What is Smishing and How to Prevent It?
Smishing, a prevalent form of social engineering, utilizes text messaging to trick individuals into revealing sensitive information. These attacks pose significant risks to both personal security and privacy, with the potential for severe repercussions. Prompt recognition of smishing tactics is essential for prevention and response. Staying alert and implementing strong security measures are critical in reducing vulnerability to these threats. Individuals and organizations can fortify their defense against these invasive attacks by understanding smishing and engaging in proactive defense strategies.
Smishing text messages often masquerade as legitimate entities, such as banks, asking for personal and financial information such as your account and ATM number. Succumbing to these deceptive plots grants malicious actors unfettered access to financial resources. As the use of personal smartphones for both work and personal usage grows under the BYOD framework, smishing becomes a formidable challenge for businesses and consumers.
Let us understand smishing in detail.
What is a Smishing Attack?
Smishing or Short Message Services (SMS) phishing can be defined as a sophisticated cyber threat carried out through SMS or text messages. Some experts believe it is an attack that leverages SMS to exploit victims. It typically refers to exploiting traditional mobile messaging systems. This insidious tactic relies not solely on traditional platforms but also uses social media, attachments, and other communication mediums to scam people.
Smishing attacks aim to exploit vulnerabilities to gain access to passwords, photos, and other critical data. These attacks target billions of smartphone users worldwide. In 2021, the United States reported 400,000 fraud complaints related to unwanted messages, suspicious links, and smishing attacks.
How Does a Smishing Attack Work?
Smishing is a widespread form of cyber threat akin to traditional phishing. It leverages SMS and malicious links instead of emails and phone calls. Smishing tricks people into divulging sensitive details such as bank accounts or personal information. This method of exploiting user trust through text-based communications targets mobile devices to gain access to financial information and other critical data.
Scammers favour smishing for various compelling reasons. Research indicates that people are more convinced to click links within text messages, with a click rate between 8.9% and 14.5%. On the other hand, the success rate of email campaigns is comparatively low, hovering around 2%. Moreover, smishing perpetrators utilize advanced tactics such as spoofing through disposable phones or software to obscure text’s origin and cloak their identities, making it difficult to trace and mitigate such threats.
Additionally, mobile devices cannot identify malicious links in the same manner as desktops. Desktop users can easily hover over a link to verify its legitimacy. This absence, combined with the nature of legitimate SMS communication from financial institutions, signifies the effectiveness of smishing tactics.
How to Prevent Smishing Attacks?
Smishing presents vital organizational risks, as many people use personal devices such as smartphones for work. Preventing smishing is one of the best ways to safeguard business and personal information. If you take time to identify these attacks, you can protect yourself against them. There are a few crucial steps you should take care to mitigate the risks of these scams:
Do Not Respond
Avoid responding to suspicious texts, even if they ask you to stop or take other action, like unsubscribing. Responding to these scam links can confirm your phone number and lead to more targeted scams.
Slow Down Urgency
Approach urgent messages with skepticism, particularly those asking for immediate action. Urgent account offers and limited-time offers should be treated with vigilance rather than immediate action. Take time to verify the legitimacy of such messages.
Direct Verification
When in doubt, establish direct communication with your service provider to verify the legitimacy of the text. Legitimate institutions never ask for your credential information through SMS or texting. Moreover, you can verify account updates and critical notices on the verified portals or by directly calling helplines.
Avoid using Links and Contact Information
Be cautious and refrain from clicking on any links or messages that seem suspicious. Instead, manually type in the official website URLs or contact numbers to confirm their legitimacy and ensure your online security.
Verify the Phone Numbers
Verify the unusual numbers, especially those with few digits, which could indicate the use of an email-to-text sender employed by attacks to obscure their identity. Verify the legitimacy of those numbers through additional means before taking any action.
Conclusion
Smishing tactics are more appealing than any other social engineering tactics, as users are more likely to respond to texts. Overall, smishing poses a greater threat to both organizations and individuals. While following these prevention measures, we can safeguard ourselves to some extent. However, it is crucial to remember that no security measures are entirely foolproof. To protect ourselves against threats, we can stay vigilant and careful whenever someone asks for sensitive details. By checking all these measures, we can save ourselves and our business from smishing attacks.
