Kuala Lumpur | December 2025
Malaysia has intensified its crackdown on illegal cryptocurrency mining operations after revealing that over US$1 billion worth of electricity was stolen in the past five years. The disclosure, made by national power utility Tenaga Nasional Berhad (TNB), has triggered a nationwide enforcement drive aimed at curbing unlicensed Bitcoin mining that is draining public resources and threatening power infrastructure.
The government has now set up a multi-agency task force to coordinate enforcement, surveillance, and policy responses as illegal mining rapidly expands across the country.
$1 Billion Power Theft Sparks Nationwide Crackdown
According to TNB, illicit miners have siphoned off electricity worth more than US$1 billion (approx INR 9000 crore), causing massive revenue losses and placing severe strain on Malaysia’s energy grid.
To detect hidden mining facilities, authorities are increasingly using:
- Drones for aerial surveillance
- Handheld thermal sensors to identify heat anomalies
- Power-consumption analytics to flag irregular usage patterns
In some cases, investigations were triggered after residents complained about strange noises—later found to be recorded bird sounds used to mask the hum of mining rigs, Bloomberg reported.
14,000 Illegal Mining Sites Uncovered
Malaysia’s Energy Ministry confirmed that more than 14,000 illegal cryptocurrency mining sites have been identified nationwide in recent years, contributing to estimated losses of US$1.1 billion for TNB.
In response, on November 19, the government constituted a special task force comprising officials from:
- Ministry of Finance
- Bank Negara Malaysia (central bank)
- Tenaga Nasional Berhad
The task force is chaired by Deputy Minister of Energy Transition and Water Transformation Akmal Nasrullah Mohd Nasir.
“The risk is no longer limited to power theft—it can directly damage our energy infrastructure. This is a serious threat to the integrity of our power system,” Akmal said.
Cat-and-Mouse Game With Illegal Miners
Cryptocurrency mining is legal in Malaysia, but only for operators who are registered and compliant with power and environmental regulations.
Under the Electricity Supply Act, offenses such as meter tampering and illegal power diversion are criminal violations, according to Channel News Asia.
Despite this, enforcement has been challenging. Illegal operators frequently:
- Shift locations between homes, warehouses and malls
- Install soundproofing, heat shields and CCTV
- Abandon sites instantly once detected
In a high-profile example, an abandoned shopping mall packed with mining rigs was discovered in 2022 but shut down only in early 2025 after a viral TikTok video exposed it.
Organised Crime Angle Under Investigation
Authorities believe the sophistication and scale of these operations point to organised criminal networks, not individual miners.
Recurring patterns include:
- Rapid setup and dismantling
- High-volume power draw
- Coordinated logistics and financing
“These are not isolated operations. The coordination suggests organised syndicates,” Akmal said, adding that police and cybercrime units are now tracking funding channels and equipment supply chains.
Bitcoin Mining Ban Being Considered
At the task force’s first meeting on November 25, officials debated whether to recommend a nationwide ban on Bitcoin mining, citing repeated abuse of power systems and infrastructure stress.
Akmal noted that even legitimate mining poses challenges:
“The volatility of crypto markets and unpredictable energy demands make regulation difficult.”
For now, Malaysia will allow licensed mining but plans stricter surveillance, tighter licensing norms, and faster enforcement actions.
Conclusion: A Harder Line on Digital Energy Exploitation
Malaysia’s sweeping crackdown reflects growing global concern over cryptocurrency’s environmental, infrastructural, and regulatory costs. With illegal miners stealing public electricity on an industrial scale, the government’s message is clear: digital assets cannot come at the expense of national utilities and public stability.
As surveillance intensifies and policy options expand, Malaysia may soon become one of the strictest enforcers against illicit crypto mining in Asia.
