly escalated to impending nuclear strikes, chemical attacks and combat on the streets.

that → deliver → streets
But many in the country did not take them seriously and doubted the veracity of the messages.

"The first thing I saw was the word 'nuclear' and that made me pretty nervous and scared.

something → fly → us
"But then the notification mentioned 'street fighting in Kyiv', and I thought, wait, no, that's impossible."
The alerts included some messages written in Russian, and one included a link to a Telegram channel apparently owned by a hacker group.
Within 15 minutes, Ukraine's Air Force issued a statement saying the alert app had been compromised and clarifying there was no radiation threat.

But it took more than an hour to issue "all clear" messages.

Yevhen Baliutov, a cybersecurity expert at Kyiv School of Economics, told the BBC it was clear to him the Ukrainian alert system was hacked by Russians, saying many Ukrainians had clicked a link included with the alerts leading to a Russian Telegram channel, potentially exposing them to further disinformation, phishing attempts or data breaches.
asserted
Ukrainians → tell → disinformation
"This is a war, so it's no surprise that Russia will try to hack, will try to send us fake news, will try to manipulate, and will use that for their propaganda.

While both Russia and Ukraine are widely believed to carry out cyberattacks against one another, the informal language used in the hoax alerts on Sunday pointed to so-called hacktivist groups, which could be aligned to Moscow or Kyiv but are not formally directed by either government.

Baliutov said it was also logical that Ukraine would have responded by launching a cyber-attack on the Russian emergency alert system.

Both sides have similar capabilities in cyber warfare, he added.

Kochmar said after the initial concern, Ukrainians quickly turned to joking about the incident.

Everyone started messaging each other, discussing what was happening.

And what I found fascinating was how quickly we turned the whole thing into a joke."
Although the impact of this incident had been limited, it illustrated the weakness of a crucial system, Baliutov said.

When developing such applications, we need to consider security from the very beginning, without skipping essential security measures.
asserted
we → develop → measures
When millions of people rely on a service, we cannot afford to take shortcuts with security."
The authorities already faced the challenge of maintaining public alertness after four and a half years of war with ceaseless attack warnings sounding sometimes hourly.

warnings → rely → war
Now they must reassure people the systems in place to protect them are robust, trustworthy and should be followed.
