Friend is sitting in base on server and gets randomly message on screen saying "you are dead" I then logged onto the server to see what has happened then i find his body in the base which has been completely stripped and looted. I go to check the door assuming that we have been raided and someone is in the base but no the door is completely shut and locked and nobody has touched the crates in the base yet they have somehow looted my buddy. 10 seconds later i get the same message "you are dead" when there are no windows or anything near me. This is the first hacker I have encountered in a long time

This happened on 24/08/2023 at 3.58pm uk time.
Server 195.82.158.42:11100 EU DE 1390

Thanks for your help if possible
