Thai Police Seize Cross-Border Fiber Cable Feeding Myanmar Scam Compound

Thai police officers intercepted an unauthorized fiber optic cable that crossed the border from Thailand into Myanmar, according to a report by SCMP cited by Tom's Hardware. The discovery occurred in Nong Lu village within Kanchanaburi province, a region known as a gateway to the Three Pagodas Pass area in Myanmar.

Investigators found a 48-core fiber optic cable with robust cabling strung along pylons for 350 meters across the international boundary. This physical link was actively siphoning internet bandwidth out of Thailand and directing it into Myanmar. The cable was connected to two ramshackle homes in the village, which were consuming enough daily bandwidth to support an entire community.

Infrastructure and Data Volume

Trairat Viriyasirikul, acting secretary general of the National Broadcasting and Telecommunications Commission, stated that the cable transmitted approximately 6 terabytes of data each day. This volume is sufficient to serve between 300 and 400 individual users. Instead of serving legitimate residents, the bandwidth was illegally routed to keep a suspected scam compound online.

The facility receiving the data reportedly housed an illegal border casino and a suspected scam center. The operation relied on local cooperation to maintain the physical connection. An unidentified male suspect was paid 700 baht, roughly $20, per day to allow the cable to run through his house. This payment suggests direct coordination with the criminal gang operating the scam center.

Regional Cybercrime Context

The incident highlights the broader security challenges in the border region. Myanmar has reportedly become the epicenter of the global scam trade, a role previously held by Cambodia. According to the report, Chinese scam bosses are increasingly running decentralized operations from small hotels, condominiums, and villas rather than large factory-style compounds.

The Three Pagodas Pass area is reportedly protected by ethnic armed militias that shelter these criminal enterprises. Non-governmental organizations claim that hundreds or thousands of people are trafficked and forced to work in this trade. The use of cross-border infrastructure like this fiber cable allows operators to maintain high-speed connectivity while evading direct jurisdictional oversight.

What should you do?

Security professionals should monitor network traffic for unusual bandwidth spikes that do not correlate with legitimate business activity. Organizations operating near border regions should verify the physical security of their telecommunications infrastructure to prevent unauthorized tapping or redirection.

What to do and how to stay safe: Myanmar

• Audit physical cabling routes to ensure no unauthorized connections extend outside secured premises or national borders.
• Monitor daily data usage metrics for anomalies that suggest bandwidth is being siphoned to external, unmanaged destinations.
• Verify that all internet service providers have signed contracts and that infrastructure is inspected regularly for tampering.
• Report suspicious high-bandwidth activity in rural or border areas to local telecommunications authorities and law enforcement.
