According to police officers, hackers created a mailbox, using the Anonymizer and worked from the territory of Russia.
It turned out that they sent fake emails on behalf of Interior Minister Arsen Avakov. Emails contained rules of conduct for police officers during the elections. In addition, the police were required to take certain actions in favor of one of the candidates.
On the Internet, there is an opinion that the news is fake. Many people know that real hackers do not even need to create a mail to send messages. They can go to the server of the police and send emails directly. And can do it from any other host on which the port number 25 is open, intended for the SMTP protocol.
Perhaps citizens of Ukraine decided to joke this way. They just installed a browser with VPN and created mail. That’s enough to hide location. Moreover, this incident was another reason to accuse Russia of intervening in the Ukrainian presidential election.
