Understanding Smishing: A definition

How does smishing work? It’s a form of cybercrime, also known as SMS phishing, that exploits deceptive text messages to deceive individuals into revealing sensitive personal or financial information or installing malicious software on their devices.

The primary aim of smishing is to either trick victims or individuals into providing confidential data that can be used for identity theft, financial theft, or other illicit activities.

With the widespread use of short message service as a form of communication, smishing has become an increasingly prevalent cybersecurity threat.

The mechanics of smishing attacks

At the heart of smishing attacks (which is a form of phishing), lie deceptive text messages and links to malicious websites. These messages often appear to be from legitimate sources, such as financial institutions, government agencies, or well-known companies, that are carefully crafted to deceive victims into providing sensitive information or clicking on malicious links.

The consequences of falling for a smishing attack can be severe, potentially leading to identity theft, financial fraud, or other malicious activities. To combat smishing, it is important to understand its mechanics, be aware of the warning signs, and adopt robust security measures to protect against this ever-evolving threat.

Deceptive text messages

Deceptive text messages(smishing), are fraudulent or malicious text messages designed to manipulate and exploit unsuspecting individuals. Scammers use these messages to extract sensitive personal information, such as passwords, credit card numbers, or bank account information, from victims.

These messages often appear as legitimate communications from trusted sources but contain language that is urgent or demands immediate action.

To protect against smishing attacks, it is crucial to be mindful of the warning signs of a smishing message and never click on links or divulge personal information in response to a suspicious text message. Keeping devices and software up-to-date can also help defend against smishing attacks.

Malicious links and websites

In addition to deceptive text messages, smishing attacks often rely on malicious links and websites to ensnare victims. These links and websites are designed to deceive users, persuading them to divulge personal information or download malware on to their devices.

Clicking on a malicious link can lead to a fraudulent website where the victim is prompted to provide their banking information, enabling the attacker to gain access to the victim’s bank account details and steal their funds.

To minimise the risk of falling prey to such attacks, it is essential to exercise caution and avoid clicking on dubious links or visiting unfamiliar websites. If you suspect that you’ve clicked on a malicious link or visited a malicious website, contact your bank or financial institution immediately and change your passwords.

Identifying and recognising Smishing messages

Recognising smishing messages can be challenging, but there are certain telltale signs to look out for. Verifying the sender’s phone number, noting any grammatical errors, and identifying visual inconsistencies in the message can help you distinguish genuine communications from smishing attempts.

Smishing messages, also known as smishing text messages, may appear to be from a credible source, such as a bank or other financial institution, and may contain language that is pressing or requests for immediate action. Therefore, it is essential to be watchful and prudent when receiving text message, particularly from senders that are unfamiliar or suspicious.

Common types of Smishing scams

Smishing scams come in various forms and can target individuals in different ways. Some common types of smishing scams include:

  • Impersonation scams

  • Tech support scams

  • Account suspension scams

  • Missed delivery scams

  • Prize/lottery scams

  • Charity scams

  • Malware link scams

Impersonation scams involve attackers posing as well-known organisations or individuals, such as banks, government agencies, or reputable companies, to request personal information in order to gain the trust of their victims.

Tech support scams, on the other hand, involve attackers pretending to be representatives from tech companies, claiming that the victim’s device or account has been compromised and that they require sensitive data to resolve the issue.

Messages claiming that an account has been suspended are part of account suspension scams. These scam messages prompt the victim to provide sensitive information to verify their identity. Missed delivery scams involve perpetrators sending communications that in messages claim that the recipient has not received a package delivery, and they are required to supply personal information or a payment to rearrange the delivery.

Prize or lottery scams falsely inform victims that they have won a prize or lottery, and require them to provide personal details or make a payment to claim the purported winnings. Charity scams involve unscrupulous individuals falsely representing themselves as legitimate charitable organisations and soliciting donations, often after a major event or during the holiday season.

Malware link scams involve messages containing a link that, when clicked, installs malicious software on the victim’s device, allowing the attacker to access confidential information or gain control over the device.

Preventing and protecting against smishing attacks

To protect against smishing attacks, it is vital to:

  • Remain vigilant of unsolicited messages

  • Avoid clicking on links in unexpected or unsolicited text messages

  • Confirm the sender’s identity through reliable communication channels

  • Deploy security software, such as McAfee Mobile Security, to help safeguard against smishing attacks.

In addition to these measures, it is important to:

  • Increase awareness about smishing attacks

  • Educate ourselves and others about the warning signs and best practices for defence

  • Employ two-factor authentication for online accounts to add an extra layer of security, making it more difficult for attackers to gain access to your personal information.

If you suspect a smishing attempt, do not respond to the message. Report it to your mobile carrier by forwarding the message to 7726 (SPAM).

7726 is a number that most mobile customers using UK networks can text to report unwanted SMS messages or phone calls on a mobile. The number ‘7726’ was chosen because it spells ‘SPAM’ on an alphanumeric phone keypad – that’s a handy way of remembering it.

Taking these proactive steps can significantly reduce the likelihood of falling victim to smishing attacks and help protect our sensitive information from cybercriminals.

  1. Do not click on any links in the suspicious message.

  2. Verify the message source by contacting the supposed sender through reliable channels.

  3. Report the smishing attempt to your mobile carrier by forwarding the message to 7726 (SPAM).

After reporting the smishing attempt, take the necessary steps to secure your personal information and other personal data. Here’s what you should do:

  1. Change your passwords.

  2. Monitor your accounts for suspicious activity.

  3. Contact your bank or financial institution if you believe your financial information has been compromised.

By acting swiftly and diligently, you can minimise the potential damage caused by a smishing attack.
