Hacker on DayZ ATL 4-225

We engaged a group wearing yellow armbands and one of them was speed hacking and teleporting and could see us through walls. We shot the hacker multiple times but couldn't kill him. He killed 3 of us and 2 of us survived after having shot him. He was wearing a ghillie that he took from my friend and had his Tundra.

Several of us have video/streaming of the event.
