GCIH · Question #3
Which of the following statements are true about worms? Each correct answer represents a complete solution. Choose all that apply.
The correct answer is A. Worms cause harm to the network by consuming bandwidth, whereas viruses almost B. Worms can exist inside files such as Word or Excel documents. D. Worms replicate themselves from one system to another without using a host file. Worms self-replicate across networks without a host file, can reside in document files, and consume bandwidth - while keystroke logging is a Trojan trait, not a worm trait.

Why each option
Worms self-replicate across networks without a host file, can reside in document files, and consume bandwidth - while keystroke logging is a Trojan trait, not a worm trait.
Worms spread autonomously across networks and consume bandwidth through rapid replication and propagation, whereas viruses attach to existing host files and primarily cause harm by corrupting or modifying those files on a local system.
Certain worm types, specifically macro worms, embed themselves inside document files such as Microsoft Word or Excel spreadsheets and execute via the document's macro scripting engine when the file is opened.
Keystroke logging is a feature characteristic of Trojans and spyware, not worms - worms are primarily designed for self-replication and propagation rather than capturing and recording user input.
Worms are self-contained executable programs that replicate and move from system to system over the network independently, without needing to attach to or infect a pre-existing host file - this is the primary distinction between worms and viruses.
