An attacker crafts a message that appears to be from a trusted source, but in reality it redirects the
recipient to a malicious site where information is harvested. The message is narrowly tailored so it
is effective on only a small number of victims. This describes which of the following?

A.
Spear phishing

B.
Phishing

C.
Smurf attack

D.
Vishing

Explanation:
Spear phishing is an e-mail spoofing fraud attempt that targets a specific organization, seeking
unauthorized access to confidential data. As with the e-mail messages used in regular phishing
expeditions, spear phishing messages appear to come from a trusted source. Phishing messages
usually appear to come from a large and well-known company or Web site with a broad
membership base, such as eBay or PayPal. In the case of spear phishing, however, the apparent
source of the e-mail is likely to be an individual within the recipient’s own company and generally
someone in a position of authority.
