wallhack

wallhack


   A form of game cheat especially associated with first-person shooters
   like Quake, in which the walls in the simulated maze or dungeon are
   rendered transparent to the cheater. This gives the cheater normally
   hidden information about the whereabouts of other players. Beyond
   gaming, a wallhack is the paradigm case of a whole class of security
   problems that stem from the fact that a server cannot trust client
   software, and server authors must assume that all computation farmed
   out to a client is exposed to and can be interfered with by the user.
