The answer is smishing, a phishing attack conducted via SMS. This is correct because the attack vector is a text message impersonating the mobile carrier, using urgency—threatening suspension—to trick the user into clicking a malicious link and confirming an MFA code, which captures credentials or bypasses multi-factor authentication. On the Security+ SY0-701 exam, this scenario tests your ability to distinguish smishing from other social engineering variants like vishing (voice) or spear phishing (targeted email); a common trap is confusing it with vishing since both involve urgency, but the key is the SMS medium. Remember the memory tip: “SMS + phishing = smishing,” and if the message arrives via text, it’s always smishing, not email or phone call.
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 help desk technician receives an SMS claiming to be from the mobile carrier. The message says the user's corporate number will be suspended unless they open a link and confirm an MFA code. The user has not reported any account issues. What attack is this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Smishing
Smishing is a phishing attack conducted via SMS (Short Message Service). The message impersonates the mobile carrier, creates urgency by threatening suspension, and lures the user to a malicious link to capture MFA codes or credentials. Since the attack vector is SMS, not email or voice, this is smishing.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Spear phishing
Why it's wrong here
Spear phishing is targeted deception, but this message is specifically delivered by text message rather than email or another channel.
✓
Smishing
Why this is correct
Smishing is phishing delivered through SMS, and the attacker is using urgency and a fake carrier notice to steal credentials or MFA codes.

✗
Vishing
Why it's wrong here
Vishing uses voice calls, such as a phone conversation with a fake support agent, not a text message link.
✗
Baiting
Why it's wrong here
Baiting typically tempts a victim with something enticing, like free media or hardware, rather than a service suspension warning.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing the delivery method (SMS vs. email vs. voice) — candidates often pick 'spear phishing' because the message is personalized, but the defining characteristic is the SMS channel, which makes it smishing.
Detailed technical explanation
How to think about this question
Smishing exploits the trust users place in SMS as a legitimate communication channel, often using URL shorteners or typosquatted domains to evade basic filters. Attackers may also use SIM swapping or SS7 protocol vulnerabilities to intercept MFA codes sent via SMS, making this attack particularly dangerous for corporate accounts.

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.
