CompTIA Security+ (SY0-501) — Question 737

Which of the following attacks can be used to exploit a vulnerability that was created by untrained users?

Answer options

• A. A spear-phishing email with a file attachment.
• B. A DoS using IoT devices
• C. An evil twin wireless access point
• D. A domain hijacking of a bank website

Correct answer: A

Explanation

Option A is correct because spear-phishing emails often target untrained users to trick them into opening malicious attachments. The other options, while they represent different types of attacks, do not directly exploit vulnerabilities stemming from user error or lack of training.
