The answer is smishing, because the attacker uses SMS text messages as the delivery vector to trick the recipient into clicking a malicious link. This is a form of social engineering that exploits the trust users place in text-based communications from known entities like mobile carriers, often leading to credential theft or malware installation. On the Security+ SY0-701 exam, this scenario tests your ability to distinguish smishing from other social engineering variants like vishing (voice calls) or phishing (email), with the key differentiator being the SMS channel. A common trap is confusing smishing with spear phishing, but remember that smishing specifically relies on text messages sent to mobile devices. Memory tip: think “SMS + phishing = smishing,” where the “S” in SMS reminds you it’s a text-based attack.
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.
An employee gets a text message saying their mobile carrier will suspend service unless they tap a link and verify their account details. What type of 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, because the attacker is using SMS messages to trick the user
This is smishing because the attacker uses SMS (Short Message Service) as the delivery vector to send a fraudulent message that tricks the recipient into clicking a malicious link. Smishing is a form of social engineering that exploits the trust users place in text-based communications from known entities like mobile carriers, often leading to credential theft or malware installation.
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.
✓
Smishing, because the attacker is using SMS messages to trick the user
Why this is correct
Smishing is phishing delivered through text messages, often with urgent account or delivery claims.
Related concept
Read the scenario before looking for a memorised answer.
✗
Vishing, because the attacker is using a voice call to pressure the user
Why it's wrong here
Vishing uses a phone call or voice channel, not a text message with a link.
✗
Baiting, because the attacker is offering a free service upgrade
Why it's wrong here
Baiting usually relies on a tempting lure, while this message uses urgency and account fear.
✗
Tailgating, because the attacker is trying to enter a building behind someone else
Why it's wrong here
Tailgating is a physical access attack and has nothing to do with SMS messages.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse smishing with vishing because both involve phishing via telecommunications, but the key differentiator is the medium: SMS (text) versus voice call.
Detailed technical explanation
How to think about this question
Smishing attacks often use URL shorteners or typosquatted domains to hide the true destination, and the SMS may spoof the sender ID (e.g., using a short code or alphanumeric sender) to appear legitimate. In a real-world scenario, the attacker might harvest two-factor authentication codes by directing the victim to a fake carrier login page that proxies the real authentication flow.

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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A worker receives a text message from someone claiming to be the company's HR partner. The message says a benefits portal issue will be fixed only if the worker clicks a link and logs in right away. What type of attack is this most likely?
easy
✓ A.Smishing, because the attack is delivered by text message.
B.Watering hole, because the attacker compromised the HR partner's website.
C.Spoofing only, because the attacker copied the HR logo in the message.
D.Port scanning, because the attacker wants to find open services on the phone.
Why A: This is smishing because the attack vector is a text message (SMS) that attempts to trick the recipient into clicking a malicious link and providing credentials. Smishing is a form of social engineering that exploits the trust in SMS communications, often impersonating a legitimate entity like HR to create urgency. The goal is credential theft, not technical exploitation of the phone's services.
Variation 2. Users in a warehouse report an SMS claiming a missed delivery. The link opens a login page that closely matches the company portal, and several users later receive unauthorized password reset emails. What attack is most likely?
medium
✓ A.Smishing, because the malicious lure is delivered through text messaging.
B.Vishing, because the attackers are likely trying to get a callback from the victims.
C.Spear phishing, because the message appears customized for warehouse employees.
D.Baiting, because the fake delivery notice tempts users to click for a reward.
Why A: The attack is smishing because the initial lure is delivered via SMS (Short Message Service), directing victims to a fraudulent login page. This aligns with the definition of smishing, a form of phishing that uses text messages to trick recipients into revealing sensitive information. The subsequent unauthorized password reset emails confirm credential compromise, which is the typical goal of smishing attacks.
