Malaysia’s Crypto Mining Crackdown Exposes $1bn Electricity Theft, Shifts to Data-Led Enforcement

Malaysian authorities have seized 75,578 cryptocurrency mining machines and arrested 629 people across 3,049 raids since 2022, according to figures presented to parliament, as the government moves towards smart-meter surveillance to curb electricity theft that has cost the national utility more than $1 billion.

Datuk Seri Dr. Shamsul Anuar Nasarah, a deputy home minister, disclosed the figures during Ministry Question Time in the Dewan Rakyat, the lower house of parliament, according to Bernama and The Star. The data, current as of May 2026, reflects a joint enforcement effort involving the Royal Malaysian Police, national utility Tenaga Nasional Berhad (TNB), the Energy Commission and local councils.

Utility losses drive enforcement priorities

TNB has stated that illegal power consumption tied to crypto mining across roughly 14,000 locations cost the utility more than 4.6 billion ringgit, approximately $1.1 billion, between 2020 and August 2025. The company recorded a near-300% rise in detected theft cases between 2018 and 2024, with incidents climbing from 610 to 2,397 over that period, Cryptopolitan reported in November 2025.

Mining operations are attractive targets for illicit power use because of their continuous, heavy energy draw. Shamsul told parliament that operators frequently tamper with meters to conceal actual consumption, inflating costs across the grid and destabilising supply to neighbouring homes and businesses.

Legal status of mining remains unsettled

Malaysia permits individuals to own and trade digital assets, which fall under the oversight of the Securities Commission Malaysia, while Bank Negara Malaysia, the central bank, does not recognise cryptocurrency as legal tender and focuses on financial stability and anti-money-laundering enforcement. The country has no dedicated statute governing crypto mining itself.

Instead, Shamsul said operations become unlawful when they rely on unauthorised electricity connections, tampered meters, disrupted supply infrastructure, or unlicensed operations — offences prosecuted under the Electricity Supply Act rather than any crypto-specific legislation. He added that gains from token price movements do not diminish the seriousness of the underlying offence.

Shift towards intelligence-led raids

Lawmaker Datuk Siti Zailah Mohd Yusoff pressed the ministry over what she characterised as a shortfall in prosecutions relative to the scale of raids. Shamsul responded that enforcement would increasingly rely on intelligence sharing and technology to identify high-risk areas ahead of operations, enabling what he described as a “faster and more precise” response.

TNB has been rolling out smart meters capable of flagging tampering or abnormal usage patterns in real time, part of a broader effort to move enforcement from reactive raids towards predictive monitoring. Shamsul also addressed earlier allegations concerning raids in Manjung, Perak, stating investigators found no evidence implicating police officers, agents, or municipal council members in unlawful conduct there.

The scale of Malaysia’s enforcement effort underscores a wider regional pattern in which the energy intensity of proof-of-work mining collides with subsidised or state-controlled power tariffs, creating incentives for illicit tapping that utilities and regulators are increasingly addressing through data-driven surveillance rather than legislation targeting digital assets directly.
