This is generally not true. There are two types of mobs: those with a green icon are passive and will only attack when you attack them, and those with a red icon, which are aggressive and will attack you as long as your level is not 10 or more above theirs when they detect you.

Another thing to note is that there are generally two types of detection for a mob: Sight, which is a cone in the direction they are facing (look for the arrow on their circle if you have them targeted,) or Sound, which will detect you within a certain radius if you are running (I've heard that walking will make them not attack, but my experience is mixed at best.)

If you are in a group, then monsters will be linked, which can be seen as a line connecting monsters when you target them. You may be attacked by passive monsters when attacking aggressive monsters because they are linked.
