It doesnt need any user intervention.A worm does not need to attach itself to an existing program. Worms always cause at least some harm to the network, even if only by consuming bandwidth.

Trojan Horse:
Trojan are used to get remote access to a target computer system. Once a Trojan has been installed on a target computer system,we may have access to the computer remotely and perform various operations, limited by user privileges on the target computer system and the design of the Trojan.

RAT:
A Remote Administration Tool (a RAT) is a piece of software that allows an operator to control a system as if he has physical access to that system. The operator controls the RAT through a network connection. It is very similar to trojans.
