Massive cyberattack cripples Ukraine's mobile operator amid escalating war

A massive cyberattack targeted Kyivstar, one of Ukraine's major mobile phone and internet providers, and at least one bank in Kyiv, just as Ukrainian President Volodymyr Zelensky sought urgent U.S. aid during his visit to Washington. The attack highlighted the ongoing threat to Ukraine's statehood, as political infighting in the U.S. risks cutting off aid to Ukraine. Zelensky emphasized the importance of U.S. support in countering Russia's aggression, as the war in Ukraine combines trench warfare with high-tech weaponry. The cyberattack disrupted communication and internet services, affecting millions of subscribers. Ukraine's intelligence service is investigating the possibility of Russian involvement. The uncertainty surrounding Western aid has increased anxiety in Kyiv, where decreased assistance could pose an existential threat.
