What Is Smishing?

What is smishing? Smishing is an internet fraud method. Unlike phishing, it does not use e-mails or Internet links to elicit sensitive information such as passwords from victims but uses SMS text messages. The messages ask the victim to visit a link, install software or call a phone number, for example. In the second step, sensitive data is stolen and misused for fraudulent purposes.

Smishing is a term used to describe a type of cyberattack that involves the use of SMS (Short Message Service) or text messages to deceive and manipulate individuals into divulging sensitive information, clicking on malicious links, or downloading malicious content.

This form of cyberattack blends elements of social engineering and phishing tactics to exploit human vulnerabilities.

What is Smishing?

Smishing is a portmanteau of “SMS” and “phishing.” It is a deceptive technique that leverages text messages, typically sent to mobile phones, to trick recipients into taking actions that are detrimental to their security and privacy. These actions may include revealing personal information, visiting fraudulent websites, or installing malware on their devices.

Smishing Key Characteristics

Methods used in Smishing attacks:

• Spoofed Sender Information: Attackers often manipulate the sender information to make it appear as though the message is coming from a trusted source, such as a bank, government agency, or well-known company.
• Urgency and Threats: Smishing messages commonly create a sense of urgency or fear, prompting recipients to take immediate action, such as providing personal details or clicking on links.
• Phishing Links: Smishing messages contain links that, when clicked, direct the recipient to malicious websites designed to steal personal information or deliver malware.
• Malware Downloads: Some smishing messages include attachments or encourage recipients to download apps or files, which can contain malware.
• Social Engineering: Smishing messages often use psychological manipulation to exploit emotions like fear, curiosity, or excitement to trick individuals into taking actions they would not otherwise perform.

Smishing: Common tactics employed by attackers

• Impersonating trusted entities like banks, government agencies, or well-known companies.
• Requesting sensitive information such as account numbers, Social Security numbers, or PINs.
• Threatening legal action or financial consequences if the recipient does not comply.
• Offering enticing deals or prizes to lure recipients into clicking on malicious links or downloading harmful files.
• Exploiting current events, news, or seasonal trends to increase the likelihood of engagement.

Smishing: Target Audience

Who are the typical targets of Smishing attacks?

Smishing attacks can target a broad range of individuals and organizations. Typical targets include:

• Individuals: Smishing attackers often target individuals who may be more susceptible to social engineering, such as the elderly or those less familiar with cybersecurity best practices.
• Employees: Employees within organizations are frequently targeted as they might have access to sensitive corporate information or financial data.

The industries and individuals at risk:

• Financial Services: Banks and financial institutions are prime targets due to the potential for financial gain.
• Healthcare: Medical facilities and healthcare professionals may be targeted due to the sensitivity of patient data.
• Government Agencies: Government institutions are at risk because they deal with sensitive information and services.
• Retail: Retail customers may receive smishing messages related to fake promotions or sales.
• Tech Companies: Individuals may receive smishing messages pretending to be from tech giants like Apple or Google.

How Smishing Works

Initial Contact

The attacker initiates the attack by sending a deceptive text message to the target’s mobile phone. The message often appears to come from a trusted source, like a bank, government agency, or well-known company. The sender’s information is often spoofed to appear legitimate.

Bait

The message contains bait in the form of an enticing offer, urgent request, or a threat. This bait is designed to capture the recipient’s attention and elicit a response. For example, it may claim that the recipient has won a prize, needs to verify their account, or is facing dire consequences if they don’t act immediately.

Social Engineering

Smishing messages often employ psychological manipulation. They might create a sense of urgency, fear, curiosity, or excitement, leveraging human emotions to trick the recipient into taking the desired action.

Deceptive Links

The message includes links to websites that appear legitimate but are malicious. These websites are crafted to steal personal information or distribute malware. Clicking on these links is a crucial step in the attack.

Data Collection

If the recipient clicks on the provided links, they are often led to a fake login page that requests sensitive information, such as usernames, passwords, Social Security numbers, or credit card details. Alternatively, the website might attempt to download malware onto the device.

Exploitation

Once the attacker has acquired the target’s sensitive information or infected their device with malware, it can be used for various malicious purposes, such as identity theft, financial fraud, or further cyberattacks.

Types of Smishing Attacks

Vishing (Voice Phishing)

Vishing is a variation of Smishing that involves voice communication, often over phone calls. Attackers use phone calls to impersonate trusted entities and manipulate individuals into revealing sensitive information.

Spear-Phishing

Spear-phishing combines elements of Smishing and phishing to target specific individuals or organizations with highly personalized and convincing messages. These attacks often require extensive research on the target to craft convincing messages.

Examples of Famous Smishing Incidents

• Wells Fargo Smishing Scam: In 2020, a Smishing campaign targeting Wells Fargo customers surfaced. Attackers sent text messages, claiming to be from Wells Fargo, and asked recipients to click on a link to verify their account. Victims who fell for this scam risked exposing their banking information.
• COVID-19 Smishing Scams: During the COVID-19 pandemic, Smishing attacks surged. Attackers sent text messages offering fake COVID-19 cures, information, or financial assistance, with the goal of stealing personal and financial information from worried individuals.
• Amazon Package Delivery Scam: Smishing campaigns impersonating Amazon have tricked people into clicking on links to track non-existent package deliveries. These messages are especially prevalent during the holiday shopping season.

The Psychology Behind Smishing: Exploiting Human Behavior

Why Smishing is so effective

Smishing is highly effective due to its exploitation of human psychology. It preys on emotions, trust, and urgency, making individuals more likely to respond. People tend to trust text messages, especially those that appear to come from reputable sources. The fear of missing out, curiosity, and the desire for financial gain are powerful motivators that attackers manipulate to achieve their goals.

The emotional triggers used by attackers

Attackers exploit various emotional triggers, including:

• Fear: Creating a sense of urgency or fear in the message, such as threats of legal action or account suspension.
• Curiosity: Promising prizes, exclusive offers, or intriguing content to pique curiosity and entice recipients to click on links.
• Trust: Impersonating trusted organizations or individuals to establish a sense of trust.
• Greed: Offering financial incentives, like winning a lottery, to lure recipients into taking action.

Protecting Yourself from Smishing

Recognizing Smishing Attempts

Identifying suspicious text messages:

• Unsolicited Messages: Be cautious of messages from unknown or unexpected sources.
• Urgent Requests: Be skeptical of messages demanding immediate action or threatening consequences.
• Requests for Personal Information: Legitimate organizations won’t ask for sensitive information via text messages.
• Too Good to Be True: If an offer or prize seems too good to be true, it probably is.
• Misspellings and Poor Grammar: Many Smishing messages contain spelling errors or grammatical mistakes.
• Unusual Sender Information: Examine the sender’s details; it may be spoofed or appear slightly altered.
