Ataques russos cortam energia para milhares na Ucrânia enquanto cessar-fogo em Kherson termina Publicado há 19 horas.

Ukraine and Russia have both said air alert apps were hacked on Sunday night after fake messages warning of attacks, including nuclear, were sent to users.

O aplicativo amplamente utilizado na Ucrânia enviou alertas de nível vermelho de bombardeio aéreo por todo o país, com alertas adicionais de radiação, ataques químicos e combates de rua enviados a alguns residentes em áreas incluindo Kyiv.

A few hours later, Russian authorities said a similar app was hacked after fake alerts, some of which contained foul language, were triggered.

It was unclear who was behind the cyberattacks or whether the two incidents were connected.

Muitos cidadãos ucranianos estão acostumados a receber alertas quase noturnos avisando sobre ataques de mísseis e drones russos. Alguns disseram à BBC que, após quatro anos e meio de guerra, desativaram o app por completo.

After Sunday night's hack, the country's air force urged people to consult other official channels.

The government said it had temporarily disabled the app for maintenance, saying it had "apparently been compromised.

Some of the fake warnings were written in Russian, which would have alerted many users to the fact they were not legitimate.

Mas Olena, moradora de Kiev, disse ao programa Today da BBC Radio 4 que estava alarmada, dizendo: 'O primeiro pensamento foi 'oh meu Deus, eu não estou preparada para isso.

I'm prepared for blackouts, for a cut in central heating and water supply, but not for nuclear attack.

Olena says her husband then received alerts for "street fighting attacks in Kyiv" and another alert, written in Russian.

After that I understood that somebody had attacked the app, because all notifications we get in Ukrainian.

In Russia, the government said one of its air raid alert apps had also been targeted by "a massive cyberattack", which sent "fake information to the public.

It warned some users that "nuclear warheads mounted on P1-Suns [a Ukrainian attack drone] had been launched at all regions of Russia.

The alert, which included profanities, opened with a message telling residents there was a "risk of [things] getting lively" and told them to "stock up urgently on food for three weeks and hide.

Na manhã de segunda-feira não havia sensação de que as mensagens causaram pânico generalizado na Rússia, e o incidente não teve destaque nas mídias.

Asked about the breach, Kremlin spokesman Dmitry Peskov did not address it specifically but said all Russian government internet resources were "one way or another.

sob ataques cibernéticos constantes, incluindo o site presidencial, que é alvo "24 horas por dia.

He said the proliferation of AI technology was contributing to an increase in cyberattacks.

Russia's emergencies ministry said on Monday that the app's "full functionality will be restored by the end of the day" and the hack had not impacted the wider alert system.

Embora se acredite amplamente que a Rússia e a Ucrânia realizam ataques cibernéticos um contra o outro, a linguagem informal usada nos alertas falsos no domingo apontou para os chamados grupos hacktivistas, que poderiam estar alinhados a Moscou ou a Kiev, mas não são formalmente dirigidos por nenhum dos governos.

Those responsible for the hack on Russia's system have likely had the capability to launch such an attack for some time but decided to hold off until Ukraine's alert app was compromised, cyber experts told the BBC.

Oleksander Merezhko, chair of the foreign affairs committee in the Ukrainian parliament, said the attack did not cause panic or extreme reactions.

Merezhko disse à BBC que os ucranianos, especialmente em Kiev, estavam acostumados a 'alertas praticamente ininterruptos', acrescentando 'esta mensagem estava em língua russa, o que imediatamente despertou suspeitas.

He continued: "It's a very unpleasant fact but it is part of cyber war and people in Ukraine understand that. It is possible and we are quite prepared for such possibilities.

Herbert Lin, a senior research scholar for cyber policy and security at Stanford University, told BBC World Service's Newsday programme: "I think it's the first time [a hack of this kind] happened to an official Ukrainian information app, but I suspect it won't be the last.

Os alertas na Ucrânia foram enviados minutos antes do fim de um cessar‑fogo localizado na linha de frente da região de Kherson, que foi implementado na última terça‑feira.

Ele havia sido mediado em parte pela Primeira Dama dos EUA, Melania Trump, para permitir que civis evacuassem a cidade ocupada pelos russos de Oleshky.

Fighting continued elsewhere while the Kherson ceasefire was in place. In the city of Dnipro alone, 15 people were killed in an attack on a train platform on Thursday.

Russia launched a full-scale invasion of Ukraine in February 2022.
