cybercrime has become increasingly sophisticated, with criminal groups continuously adapting their techniques to exploit vulnerabilities across the globe. One such group, known as the “Smishing Triad,” has been active since 2023 and has rapidly expanded its operations to target both organizations and individuals in over 121 countries. This blog post delves into the operations of this sophisticated Chinese eCrime group, examines their latest tactics, and provides guidance on how to protect yourself and your organization from similar threats.

The Smishing Triad has shifted its focus from traditional phishing techniques to more refined SMS phishing, commonly known as smishing. By using fraudulent text messages that mimic legitimate communications from postal services, government agencies, and even financial institutions, the group creates a sense of urgency that compels victims to click on malicious links. Over time, the group has evolved from targeting package delivery and government service lures to more insidious methods of stealing banking credentials.

The Rise of Smishing: How Chinese eCrime Hackers doing it

What Is Smishing?

Smishing is a form of phishing that uses SMS text messages to lure victims into divulging sensitive information or clicking on harmful links. Unlike traditional email phishing, smishing takes advantage of the trust people have in receiving text messages, often from sources they recognize or expect to hear from. Criminals craft messages that alert recipients to urgent issues, such as problems with a package delivery or unpaid tolls, thereby increasing the likelihood that the victim will act impulsively without verifying the authenticity of the message.

The Mechanism Behind the Attacks

The Smishing Triad employs a systematic approach to carry out their attacks. Their method involves sending out mass SMS messages that contain links to websites that have been designed to mimic legitimate portals. When users click on these links, they are redirected to convincing replicas of well-known websites, often complete with secure-looking interfaces and real-time updates that reinforce the illusion of legitimacy.

These websites are part of a vast network of malicious domains. Researchers have estimated that on any given day, there could be tens of thousands of these domains in operation. The sheer scale of this network is designed to evade detection and blocking by cybersecurity firms and regulatory authorities.

Rapid Domain Rotation

One of the most challenging aspects of combating the Smishing Triad is their rapid domain rotation strategy. It is estimated that the group maintains approximately 25,000 domains online over any given 8-day period. This high turnover rate allows them to bypass many traditional cybersecurity measures. Even if one domain is taken down or blacklisted, another is quickly put in its place, ensuring that the phishing campaign continues uninterrupted.

Shifting Targets: From Delivery and Government Services to Banking Credentials

Initially, the group focused on exploiting the vulnerabilities of individuals by targeting them with messages related to package delivery and government services. However, in a concerning development, the group has recently pivoted to stealing banking credentials. The stakes in this new focus are considerably higher, as compromising financial data can lead to substantial financial losses for both individuals and institutions.
