KIEV (Reuters) - Hackers likely controlled by Russia are stepping up efforts to disrupt Ukraine's presidential election in March with cyber attacks on electoral servers and personal computers of election staff, the head of Ukraine's cyber police said on Friday.
Serhiy Demedyuk told Reuters the attackers were using virus-infected greeting cards, shopping invitations, offers for software updates and other malicious "phishing" material intended to steal passwords and personal information.
