Question

Worms require an executable (a running program) to spread, attaching to other executables.

a. True
b. False

Answer 1

False.

Worms, unlike viruses, do not require a running program. Worms take advantage of security vulnerabilities to spread automatically. They install malicious code and move to other machines and you do not do anything to make them spread. Some worms are able to scan themselves and install on vulnerable systems with incredible speeds.
