In our interconnected world, cyber threats are ever-evolving, and one deceptive tactic that has gained prominence is smishing.

This article aims to shed light on smishing, equipping readers with the knowledge to identify such attacks and fortify their defenses against this increasingly sophisticated form of cybercrime.

Understanding Smishing:

Smishing is a form of social engineering in which attackers use text messages to manipulate their targets into divulging sensitive information such as; personal information, passwords, 2fa authentication, or performing actions that compromise their security. In order to create a false sense of legitimacy, these messages often impersonate trusted entities such as banks, government agencies or popular online platforms.

Recognizing Smishing Attacks:

  1. Unusual Sender IDs: Be wary of messages from unfamiliar or irregular sender IDs. Legitimate organizations typically use recognizable names or shortcodes. If the sender information seems off, exercise caution.
  2. Spelling and Grammar Errors: Smishing messages often contain spelling mistakes or grammatical errors. Genuine organizations maintain a professional standard in their communication. If the message seems hastily written or contains language inconsistencies, it could be a red flag.
  3. Unexpected Links: Avoid clicking on links in unsolicited messages. Check the URL by hovering over it to ensure it matches the claimed sender’s official website. Legitimate organizations seldom send clickable links via SMS.
  4. Urgent or Threatening Language: Smishing messages often create a sense of urgency or threat to prompt immediate action. Be skeptical of messages claiming imminent account suspension, legal action, or other dire consequences. Verify the legitimacy independently before taking any action.
  5. Requests for Personal Information: Legitimate entities rarely request sensitive information through text messages. Be suspicious of messages asking for personal details, passwords, or financial information. Verify such requests through official channels.

Protecting Yourself from Smishing:

  1. Stay Informed: Regularly educate yourself about the latest smishing tactics and smishing scams.  Also ensure to have a robust employee cybersecurity training program in place. Awareness is your first line of defense, enabling you to recognize potential threats and respond accordingly.
  2. Verify Messages Independently: If you receive a suspicious message, verify its authenticity by independent verification. Instead of responding directly, use official contact information from the organisation’s website to verify the authenticity of the message.
  3. Enable Two-Factor Authentication (2FA): Enable 2FA to add additional layers of security to your accounts, whenever possible: 2FA is an additional layer of protection from unauthorised access, in case your password has been lost, hacked or stolen.
  4. Use Security Apps: Evaluate installing reputable security apps designed to detect and block smishing attempts. Although there is no alternative to education and vigilance, these applications can offer an extra layer of protection against malicious messages.
  5. Report Suspicious Messages: Report smishing attempts to your cell phone provider and local authorities to help in tracking and preventing the spread of such scams, contributing to the collective effort to combat cybercrime.
  6. Avoid the temptation of Smishing: Scammers are becoming more sophisticated and are very good at playing on your emotions.  If something sounds too good to be true, stop and consider if it’s worth the risk.


In the digital age, safeguarding against smishing requires a combination of vigilance, awareness, and proactive measures. By understanding the tactics employed by smishers and implementing the suggested protective measures, individuals can significantly reduce their vulnerability to these deceptive attacks. Remember, staying one step ahead in the evolving landscape of cyber threats is the key to maintaining a secure digital environment.
