Exam 200-201 topic 1 question 83 discussion

The intruder used "social engineering" to trick the user into clicking a harmful link in an email, which allowed them to access the corporate network. Social engineering involves manipulating people to gain unauthorized access or information.

A. Social Engineering Method (Phishing Attack)

Since Phishing is not an answer I think social Engineering is the best option. Also there's a typo in the question "fink" should be "link".

here I think would be phishing but yeah A is the best option

The only problem here is that Social Engineering is not a "testing method" it is an attack. But the other alternatives are wrong, so (A) is correct. Social engineering attacks leverage the weakest link, which is the human user. If the attacker can get the user to reveal information, it is much easier for the attacker to cause harm rather than use some other method of reconnaissance. This could be done through email or misdirection of web pages, which results in the user clicking something that leads to the attacker gaining information. Social engineering can also be done in person by an insider or outside entity or over the phone.
