Malaysia Fights Back Against Crypto Mining Power Theft Causing Millions in Losses

A recent police crackdown in Malaysia has exposed a growing regional problem: illegal cryptocurrency mining operations that steal electricity while generating substantial profits for organised crime networks.

Authorities say these operations are becoming increasingly sophisticated, with criminal groups exploiting subsidised electricity, manipulating power meters and using rented properties to conceal large-scale mining activities. Beyond financial losses, the trend is placing additional pressure on national power infrastructure and raising concerns over links to money laundering, cyber fraud and other organised criminal activities.

The issue came into focus after Malaysian police raided four rented properties in Johor on 22 and 23 July, uncovering an illegal cryptocurrency mining operation running 71 machines around the clock.

Three suspects were arrested during the operation, while police seized computers, internet routers, vehicles and other equipment believed to have been used for unlawful Bitcoin mining.

According to Johor police, the syndicate bypassed electricity meters to avoid paying for power consumption, resulting in estimated losses of around €14,500 (approximately RM72,500) in just one month. Authorities also believe the operation generated monthly revenue of between €17,200 and €21,500, equivalent to roughly RM86,000 to RM108,000.

Although relatively modest compared with other cases, the raid highlights a much wider problem facing Malaysia.

According to a report by Deutsche Welle (DW), national electricity provider Tenaga Nasional Berhad (TNB) identified nearly 14,000 premises linked to electricity theft for cryptocurrency mining between 2020 and 2025. The illegal activities are estimated to have caused cumulative losses of around €1.1 billion, or approximately RM5.5 billion.

Official figures from Malaysia's Ministry of Energy also show that recorded electricity theft cases connected to illegal cryptocurrency mining rose sharply from 610 cases in 2018 to 2,397 cases in 2024, underlining the rapid expansion of the problem.

Experts believe the consequences extend well beyond unpaid electricity bills.

According to DW, Sonny Zulhuda, an associate professor at the International Islamic University Malaysia, noted that the increasing number of illegal mining operations had created serious challenges for electricity security, economic sustainability and government revenue. He also observed that enforcement efforts continued to face legal and investigative limitations as criminal methods evolved.

While cryptocurrency mining itself remains legal in many jurisdictions, authorities across Southeast Asia are increasingly uncovering connections between illegal mining operations and wider criminal networks involved in online gambling, cyber scams and money laundering.

DW reported that the United States and the United Kingdom previously imposed sanctions on Cambodia's Prince Group and related entities over allegations involving forced labour scam compounds and cryptocurrency-related money laundering. US authorities also seized Bitcoin worth approximately US$15 billion, alleging that the assets were linked to fraud and money laundering activities associated with the organisation.

Thailand has encountered similar challenges. In 2025, the country's Department of Special Investigation dismantled three major illegal cryptocurrency mining operations, confiscating more than 6,390 mining machines. The investigation estimated losses to Thailand's Provincial Electricity Authority at more than €24.9 million, or approximately RM125 million.

Indonesia has also been affected.

In December 2023, police in North Sumatra raided ten illegal mining sites and confiscated more than 1,100 Bitcoin mining machines. State electricity company PT PLN estimated that electricity theft had caused losses of around €700,000, equivalent to roughly RM3.5 million, over six months.

Governments throughout Southeast Asia have responded by strengthening enforcement through coordinated operations involving police, energy providers and financial regulators. Malaysia has introduced a multi-agency task force and deployed smart meter technology to identify abnormal electricity consumption that may indicate illegal mining activities.

Despite these measures, enforcement remains difficult. Mining equipment can be moved quickly, rented properties are often registered through intermediaries and electricity meter tampering may involve organised criminal networks or insider assistance.

Telecommunications expert Saaidal Razalli Azzuhri of the University of Malaya suggested that authorities should strengthen monitoring systems, require licensing for mining operators, improve transparency over company ownership and monitor cryptocurrency wallets alongside financial transactions. Rather than banning blockchain technology, he argued that the priority should be ensuring that cryptocurrency miners bear the full cost of the electricity they consume.

Laos provides another example of the challenges facing governments seeking to benefit from cryptocurrency mining.

In 2021, the country authorised six companies to mine and trade cryptocurrencies, hoping to capitalise on its abundant hydropower resources. At its peak, the industry consumed approximately 500 megawatts of electricity. However, officials later concluded that the sector generated limited employment and delivered fewer long-term economic benefits than industries such as manufacturing, electric vehicle production, artificial intelligence data centres and electricity exports.

The experience highlights an important lesson for policymakers. While low electricity costs may attract cryptocurrency miners, sustainable economic growth depends on whether those investments create meaningful value. When operators steal electricity or rely on heavily subsidised power without delivering wider economic benefits, the financial burden ultimately falls on governments, utility providers and taxpayers.

Malaysia remains one of the region's most active cryptocurrency markets, making it an attractive target for illegal mining syndicates. The sharp rise in electricity theft cases demonstrates how organised crime is exploiting the country's energy infrastructure to generate illicit profits. These losses ultimately affect electricity providers, public finances and consumers, who may bear higher costs through infrastructure upgrades and enforcement efforts. As neighbouring countries continue to face similar threats, stronger regional cooperation will be essential to disrupt criminal networks that operate across borders.
