Just happened now: cheater on DayZ Standalone (PC) official server 5.62.99.50:10900 DE 3839
Location on map: Pushtoshka (South Western Forest Edge).
Got shot by a cheater while hiding in the forest - had no knowledge of my whereabouts, because they had previously just shot the Fuel Station to the South of the city and I move in closer to see them.
Then I ran deeper into the forest and when I decided to move to another tree (coming again back to the edge of the forest) I got shot - through thick vegetation & without any possibility to be visible to the shooter (so obviously they saw me with the cheat code).
I have video evidence
