A man in Taiwan has been arrested over claims he mined millions of dollars’-worth of cryptos using stolen power.

According to a report from EBC Dongsen News on Wednesday, a man with the surname Yang is suspected of stealing electricity valued at over NT$100 million ($3.25 million) via his various business premises to mine bitcoin and ether, reaping around the same amount in mining profits.

Yang reportedly tapped the power supply at 17 stores in Taiwan for his illicit crypto mining operations. He would first rent an internet cafe or a toy store, then hire electricians to redesign the wiring so that the stolen electricity would not be metered, the report alleges.

Taiwan Power Company, the island’s state-owned utility provider, first discovered the operations after noticing an unstable power supply and launching an investigation. Yang was suspected and subsequently arrested by the police.

Wang Zhicheng, deputy head of the fourth brigade of Taiwan’s Criminal Investigation Bureau said in the article:

“The group recruited electricians who managed to break into the sealed meters in order to add in private lines to use electricity for free before that usage reaches the meters.”

Several such cases of mining using stolen power have emerged recently, as easy gains have proven too much of a temptation for some. Last month, two principals at a Chinese school got in hot water after stealing electricity from the institution to mine ether.

Back in June, police in the eastern Chinese province of Anhui arrested a man for allegedly stealing a significant amount of power for bitcoin and ether mining, after the local power grid company reported a spike in electricity use. And, in April, six individuals were arrested in China’s Tianjin region over claims they used 600 cryptocurrency miners to generate bitcoin with power taken from the local power grid.

According to the Taipei Times, Taipei Medical University launched a blockchain platform to improve patient referral services and integrate personal healthcare networks to make it easier for people to access their medical records.

The hospital gave a statement that the healthcare blockchain platform was developed as a one-stop referral and long-term care service to support government’s tiered health care system policy. With these improvement patient referral services and integration of personal medical networks would make it easier for people to access medical records. Hospital can record their records, patients can log in to a password-protected mobile app.

The project involves more than 100 clinics that deploy blockchain technology to address common pain points in the healthcare sector, such as data transmission between medical institutions and patient portals. Through the platform, patients have access to “a complete set of all medical records, including high-resolution medical images, laboratory results, and clinical and health check information,” while hospitals and clinics can use smart requests to authorize and share patient records.

Hospital chief Chen Ray-jade (Chen Ruijie) said in an interview that blockchain will help minimize the risk of security breaches and “blockchain technology will not only consolidate electronic medical records and the combination of multiple hospitals and clinics’ electronic health records, it also incorporates additional security with any pre-transfer notifications and agreed additional security features.” As a result, people will no longer need to go through a long wait for the transfers.

Dr. Wang Yaoting from the Taipei Community Medical Clinic said in an interview that the platform will be a big step forward. All medical and health data for the referred patients can be obtained through the blockchain, and doctors can better understand their overall health.

Global healthcare organizations have also applied distributed ledger technology in medical data management. Earlier this month, Korean biotech company Macrogen and local technology company Bigster are developing a medical big data ecosystem that will allow secure and private storage as well as the transmission of large amounts of sensitive genomic and personal information.

Some research institutions believe that blockchain technology has a broader application space in the medical field than the financial industry.
