MAE SOT – True Corporation tracked unusual internet traffic and shared leads with Thailand’s online fraud suppression network. As a result, cyber police and the NBTC raided a suspected site in Mae Sot, Tak, believed to be sending internet signals across the Moei River into Myanmar.
On March 5, 2026, a team led by Cyber Police officers from the Technology Crime Suppression Division, NBTC telecom regulators, and True technical staff entered a suspected company location at a border cargo pier in Mae Tao subdistrict, Mae Sot district.
Officers presented a court warrant and then split up to inspect the office area, nearby grounds, and the pier, focusing on internet lines and related equipment.
Inside the premises, officials found an air-conditioned room set up like a network control center. The room contained six operating bays, and the equipment appeared to be actively transmitting. After that, the team traced piping and cable routes around the building and toward the Moei River.
Near the river, investigators found infrastructure tied to cargo pontoons used to move goods between Thailand and Myanmar. In several spots, the team had to dig up conduits to inspect the cables and map their paths. The work took time because the area was large and the cable paths were not easy to follow.
True said it first noticed irregular behavior through its network-monitoring and usage-analysis systems. Two service accounts, registered as companies at the same location, requested high-speed internet circuits. At first, traffic looked normal.
However, between February 22 and 25, 2026, usage spiked and stayed high around the clock, with almost no downtime. That pattern didn’t match a typical office. Also, the installation site sat next to the Moei River, directly facing Myanmar, which raised stronger concerns.
True then coordinated with the Anti-Online Scam Operation Center (ACSC), working with the Central Investigation Bureau (CIB) and the NBTC, which led to the on-site inspection and raid.
True added that the building showed clear signs of minimal day-to-day activity. Only about two to three people appeared to be stationed there. At the same time, investigators found large modified network cabinets and extra network management and gateway devices that were not standard provider equipment.
Based on the setup, True believed the building had been adapted to function as a relay node. In other words, it could receive internet service from the Thai side and forward it across the river into Myanmar. Authorities suspect the connection supported call center scam networks targeting Thai victims.
An NBTC telecom official said the agency received information that multiple internet circuits were being used in a border area where local demand is limited. When teams inspected the building, they found wiring and internal routing but could not immediately confirm the final endpoint.
Using testing tools, officials detected two circuits sending signals roughly 1 to 1.6 kilometers. Investigators said they would continue gathering proof to confirm where the signals terminated. If the service was used across the border, regulators said they would pursue charges under NBTC-related laws. They also noted that even attempting cross-border routing in this manner can still violate rules based on the overall conduct.
A cyber police investigator compared the case to a prior operation in Aranyaprathet, Sa Kaeo, in 2024, where criminals buried long cable runs underground. That earlier case involved tracing lines over several kilometers. This Mae Sot site looked more complex, but the structure and wiring suggested a similar method. Investigators said they are working to build the strongest possible case based on evidence found at the site.
True’s government relations executive said the company asked authorities to step in after internal checks showed heavy, abnormal use that didn’t fit the location. In some periods, the traffic ran 24 hours a day, which pushed the company to coordinate with enforcement teams for a closer look.
