Hackers sent fake letters from Ukrainian Parliament Chairman on Constitution changes

Hackers sent fake letters from a Russian server on behalf of the Chairman of the Ukrainian Parliament Mr. Groisman. The letters advertised the necessity of adoption of a new Constitution of Ukraine (supported with  a video record of the notorious Party of Regions MP Oliynyk, who is in hiding after 2014). The speaker's mailbox was not hacked; the hackers just found a way to evade spam filters that normally blocks such letters.
