Network analytics technology detected abnormal traffic patterns
MAE SOT, Tak – March 5, 2026 – True Corporation detected suspicious internet usage through its network monitoring and data analytics systems and subsequently coordinated with the Anti-Online Scam Center (ACSC) under the Central Investigation Bureau (CIB) of the Royal Thai Police and the Office of the National Broadcasting and Telecommunications Commission (NBTC). The intelligence led to a joint inspection and search operation at a suspected company site in Mae Tao subdistrict, Mae Sot district, Tak province, along the Thailand–Myanmar border, where authorities dismantled an illegal cross-border internet transmission point suspected of supporting call center scam operations targeting Thai victims.
The investigation began after True’s network surveillance system detected significant abnormal internet traffic patterns from two corporate subscribers registered at the same location. Initially, the internet usage appeared normal when the high-speed circuits were installed.
However, network utilization data between February 22–25, 2026 showed that internet traffic from the location had surged and remained continuously high 24 hours a day, with virtually no idle periods, a pattern inconsistent with typical office operations. The installation address was also situated along the Moei River, directly opposite territory in Myanmar, prompting deeper investigation in coordination with the ACSC under the CIB and the NBTC.
Further evidence emerged when investigators found that the building had no regular occupants, with only two to three individuals occasionally present. This raised further suspicion that the premises were being used as a relay point for transmitting internet connectivity across the border. Inside the building, large network equipment racks were found to have been modified, including the installation of additional network management and gateway devices that were not part of the service provider’s standard equipment.
The configuration strongly indicated that the facility had been converted into an internet relay node, receiving high-speed connectivity from Thailand and transmitting the signal across the Moei River to Myanmar.
True subsequently submitted all technical evidence to the Anti-Online Scam Center (ACSC) under the Central Investigation Bureau (CIB) and the NBTC, enabling authorities to conduct the field operation that resulted in the dismantling of the suspected cross-border internet relay linked to call center scam networks.
Pol. Lt. Col. Trin Leelanuch, Investigator at the Technology Crime Division, Central Investigation Bureau (CIB), Royal Thai Police, said, “The investigation began after abnormal internet traffic was detected at a company location in Mae Sot district near the border. Authorities closely monitored the activity and gathered evidence before obtaining a court search warrant.
The search revealed illegally installed and modified equipment used to transmit internet signals across the border to Myanmar. Officers coordinated with the service provider to immediately terminate the network circuits and seized the illegal equipment as evidence. Authorities are now pursuing the suspects for legal prosecution.”
Mr. Suteera Puengtham, Executive Director, Telecommunication Enforcement Bureau, Office of the National Broadcasting and Telecommunications Commission (NBTC), said, “Border areas, including the Thailand–Myanmar frontier, are particularly vulnerable to unauthorized cross-border internet use due to their geographic proximity. The NBTC therefore works closely with telecom operators to strictly enforce regulatory measures governing internet services and network installations along border areas. Whenever suspicious activity is detected, we cooperate immediately with operators and law enforcement agencies such as the CIB to take legal action.”
Mr. Chakkrit Urairat, Chief Regulatory and Government Relations Officer of True Corporation Plc., said, “True has continuously worked closely with the Anti-Online Scam Center under the CIB and the NBTC, particularly in monitoring and detecting abnormal internet usage in border areas. This helps prevent telecom infrastructure from being exploited by cybercriminal networks. This case demonstrates how network monitoring technology and data analytics can help identify suspicious activities and reduce risks from online crimes that harm the public.”
In addition to supporting proactive law-enforcement efforts, True has strengthened SIM card sales and registration controls, while leveraging AI and data analytics to assess risk patterns associated with phone number usage to prevent misuse.
At the same time, True provides True CyberSafe to all True and dtac subscribers free of charge. The network-level cybersecurity service can alert users to potential scam calls, warn about suspicious SMS messages, and automatically block malicious links and websites embedded in messages, without requiring customers to download any additional application.
