Killed by a hacker, but....

[s2ua7 12]

So my character of 8 days in game was killed by a hacker who completely bombarded my building with either grenades or satchel charges... Not sure which. All I know is that the building I was in suffered 5 or 6 explosions and then fell to the ground... Now I am not mad about the hacker as I felt it was about time to start a new character, but I am curious as to how to ID a hacker.

So as I was minding my own business, I noticed someone come into the building I was currently occupying... Knowing that there was a hacker on the server I was in "shoot first, ask questions later" mode. I managed to kill the guy that came in, but it did not register on the debug screen (he was clearly dead). When I studies his body it gave me a name and I could not loot his body. In fact, when I tried to take the 24 slot backpack from him, it removed my backpack and it completely disappeared. I could not loot the entrenching tool. Now this person correctly identified the ammo and that I was firing (on a sever of 10-15) from my gun even though I was laying down in a room with no windows, so that is what leads me to suspect he was a hacker along with his name on the body with the glitched/hacked equipment

Now I am not going to name and shame as I am not sure if he was just glitched as he claimed but here are my questions.

1. Can a hacker change how his name appears when one studies a dead body?

2. Is not being able to loot a body a glitch or a sign of a hacker as this player suggests?
