What exactly is smishing?
Smishing is an advanced form of cyber fraud that uses SMS messages as the main tool for extracting confidential information. It is a type of phishing directed specifically at mobile devices, in which cybercriminals send fake text messages impersonating trusted institutions. According to Proofpoint’s 2024 State of the Phish report, over 75% of organizations experienced smishing attacks in 2023.
A key element of smishing is psychological manipulation aimed at prompting the victim to take specific actions. Criminals construct messages in a way that provokes immediate response, using social engineering techniques. They most often use messages that generate fear, urgency, or excitement, which force the user to act quickly without carefully considering the situation.
Professional cybercriminals use advanced techniques such as phone number spoofing to make messages appear authentic. Statistics indicate that smishing is particularly dangerous because mobile phone users are more likely to respond quickly to text messages compared to emails.

Cybercriminals can use smishing as a method of installing malware or obtaining access credentials to company platforms. Particularly dangerous are attacks directed at employees in finance, HR, or IT departments who have access to sensitive systems.
Professional organizations must implement comprehensive protection strategies that include not only advanced technical solutions but also systematic employee training. It is key to create a cybersecurity culture that emphasizes threat awareness and a proactive approach to protecting company data.
How to educate employees about smishing threats?
Educating employees about smishing threats requires a comprehensive, multi-layered approach that combines theory with practical training scenarios. It is key to create an educational program that not only conveys knowledge but also develops critical thinking and reflexes in potential threat situations.
Professional educational strategies should include regular interactive workshops during which employees can learn about the latest smishing techniques through practical simulations. Cybersecurity experts recommend conducting controlled phishing tests that allow for assessment of employees’ real knowledge and reactions under conditions similar to real threats.
It is also extremely important to create clear, understandable procedures for dealing with suspicious messages. Employees should know who and how to report potential threats, and understand the consequences of improper handling of such messages.
What are effective methods of protection against smishing?
Effective protection against smishing requires a multi-layered approach that combines advanced technological solutions with employee education and awareness. It is key to implement a comprehensive strategy that includes both prevention and response mechanisms to potential threats.
