My friend and I were in the middle of the woods hunting an animal for food, west of Khelm and north/northwest of Druzhba. All of a sudden we are both killed within seconds of one another, from what I assume is a hacker because of no gunshot or cracks. No indication of any other players being around us before this. I died in 2 hits from something, instantly dead without unconsciousness. My friend died instantly in 1 hit about 2-3 seconds after I died.
