KYIV (Reuters) -A massive cyberattack warning Ukrainians to "be afraid and expect the worst" hit government websites late on Thursday, leaving some websites inaccessible on Friday morning and prompting Kyiv to open an investigation.
Ukraine's foreign ministry spokesperson told Reuters it was too early to say who could be behind the attack but said Russia had been behind similar strikes in the past.
The cyberattack, which hit the foreign ministry, the cabinet of ministers and the security and defence council among others, comes as Kyiv and its allies have sounded the alarm about a possible new Russian military offensive against Ukraine.
"It's too early to draw conclusions, but there is a long record of Russian (cyber) assaults against Ukraine in the past," the foreign ministry spokesman told Reuters.
