What Is a Smishing Attack and How to Prevent One?

Smashing attacks involve harmful text messages, leading individuals and businesses to lose money and data.

Cyber attackers exploit users’ inclination to trust text messages, using fear or excitement to manipulate them and compromise data in the blink of an eye without you even realizing it.

Picture this – you’re scrolling through your messages and suddenly receive a text claiming you’ve won a grand prize. It seems too good to be true, yet oddly convincing. 

You are tempted to click on the link given in that text. Once done, next comes the shock of finding your bank account drained or your identity stolen, all from a seemingly harmless text. 

Welcome to the world of smishing attacks – a growing threat is catching even the savviest individuals off guard. 

In fact, in the first 6 months of 2021 alone, smishing attacks have seen a jaw-dropping 700% increase worldwide.

Thus, the urgency to defend yourself against these manipulative tactics has never been more pressing.

In this article, I’ll delve deeper into what smishing attacks are, their types, and how you can protect yourself from them.

Let’s get started!

What Is Smishing?

Smishing, short for “SMS phishing,” is a cyber threat that preys on your trust, fear, excitement, and bank account through harmful text messages that appear legitimate. But in reality, they are not. 

These texts tempt people to click on harmful links or share confidential information.

The goal behind smishing attacks is to steal your personal info, money, or even your identity for fraudulent activities. 

In this type of cyberattack, the victim receives a text indicating that they have won some kind of prize or they might need to update their account information urgently. It might include a malicious link. The text will prompt you to click on that link to perform the next step, like availing the prize or making changes to your account. 

So beware, these are tricks that cyber criminals employ to fool people and carry out attacks.

In 2021 and 2022, a staggering 76% of organizations globally faced some kind of smishing attack, as reported by Statista. This unsettling truth underscores the widespread nature of this threat.

Staying safe begins with being careful. Don’t click on links or give out your personal information unless you’re sure the message is genuine. Look at who sent the message, and watch out for mistakes or strange requests. Remember, real companies like banks won’t ask for your passwords or sensitive details in text messages.

Increased Mobile Usage and Smishing: Is It Concerning?

As mobile devices have become an integral part of everyone’s life, the likelihood of smishing attacks taking place is more. This is undoubtedly highly concerning for everyone, whether you are an individual or a business. 

With the incre­ase in mobile usage, cybe­rcriminals have discovered a lucrative­ opportunity to exploit information and money. In 2021, about 87.8 billion unwanted spam texts were sent to phone numbers in the US alone. This caused people to lose more than $10 billion in total.

Today, phones have become essential tools for tasks like banking and socializing. However, this ongoing reliance also exposes people to manipulative strategies that cybercriminals employ. These­ attackers se­nd convincing messages that tempt people into taking impulsive­ actions without giving a second thought.

The conse­quences of smishing can be shocking, re­sulting in drained bank accounts and stolen data and identitie­s. This is why it is crucial to understand that smishing is not just an annoyance but also a serious thre­at to your financial security and personal privacy.

It’s understandable that you can’t stop using your phone since it’s essential in both your personal and professional lives. But you can stay informed and cautious. By understanding the­ risks and remaining vigilant, you can safeguard yourself against the­ deceptive clutche­s of smishing attacks.

Types of Smishing Attacks

Educating yourse­lf about the various types of smishing attacks equips you with the­ knowledge to recognize­ and avoid falling prey to these malicious tactics. 

So, let’s explore the different types of smishing attacks.

Phishing Smishing

This traditional form of smishing entices you to click on harmful links that direct you to fake websites. These sites may appear identical to legitimate ones, like your bank’s site. Here, you will be prompted to enter your sensitive details, which the attacker then captures and uses the data to deploy an attack.

Vishing Smishing

This is a more personalized approach. Scammers use voice calls alongside text messages. They might leave voicemails or send SMSes warning you about compromised accounts or fraudulent activities, asking you to call a number or click on a link. Once you do, they extract personal information from you.

Prize Smishing

The thought of suddenly winning something can make anyone excited. Cybercriminals exploit this by sending messages like congratulating you on winning a prize. But you actually have not entered any such contest. 

In this type of smishing attack, the attacker will ask for your personal details or a ‘small fee’ to claim the prize. Next, they are nowhere to be found, as they will eventually run off with your money and data.

Financial Smishing

These messages often mimic legitimate financial institutions, claiming suspicious activities on your account that need your immediate attention. Fearful of this, you may click the provided link and unknowingly provide access to your account. 

Urgent Action Smishing

Capitalizing on a sense of urgency, these messages warn of a time-sensitive situation that requires immediate action. Whether updating your account, confirming a purchase, or verifying a transaction, these messages aim to make you act quickly without thinking. 

App Smishing

Attackers might send you a text claiming to be from a popular app store, prompting you to download an update or a new app. However, the link leads to a fake site, downloading malware onto your device.

Friendship Smishing

This particularly deceptive technique involves cybercriminals posing as friends or family members. They might ask for financial help or sensitive information from you, exploiting your trust in your relationships.

Travel Smishing

Capitalizing on wanderlust, scammers might send texts about exclusive travel deals or booking confirmations for trips you never planned. Clicking the links can lead to data theft or malware installation.

Charity Smishing

Cybercriminals prey on your goodwill by sending messages from fake charity organizations during a disaster or need. They request donations, but the money never goes to those in need.

Security Alert Smishing

These messages exploit concerns about security breaches, stating that your account has been compromised. They urge you to take immediate action or share sensitive information, like OTPs, with the attackers. And when you do that, they empty your bank accounts or gain unauthorized access to carry out a full-blown attack.

Real-Life Examples of Smishing Attacks and Their Consequences

Let’s de­lve into real-life examples of these attacks and their dreadful consequences.

#1. The “Bank Account Compromise”

Imagine re­ceiving a text message­ from a number that seems to be your bank informing you about unauthorized activity on your account. The­ message urgently re­quests you to click a link to verify your details.  

An unsuspecting victim clicks on this link and enters their personal information. Soon, the attackers gain access to their bank accounts. The result was – emptied bank account and financial turmoil.

Case: Deakin University Smishing Attack is a high-profile smishing incident at Australia’s Deakin University, putting nearly 47,000 current and past students’ identities and data at risk. The breach occurred after a single staff member’s credentials were compromised, allowing an unauthorized individual to access a bulk-SMS messaging service used by the university to communicate with students.

#2. The “Free Gift Card” Scam

Victims receive messages saying they’ve won a gift card or prize. All they need to do is provide their personal details or pay a small shipping fee in order to receive the prize or gift card. Once the recipient gives them the information or pays the fee, the attacker disappears, scamming the victim and compromising the personal information.

Case: Government agency impersonation is a real-life example of a gift card scam. Individuals received phone calls from scammers claiming to be from a government agency, such as the Social Security Administration.

This scam saw a significant rise in 2021, with nearly 40,000 consumers reporting a loss of $148 million in the first nine months of the year, as per the Federal Trade Commission (FTC). The median amount lost to such scams in 2018 was $700, which increased to $1,000 in 2021. Older individuals, especially those aged 50 and above, were found to be more susceptible to these scams.

#3. The “Fake App Update” Trick

You may re­ceive a text me­ssage urging you to immediately update­ a popular app. Be cautious if that happens.

The­ link provided in the text le­ads to a fake app infecte­d with malware. If you install this malicious app, your personal information, including banking details, could be­ stolen. Furthermore, your de­vice might be compromised, allowing hacke­rs to control it. As a result, your device might be compromised, and your data might get stolen.

Case: In a report by ZDNet, Android Trojan Malware Attack was discovered that posed as a system update. Users received a message urging them to update their system. However, upon downloading and installing this “update,” it acted as a remote access trojan, giving attackers full control over the victim’s device.

This allowed them to capture a wide range of data, including messages, photos, and even GPS data. The malware was sophisticated and could even record phone calls, making it one of the most invasive Android malware strains.

#4. The “IRS” Threat

People have received a text from the Internal Revenue Service (IRS) insisting on instant payment for overdue taxes or a warning of legal consequences. Fearing this, victims comply by sharing their financial information or making the requested payment. The result – is financial loss and exposed identity.

Case: In September 2022, the Internal Revenue Service (IRS) warned about a surge in IRS Text Scams. The scam texts often lured victims with claims of fake COVID relief, tax credits, or assistance in setting up an IRS online account.

