A worm typically spreads via which method?
Portable media (USB, CDs, floppy disks)
Vulnerabilities in software
Websurfing on the internet
User negligence
The correct answer is 'Vulnerabilities in software'. A worm is a type of virus that spreads (replicates) itself from computer to computer without human interaction. This happens due to software vulnerabilities, whether application or OS level. The other 3 answers involve human interaction.
Edit: sorry but the answer doesn't sense. Firstly, a worm spreads on it own. Hence the answer should be automatic. Secondly, "Vulnerabilities in software" doesn't make much sense: do you regard pushing mail a vulnerability? This question was cooked up to distinct human interaction is needed or not without clearly defining what human interaction is. A poor question in my POV.
