- A
Spear phishing
Why wrong: Spear phishing is a targeted version of phishing aimed at a specific individual or organization. While the email is sent to an employee, the question does not provide evidence of tailored content or reconnaissance, so the broader category 'phishing' is more appropriate.
- B
Phishing
Phishing is a social engineering attack that uses deceptive emails and malicious attachments to trick recipients into executing malware or revealing sensitive information. The typo-squatted sender address and executable attachment are classic indicators of a phishing attempt.
- C
Smishing
Why wrong: Smishing (SMS phishing) uses text messages rather than email. Since the attack vector is email, smishing does not apply.
- D
Vishing
Why wrong: Vishing (voice phishing) uses phone calls or voicemail messages. The attack described involves an email attachment, so vishing is not correct.
SY0-701 Threats, Vulnerabilities, and Mitigations Practice Question
This SY0-701 practice question tests your understanding of threats, vulnerabilities, and mitigations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A security analyst receives an alert from the email security gateway about a message sent to an employee. The email has an attachment named 'Invoice_Q4_2024.exe'. The employee claims they did not open the attachment, and the email appears to come from a known vendor's domain but the sender address has a slight typo. Which type of attack is most likely being attempted?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"most likely"Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Phishing
The email contains a malicious executable attachment ('Invoice_Q4_2024.exe') and uses a spoofed sender address with a typo to impersonate a known vendor. This is a classic phishing attack because it is a broad, unsolicited attempt to trick the recipient into executing malware, without any personalized targeting beyond the generic invoice lure. The slight typo in the sender domain indicates domain spoofing, a common phishing technique that exploits the lack of SPF/DKIM validation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the distinction between phishing and spear phishing by including a generic lure (like 'Invoice_Q4_2024.exe') that lacks personalization, which immediately disqualifies spear phishing even if the sender appears to be a known entity.
Detailed technical explanation
How to think about this question
The .exe attachment is a portable executable file that, when executed, can install malware such as a remote access trojan (RAT) or ransomware. The typo in the sender domain (e.g., 'vend0r.com' instead of 'vendor.com') exploits the fact that many email clients display only the display name, not the full SMTP envelope address, making it easy for users to miss the spoof. Modern email security gateways use Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) to detect such spoofing, but if the vendor's domain lacks these records, the attack can bypass basic filters.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An employee at a financial services firm receives an email that appears to come from the IT helpdesk, asking them to reset their password via a link. The link leads to a convincing fake portal that harvests credentials. Security teams use phishing simulations and security-awareness training to reduce this attack vector. Questions like this test whether you can identify social engineering techniques and appropriate controls.
