Why Russia’s latest cyberattack on Ukraine is a desperate attempt to sow panic
On Sunday night, millions of Ukrainians were sent an alert to their phones that would usually spark panic and fear.
Citizens were told that there was an imminent threat of radiation, chemical attacks and fighting on the streets of Kyiv through an app used to by the government to issue nationwide notifications in emergencies.
It was quickly followed up with a clarification that the system had likely been hacked by Russia and that no such threat existed.
“The Air Alarm application has probably been subjected to hostile interference,” read a follow-up message on Telegram. “There is no radiation threat! Stay calm and follow our updates on our channel.”
Shortly after, Russia told its citizens that Ukraine had hacked its systems to warn its people of imminent nuclear strikes.
Neither countries have claimed responsibility and it is unclear where or how the incidents were sparked. But they have been widely interpreted by officials and analysts as tit-for-tat attacks, started by Russia.
A hacker within the Ukrainian “hacktivist” community told the BBC that the breach of the Russian alert system was likely to be a “retaliatory attack” by Ukraine.
The ensuing chaos has laid bare the increasingly devastating impact of cyberattacks.
According to the Ukrainian security service (SBU) , citing its cybersecurity department, more than 16,000 Russian cyber attacks and “critical cyber incidents” had been neutralised between the start of the war in February 2022 and July this year.
Brigadier general Volodymyr Karasteliov referred to one large-scaled DDoS arrack that lasted three hours against a nationwide Ukrainian television channel.
“The botnet generated up to 200,000 requests per minute from nodes in Asia, Europe, and the United States,” he said.
“The attack targeted the website’s application layer, with hackers imitating the behaviour of real users in an attempt to overload the server with complex requests and make the site unavailable.”
According to research published in PLOS in April 2024, Russia ranked as the number one hotspot for cybercriminals worldwide, followed by Ukraine.
Cybersecurity firm CybelAngel noted that the attacks between Russia and Ukraine are largely asymmetric. The company’s REACT team recorded 1,651 cyber incidents targeting Ukrainian entities with 575 targeting Russian entities between January 2025 and January 2026.
