Ukrainian civilians on Wednesday grappled for a second day of widespread cellular phone and Internet outages after a cyberattack, purportedly carried out by Kremlin-supported hackers, hit the country’s biggest mobile phone and Internet provider a day earlier.
Two separate hacking groups with ties to the Russian government took responsibility for Tuesday’s attack striking Kyivstar, which has said it serves 24.3 million mobile subscribers and more than 1.1 million home Internet users. One group, calling itself Killnet, said on Telegram that “an attack was carried out on Ukrainian mobile operators, as well as on some banks,” but didn’t elaborate or provide any evidence.
