Which two characteristics describe a worm? (Choose two.)
- hides in a dormant state until needed by an attacker
- infects computers by attaching to software code
- executes when software is run on a computer
- is self-replicating
- travels to new computers without any intervention or knowledge of the user
Explanation: Worms are self-replicating pieces of software that consume bandwidth on a network as they propagate from system to system. They do not require a host application, unlike a virus. Viruses, on the other hand, carry executable malicious code which harms the target machine on which they reside.
