Difference between active and passive threats?

Passive attack:

So in passive attack a hacker intrudes your system, and waits for some valuable information.

An example could be: A keylogger which sends the input given by the victim to a hacker via a network(LAN or internet whatever).

Active attack: In an active attack a hacker tries to get the valuable information by using his abilities rather than depending on the stupidity of the victim.

An example could be: Using Brute force to crack the passWord of a system.
