The Computer Emergency Response Team of Ukraine (CERT-UA) says Russian hackers are targeting various government bodies in the country with malicious emails supposedly containing instructions on how to update Windows as a defense against cyber attacks.

CERT-UA believes that the Russian state-sponsored hacking group APT28 (aka Fancy Bear) sent these emails and impersonated system administrators of the targeted government entities to make it easier to trick their targets.
