In the realm of online games, an 'exploit' is usually a software bug, hack or bot that contributes to the user's prosperity in a manner not intended by the developers. In other words it is a form of cheating.

Exploits are most commonly used by two groups:

~Those who are so enthusiastic about the game that they take any advantage they can get
~Those who are so UNenthusiastic about the game that they do not care if they are banned

Oftentimes, players can make exorbitant sums of real-world money by selling duped items and game currency or exploit information to willing buyers.

Many exploits are designed to provide superuser-level access to its owner.

Oh, c'mon! Not again.
