Odd hack (something new?)

[Nagrom]

I spotted something odd whilest playing on a public VAC server today. For some reason, a player we all could see as just another terrorist, appeared to be a ghost. You could just walk right through the guy. Although he could hit (and kill) all of us, nobody was able to hit him.

Is this some kind of new hack, something old I happened to miss or some mod/command which allows the admin to do something like that (which would surprise me, as that guy was randomly attacking other players as well...).

Kind of puzzled here :s

Make sure that the server was not running AMX with/or Vexd Module, these plugins can do evrything with the game. So I think it wasn't a hack.

Still, that would mean that player was an admin, executing a few commands only an admin could use. And I don't think an admin of a what seemed to be descent clanserver would just attack everybody, wait till time-out to anno everybody...

Look what I've found on the amx site and read the description of this amx plugin:
