Smishing, also known as SMS phishing, is a type of phishing assault that takes place using a text message.
Victims are duped into providing critical information to a disguised attacker in this variation of phishing. Malware or fraudulent websites might help in SMS phishing. It happens on a variety of mobile text messaging systems, as well as non-SMS channels such as data-based mobile messaging applications.
What is smishing?
Smishing is a phrase that combines “SMS” (short messaging services, sometimes known as texting) and “phishing,” as its meaning indicates. Smishing is classified as a sort of social engineering assault that depends on human trust rather than technological vulnerabilities to succeed. When hackers “phish,” they send bogus emails in the hopes of duping the receiver into clicking on a dangerous link. Instead of email, smishing uses text messages.
These hackers are attempting to steal your personal information, which they will subsequently use to perpetrate fraud or other cybercrimes. This generally entails stealing money – usually your own, but occasionally also your company’s.
To steal this information, cybercriminals frequently choose one of two methods:
Malware: The smishing URL link might deceive you into installing malware, or harmful software, onto your phone. This SMS spyware might impersonate a legitimate app and fool you into putting in sensitive information and transmitting it to crooks.
Malicious website: The URL in the smishing message might take you to a false website that asks for sensitive personal information. Cybercriminals employ custom-made harmful websites that are meant to seem like legitimate websites, making it simpler for them to steal your personal information.
Smishing SMS messages frequently impersonate your bank, requesting personal or financial information such as your account or ATM number. Giving up the information is akin to handing over the keys to your bank account.
Smishing is growing a corporate and consumer danger as more individuals use their smartphones for work (a trend known as BYOD, or “bring your own device”). As a result, it’s no wonder that smishing has become the most common type of harmful text message.
Cybercrime targeting mobile devices is on the rise, as is mobile device usage. Aside from the fact that texting is the most prevalent usage of cell phones, there are a few additional elements that make this an especially sneaky security issue. Let’s take a look at how smishing attacks operate first.
What is Smishing and how does it work?
Any SMS phishing assault relies heavily on deception and fraud. Because the attacker develops a persona that you may trust, you are more inclined to follow their demands.
Smishing attackers can affect a victim’s decision-making via social engineering techniques. Three reasons are at the root of this deception:
1. Trust: By impersonating real people and businesses, fraudsters reduce their victims’ suspicion. As a more intimate communication channel, SMS messages reduce a person’s natural defenses against attacks.
2. Context: An attacker can create an effective disguise by using a circumstance that is relevant to the victim. The message has a personalized feel to it, which helps it overcome any suspicions of spam.
3. Emotion: Attackers can overpower a target’s critical thinking and compel them to respond quickly by inflaming their emotions.
How does Smishing spread?
Smishing attacks may be distributed using both standard text message and non-SMS messaging apps, as previously noted. Due to their deceitful nature, SMS phishing attempts typically proliferate unreported and unannounced.
Smishing deception is aided by consumers’ erroneous faith in the security of text messages.
To begin with, most individuals are aware of the dangers of email fraud. You’ve undoubtedly learned to be wary of emails that start with, “Hello—check out this link.” The absence of a genuine personal note is usually a major warning signal in email spam schemes.
People are less cautious while they are on their phones. Many people believe that their cell phones are safer than their laptops. However, smartphone security has its limits, and it cannot always prevent smishing directly.
Whatever tactics are employed, these scams rely on little more than your confidence and a mistake in judgment to succeed. As a result, smishing may infect any mobile device that can send text messages.
While Android smartphones are the most popular and are a prime target for malware text messages, iOS devices are also vulnerable. Although Apple’s iOS mobile technology has a high-security reputation, no mobile operating system can protect you from phishing-style assaults on its own. Users, regardless of platform, might be especially vulnerable if they have a false feeling of security.
Another danger factor is that you use your smartphone while on the road, frequently when distracted or in a hurry. When you receive a message asking for bank information or to redeem a coupon, you’re more likely to let your guard down and answer without thinking.
Types of Smishing attacks
The mechanisms used in each smishing attack are identical, although the presentation varies greatly. To keep these SMS attacks interesting, attackers might utilize several identities and locations.
Unfortunately, because of the constant reinvention of these attacks, compiling a complete list of smishing varieties is practically hard. We can provide traits to assist you to recognize a smishing assault before you become a victim using a few well-known scam premises.
The following are some of the most typical premises of smishing attacks:
COVID-19 smishing schemes are modeled on actual COVID-19 rehabilitation programs developed by the government, healthcare providers, and financial institutions.
Attackers have utilized these techniques to prey on victims’ anxieties about their health and finances to perpetrate fraud. Contact tracing that requests sensitive information is one of the warning flags (social security number, credit card number, etc.)
Financial assistance is based on taxes, such as stimulus cheques.
Updates on public health safety.
Requests for the United States Census to be completed.
Smishing on Financial Services
Smishing attacks on financial services are disguised as notifications from financial organizations. Almost everyone utilizes banking and credit card services, rendering them vulnerable to communications from both general and institution-specific sources. In this category, loans and investments are also frequent.
An attacker disguises himself as a bank or other financial institution to conduct financial fraud. An urgent request to access your account, being requested to verify suspicious account activity and other features of a financial services smishing scam may be included.
