Or in authoritarian regimes it often means "stole from the party". As long as you only steal from the poor and give the proper bribes up the chain you are in no danger in most corrupt societies. Except possibly in the rare occasion where your corruption causes a disaster that embarrasses the people above you in the hierarchy.

Far too often when you see stories about how someone was persecuted for corruption it boils down to "he stole from rich people".

This is true in any power structure ever. Kings, mafia, pick-your-dictatorship, many democracies. Hurt or steal from the poor, not other rich or elite, and always make sure to kick some up to the big guys.
