Several coworkers in the sales department received an email claiming to be from you. each message was personally addressed and contained a link to a "test site" and a request to log in with normal user credentials. you never sent it, and on examination, the supposed test site is a phishing scam. just what variant of phishing is this?
spear phishing
vishing
pharming
whaling

The correct answer is A.

Explanation:

Vishing can be described as phishing but only using a mobile telephone, making the victim give up any personal information that could be used for identity theft etc.

Pharming is a process which redirects the traffic from a known and trusted website to another one where they perform the operation of stealing the personal information of the people.

The example given in the question falls into the category of "Spear Phishing" which is when the victim receive e-mails that look like they have been sent by a trusted and known individual. This way they are more likely to open the e-mail or click on the link in the e-mail and the phishing act has a higher chance of success.

I hope this answer helps.
