From the developer:
PunkBuster is a tool designed to combat cheating in some of the most popular games. It provides real-time memory scanning on player's computers searching for known hacks/cheats with frequent status reports, highly encrypted, sended to the PB Server. The PB Admins can request actual screenshot samples from specific players and/or can configure the PB Server to randomly grab screenshot samples from players during gameplay.
