Malaysian police dismantled a Bitcoin mining syndicate in Johor after four raids on July 22 and 23 across rented premises linked to illegal electricity connections, according to details reported by local media and authorities.

Tenaga Nasional Berhad (TNB), Malaysia’s national electricity utility, took part in the operation, which targeted four premises and led to the arrest of three local men. Authorities seized 71 cryptocurrency mining rigs and said the operation was capable of generating an estimated RM80,000 to RM100,000, or about $25,000, in monthly profits.

The raid, codenamed Ops Letrik, highlighted the recurring role of electricity theft in illegal cryptocurrency mining cases in Johor. Bitcoin mining relies on a proof-of-work consensus mechanism that demands continuous computational power, making electricity the single largest operating expense for any mining operation. By bypassing legitimate power meters, mining operators can avoid that cost entirely, leaving TNB to absorb the losses.

Malaysia does not prohibit cryptocurrency activities outright — the Securities Commission Malaysia regulates digital asset trading and exchanges — but unlicensed mining operations that steal electricity fall outside that regulatory framework and are treated as criminal enterprises.

At the time the case was reported, Bitcoin USD was down 0.4% over the previous 24 hours, trading at $65,300 after falling below the $66,000 level the day before. The source report said support at $65,000 was holding at that time.

How the Johor Syndicate Operated

The operation was conducted by the Criminal Investigation Department (D4) of the Johor Contingent Police Headquarters in collaboration with TNB’s Southern Region SEAL team.

The raids covered three residential houses and one shophouse in Iskandar Puteri, Johor Bahru Utara, and Kulai. Each property was rented for between RM5,000 and RM6,000 per month, and police said the rental arrangements remained under active investigation.

Authorities said the syndicate used direct tapping methods to bypass legitimate TNB meters. The hardwired connections allowed the Bitcoin mining equipment to operate without electricity bills being paid through normal channels.

Police said the mining sites had operated for about one month before the raids. During that period, the electricity theft caused RM67,502.30 in losses to TNB.

Seized items included 71 cryptocurrency mining machines, two computers, two laptops, five routers, two monitors, two keyboards, one mobile phone, and two vehicles.

Johor police chief Datuk Ab Rahaman Arsad said one suspect served as the manager overseeing activity across all four premises. The other two suspects were described as external technicians responsible for wiring work and installing the mining machines.

Ab Rahaman said initial investigations found that the syndicate could generate profits of between RM80,000 and RM100,000 per month. The suspects are believed to have been paid around RM5,000 per month.

All three suspects, aged between 26 and 46, were remanded until July 26. Police said they were continuing efforts to identify and track additional individuals linked to the network.

Legal Exposure and Johor’s Enforcement Record

The case is being investigated under two statutes. Section 427 of the Penal Code, covering criminal mischief, carries a prison term of between one and five years, a fine, or both upon conviction. Section 37(1) of the Electricity Supply Act 1990, covering interference with electrical installations, carries a fine of up to RM100,000, imprisonment of up to five years, or both.

The Johor case is part of a broader enforcement pattern involving illegal cryptocurrency mining and electricity theft in Malaysia. Between January 2025 and June 2026, Johor Contingent Police raided 16 premises linked to illegal cryptocurrency mining, seized 158 machines in total, and recorded TNB losses of nearly RM1 million.

The July 22–23 operation involved 71 mining machines and estimated TNB utility losses of RM67,502.30. While the number of machines was smaller than in some earlier enforcement actions, the operating structure described by authorities was similar: rented premises, modified electrical connections, and mining equipment running outside normal billing systems.

Malaysia’s Broader Power Theft Problem

The Johor raid forms part of a sustained national enforcement campaign against electricity theft tied to cryptocurrency mining. In such cases, authorities say illegal operators shift a major operating cost onto the public grid by bypassing metered electricity supply.

Bitcoin mining normally requires substantial and continuous electricity consumption, making power costs a central factor in the economics of the activity. When operators avoid paying commercial electricity rates, marginal or loss-making mining activity can become profitable, while the utility bears the financial loss.

The latest Johor case also illustrates the distinction between licensed or above-board cryptocurrency operations and illicit mining sites that rely on unauthorized electrical connections. Legitimate operators must manage electricity costs and other operating expenses through standard commercial arrangements, while illegal syndicates externalize those costs through meter bypasses and direct tapping.

Johor police said they are continuing to track additional suspects connected to the syndicate, indicating that the network may extend beyond the three men currently in custody.