One notable incident involved a taxpayer who received a message claiming they owed back taxes and needed to click on a provided link to clear their dues. Upon clicking, they were redirected to a phishing site that attempted to harvest their personal and banking details.

#5. The “Travel Confirmation” Scam

Victims have got a text claiming to be a travel confirmation for a trip they didn’t book. Being curious, they click on the link to cancel the booking, unknowingly downloading malware onto their device. 

The malware can steal personal information, login credentials and even record keystrokes. This has compromised privacy and caused potential financial losses.

Case: Mevonnie Ferguson, a resident of Kent in the UK, is reported to be a victim of the Real Flight Reservation Scam. She was deceived by a scammer claiming to represent a travel agency named Infinity Global Travel. She was sold what appeared to be a legitimate British Airways ticket from London to Kingston, Jamaica.

After checking the reservation on BA’s website using the confirmation number, it seemed valid. However, about two weeks post-purchase and just days before her departure, the reservation vanished from BA’s site. Upon contacting the airline, she discovered there was no flight booked in her name. The scammer had exploited the difference between a “confirmed” and a “ticketed” reservation, making it appear to be a valid booking when, in reality, it was just a temporary hold.

#6. The “Romance Scam”

In some scenarios, cybercriminals build emotional connections with victims over texts, pretending to be interested in a romantic relationship. Once they successfully establish trust, they manipulate victims into sharing personal and financial information. This can cause heartache, betrayal, and financial ruin.

Case: A cybercriminal impersonated Gen. Paul Nakasone, the director of the National Security Agency and head of U.S. Cyber Command, in an attempt to lure women into a romance scam. The scammer initiated false email conversations with women on social media platforms, using the general’s identity. In one instance, the imposter claimed to be stationed in Syria and inundated a woman with religious messages, urging her to communicate via Google Hangouts.

Preventive Measures Against Smishing Attacks

The consequences of smishing attacks are more than just financial – they can shatter trust, compromise privacy, and leave victims emotionally scarred.

Let’s delve into some effective ways to prevent smishing attacks from happening in the first place.

#1. Awareness and Training 

In today’s interconne­cted digital landscape, it is esse­ntial for your organization to arm its workforce with knowledge in orde­r to protect sensitive information. 

According to a re­port from ID Agent, businesses face­ an average cost of $15,000 from smishing attacks. The financial impact highlights the­ urgent need to e­ducate your team.

To fortify your defe­nses against stealthy cyber thre­ats, prioritize comprehensive­ training on smishing and spread awareness throughout the organization. This will help everyone to be pre­pared for these malicious attacks and respond to them intelligently. 

Furthermore, attending re­gular workshops that provide insights into smishing attacks enables your e­mployees to distinguish betwee­n legitimate message­s and potential scams. By equipping them with the­ ability to identify suspicious links, urgent demands, or une­xpected reque­sts, your staff becomes an intimidating barrie­r against these malicious attempts.

#2. Verifying the Sender’s Identity

By confirming the sender’s identity, you significantly decrease the likelihood of becoming a target of smishing attacks.

#3. Being Cautious with Text Messages

Extending your cautious approach from emails to text messages is essential in safeguarding your digital assets. Cybercriminals frequently capitalize on the convenience and familiarity of text messages to manipulate their targets.

#5. Utilize Multi-Factor Authentication

To fortify your digital data, implementing multi-factor authentication (MFA) is a powerful strategy. In addition to password-based security, MFA requires an extra laye­r of verification. This typically involves a code se­nt to another device or a finge­rprint scan. 

Incorporating this intricate security framework, you can increase the­ complexity of potential attacke­rs attempting to breach your accounts. It will act as a prote­ctive shield to safe­guard you from deceptive attempts.

#6. Use Strong Passwords

Your phone, computers, and other devices hold a lot of your private information. An easy yet effective way to keep the data safe is using a strong password for each device.

Create a strong password that combines letters, numbers, symbols, and uppercase and lowercase letters. This makes it harder for hackers to guess your password. This helps thwart potential smishing attackers and bolsters your overall digital security.

#7. Report Smishing Attacks