Smishing of Gifts
The promise of free services or items, usually from a respected merchant or another firm, is referred to as gift smishing. Giveaway competitions, shopping incentives, and a variety of other freebies are examples. When an attacker uses the concept of “free” to increase your enthusiasm, this acts as a logic override to persuade you to respond quickly. Limited-time offers or exclusive selections for a gift card might be signs of an assault.
Smishing on an invoice or an order confirmation
A fraudulent confirmation of a recent purchase or billing invoice for a service is known as confirmation smishing. To exploit your interest or drive immediate action to generate fear of unwanted charges, a link may be supplied for a follow-up. Strings of order, confirmation texts, or the lack of a business name might be evidence of this fraud.
Smishing in Customer Service
Smishing attackers impersonate a trustworthy company’s assistance professional to assist you in resolving a problem. In this hypothesis, high-use tech and e-commerce enterprises such as Apple, Google, and Amazon are ideal disguises for attackers.
An attacker will usually pretend that there is a problem with your account and provide you with instructions on how to fix it. The request may be as easy as utilizing a bogus login page, or it could be as complicated as being asked to supply an actual account recovery number to change your password. A problem with invoicing, account access, strange behavior, or addressing your recent customer complaint are all signs of a support-based smishing scam.
Examples of smishing
Smishing attacks have been reported across the world because SMS is accessible to practically everyone with a mobile phone. Here are some instances of smishing attacks to be careful of.
Apple iPhone 12 Early Access Scam — Order Confirmation & Gift Smishing
A smishing effort appeared in September 2020, luring individuals into supplying credit card information in exchange for a free iPhone 12.
The strategy is based on the order confirmation premise, in which a text message says that a product delivery was delivered to the wrong address. The in-text URL link redirects victims to a phishing site impersonating an Apple chatbot. The gadget walks the victim through the steps of claiming their free iPhone 12 as part of an early access trial program. but it will eventually ask for credit card information to cover a tiny shipping price.
Scams using the USPS and FedEx – Order Confirmation and Gift Smishing
Reports of a fake USPS and FedEx package delivery SMS scam started spreading in September 2020. This smishing attack might try to steal your credit card information or your account credentials for multiple services.
The communications began with a claim of missing or wrong package delivery, followed by a link to a website phishing tool masquerading as a FedEx or USPS giveaway survey. While the motive behind these phishing sites varies, several have been recognized as seeking to collect account logins for services such as Google.
COVID-19 Smishing — Mandatory Online COVID-19 Test Scam
The Better Business Bureau reported an increase in instances of U.S. government impersonators sending text messages requesting that individuals take a necessary COVID-19 test via a connected website in April 2020.
Because there is no online exam for COVID-19, many people have immediately recognized this hoax. The concept of these smishing attacks, on the other hand, may readily develop, as playing on public concerns of a pandemic is a successful means of victimizing the public.
How to prevent Smishing
The good news is that assaults’ possible consequences are simple to guard against. By doing nothing, you can keep yourself secure. In other words, the attacks may only harm you if you accept the bait.
However, keep in mind that many shops and organizations use text messaging to communicate with you. Although not all signals should be disregarded, you should always behave safely.
There are a few things to remember to defend oneself from these attacks.
Don’t say anything. Even suggestions for responding, such as texting “STOP” to unsubscribe, may be used to track down current phone numbers. Attackers rely on your interest or fear about the issue, but you have the option of refusing to engage.
If you have any doubts, contact your bank or merchant immediately. Text messages are not used by legitimate organizations to seek account changes or login information. Any urgent alerts may also be confirmed immediately on your online accounts or by calling authorized phone support.
Use no links or contact information in your message. Use caution when sending links or contact information in communications that make you feel uneasy. When possible, go straight to formal communication channels.
Make sure the phone number is correct. Email-to-text services can be identified by odd-looking phone numbers, such as 4-digit ones. This is just one of the numerous ways a fraudster might hide their genuine phone number.
Keep credit card numbers off your phone if at all possible. The greatest method to avoid having financial information stolen from a digital wallet is to never put it there in the first place.
Multi-factor authentication should be used (MFA). If the account being hacked requires a second “key” for verification, a revealed password may still be worthless to a smishing attacker. Two-factor authentication (2FA), which frequently employs a text message verification code, is the most used MFA option. Stronger options include employing a specialized verification app (such as Google Authenticator).
Texting a password or account recovery code is never a good idea. In the wrong hands, both passwords and text message two-factor authentication (2FA) recovery codes might jeopardize your account. This information should never be shared with anybody and should only be used on official websites.
Install an anti-malware program. Malicious applications, as well as SMS phishing links, may be protected with products like Kaspersky Internet Security for Android.
All SMS phishing attempts should be reported to the appropriate authorities.
Remember that smishing, like email phishing, is a deception-based crime that relies on duping the victim into clicking a link or submitting information. The most basic defense against these attacks is to do nothing. A harmful SMS can’t accomplish anything if you don’t answer.
What should you do if you’re the victim of smishing?
Smishing attacks are sophisticated, and you may have previously been a victim, so you’ll need to have a strategy in place to recover.
Take the following steps to mitigate the consequences of a successful smishing attempt:
Notify any institutions that may be able to help with the potential assault.
Freeze your credit to protect yourself against identity theft in the future.
If at all feasible, change all passwords and account PINs.
Keep an eye on your cash, credit, and internet accounts for unusual login locations and other actions. Each of these actions has a significant amount of weight regarding protecting yourself following a smishing assault. Reporting an attack, on the other hand, not only aids your recovery but also prevents others from becoming victims.
