Ukraine security app hacked as longest-running truce with Russia ends

Ukraine’s air raid alert system was hacked by ‘hostile interference’ on Sunday, moments after the ceasefire with Russia ended over eastern Kherson.

The Air Force and anti-disinformation centre said they suspected the country’s air raid alert system had been hacked after false alerts of a radiation threat appeared on the application.

“The Air Alarm application has probably been subjected to hostile interference,” the force said in a message.

“There is no radiation threat.”

Air Force spokesman Yuriy Ignat confirmed to the Agence France-Presse (AFP) news agency that the app was hacked.

SPRAVDI, Ukraine’s Centre for Strategic Communications, blamed Russia for the hack in a post on its X account.

A separate app, which deals specifically with the Ukrainian capital, is still working normally, the Kyiv city authorities said.

‘Temporary’ Kherson truce over

The hack came after the longest truce of the Ukraine war ended.

The ceasefire, limited to the eastern Kherson region, ended on Sunday after Russia refused the offer of an extension, Ukrainian officials said.

The rare pause in fighting, brokered by US first lady Melania Trump and which began early Tuesday, enabled a humanitarian mission to the Russian-occupied city of Oleshky as the war grinds through its fifth year.

Neither side reported violations after the truce began, in what one Ukrainian politician described as the “biggest de-escalation since 2022”.

“The ceasefire, which was in effect from October 27 to November 1, has ended,” said Ukraine’s parliament commissioner for human rights, Dmytro Lubinets.

He called the temporary truce “an important step in our joint humanitarian efforts” with Russia.

US-mediated talks between Russia and Ukraine are set to resume this month, having been effectively frozen since the United States and Israel launched joint strikes on Iran in February.

On Sunday, Ukrainian President Volodymyr Zelenskyy said his country would stop hitting Russian oil refineries, as US counterpart Donald Trump has demanded, if the US provided Ukraine with powerful Patriot interceptor missiles.

Since Russia’s full-scale invasion in early 2022, the conflict has destroyed parts of eastern and southern Ukraine, left hundreds of thousands of soldiers and civilians dead, and forced millions to flee their homes.

AFP spoke to several Kherson residents, one of whom said the ceasefire had been a “breath of fresh air”.

“We have to use this time to get things done,” said Volodymyr Omeltchenko, a 38-year-old gardener.

“We’re pruning the rose bushes for winter.”

Pope Leo, who had pressed Russia for a truce in Oleshky, said he hoped the temporary pause would “strengthen the desire for dialogue and lead to new concrete peace initiatives”.

A Ukrainian military officer, speaking on condition of anonymity, expressed concern that the fighting would be “worse than before” when it resumed.

Russian forces on the other side of the Dnipro river, had taken advantage of the calm of the past few days to amass new troops, transport ammunition stocks, and collect intelligence on Ukrainian positions using surveillance drones, the officer said.

Ukraine strikes Russian oil refinery

Russia and Ukraine exchanged strikes on Sunday.

Russia said a drone had struck an “industrial enterprise” east of Moscow overnight.

Ukrainian media reported that its military had attacked the Kstovo oil refinery, calling it “one of Russia’s largest oil refineries, producing fuel and lubricants”.

Ukraine has repeatedly struck Russian oil and gas sites, in what it says is fair retaliation for Russian attacks on Ukrainian energy infrastructure.

Trump has been pressing Ukraine to stop such attacks, blaming them for rising diesel costs that analysts attribute to the Iran war.

On Sunday, Zelenskyy referred to conversations he had had with Trump and his team on the issue, in an interview with Fox News.

“We said that if you want us not to attack Russia’s refineries, they have not to attack our energy system. Another alternative, give us Patriot missiles, we will find money, not just aid,” he said.

Ukraine’s energy ministry reported fresh power outages across the country Sunday, including in Kyiv, following Russian strikes on Ukrainian energy infrastructure.

Ukrainian strikes killed five people in Russian-occupied Ukraine between late Saturday and Sunday afternoon, Russian-installed authorities said.

Both Russia and Ukraine deny targeting civilians.

Russia now occupies around a fifth of its neighbour: the Crimean peninsula, which it annexed in 2014, most of the eastern regions of Donetsk and Lugansk and large parts of the southern Zaporizhzhia and Kherson regions.
