Question 7

A nurse receives an e-mail containing a web address hyperlink on his or her personal computer. The e-mail instructs the nurse to go to the website to confirm his or her bank account number. When the nurse clicks on the link, it would take him or her to a phony website. This is an example of:
A) Pharming.
B) Worm.

C) Pharming and E) Phishing are types of cyberattacks aimed at stealing personal information, not viruses.

Question 19

Which characteristics would be associated with spyware?
A) Random pop-up advertisements that occur when using a program
B) Ability to monitor keystrokes to send to a third party
C) Maintenance of default home pages on web browsers
D) Inability to scan the hard drive

Accepted Answer

Spyware is designed to monitor user activity, such as keystrokes, and send this information to a third party without the user's consent.

Question 20

A nurse is checking the nurse's e-mail and finds the following: "If you have a file named 'workline' on your computer, delete it immediately. The file contains a virus that will be released in 5 days and destroy your hard drive." The e-mail goes on to describe how to delete the file. The nurse interprets this as:
A) A damaging hoax.
B) An urban legend.
C) A Trojan horse.
D) Spyware.

Accepted Answer

This email describes a typical hoax scenario, where recipients are falsely alarmed about a non-existent virus in a file named 'workline' and instructed to delete it. Such hoaxes often cause unnecessary panic and can lead to the deletion of important files or adherence to unnecessary procedures, but they do not directly harm systems like actual malware would.
