What is SMS phishing (smishing)?
Smishing, a blend of “SMS” and “phishing,” refers to fraudulent attempts to obtain sensitive information through text messages. These smishing attacks often lure victims by pretending to be legitimate organizations. Attackers send deceptive SMS messages that prompt recipients to reveal personal information or click malicious links. Smishing is similar to voice phishing, where cybercriminals use phone calls to impersonate reputable entities like banks or customer service representatives to deceive individuals.
For example, you might receive a text message from what appears to be your bank asking you to verify your account information. This tactic is a common method to steal sensitive data, such as login credentials and financial information.
The difference between phishing and smishing
Phishing generally involves fraudulent emails, while smishing specifically targets mobile phones through SMS messages. Both phishing and smishing aim to deceive individuals into divulging sensitive information. However, smishing leverages the immediacy and perceived trustworthiness of text messages. Unlike emails, SMS messages are often read quickly, making recipients more susceptible to scams.
While smishing uses SMS, other phishing methods like vishing use phone calls to deceive individuals.
For instance, a smishing message might appear as a notification from a delivery service, prompting you to click a link to reschedule a delivery. This will ultimately lead to a fake website designed to steal your information.
This understanding of smishing is crucial for protecting your sensitive information from sophisticated social engineering attacks. Always verify the authenticity of SMS messages, especially those requesting personal or financial details. Awareness and caution are key to preventing smishing attacks and safeguarding your data.
How smishing works and spreads
1. How smishing attacks are delivered
Smishing attacks are delivered through fraudulent SMS messages designed to trick recipients into revealing sensitive information. These messages often contain malicious links that direct users to fake websites where they are prompted to enter personal or financial information. The attackers exploit SMS vulnerabilities to make these messages appear legitimate, often mimicking trusted organizations. Users must be cautious, especially when receiving unexpected messages. Businesses must also consider compliance with data protection regulations when implementing SMS authentication to enhance SMS security.
Smishing messages can also include deceptive text messages that claim to be from financial institutions or government agencies. These messages typically urge recipients to act immediately, such as verifying their bank accounts or logging into their online accounts. Fraudsters manipulate victims into providing sensitive data without verifying the message’s source by creating a sense of urgency.
2. Role of text messages in smishing attacks
Text messages play a critical role in phishing attacks, serving as the primary medium for delivering fraudulent content. SMS messages are particularly effective for phishing because they are perceived as more personal and trustworthy than emails. This trust makes it easier for attackers to deceive recipients into clicking on malicious links or providing sensitive information.
Fraudulent SMS messages often use social engineering tactics to exploit human psychology. For example, a smishing message might pretend to be a notification about a package delivery or a security alert from a bank. These messages can contain a verification code or a request for login credentials, aiming to capture sensitive information.
3. How fraudsters obtain mobile numbers
Fraudsters obtain mobile numbers through various means, often involving data breaches and social engineering. One common method is phishing attacks, where attackers trick individuals into revealing their phone numbers. Once obtained, these numbers are used to target victims with personalized messages in smishing attacks.
Another way fraudsters gather mobile numbers is by purchasing lists from data brokers, including phone numbers collected from various sources, including social media and online transactions.
Additionally, fraudsters may use automated tools to generate and test phone numbers. This brute force attack technique involves sending smishing messages to many randomly generated numbers, hoping that some will be active. Protecting personal phone numbers and being cautious about sharing them online can help reduce the risk of falling victim to smishing attacks.
The risks of smishing attacks
Identity theft and exposure of sensitive data: Smishing attacks, a type of SMS phishing, can cause severe identity theft. Attackers use deceptive text messages to access sensitive information, including personal details, login credentials, and financial data.

This information can then be used for identity theft or other malicious purposes.
3. Government agency impersonations: Some smishing attacks involve messages that appear to be from government agencies, such as the IRS or local authorities. Unless the recipient clicks a link or provides sensitive information, these messages may threaten legal action. The goal is to scare victims into divulging personal details or making immediate payments.
4. Tech support scams: Victims receive messages claiming a problem with their device or software. The message includes a link to a fake tech support site or a phone number to call. Once contact is made, the attacker may install malware on the victim's device or charge for unnecessary services.
