Malaysia's national utility, Tenaga Nasional Berhad (TNB), has reported losses exceeding $1 billion due to electricity theft by cryptocurrency miners from 2020 to August 2025. The Ministry of Energy and Natural Resources revealed in a parliamentary response that 13,827 locations were found to have illegally modified or bypassed electricity meters for mining purposes. Although Malaysia lacks specific legislation targeting crypto mining, such activities contravene the Electricity Supply Act.
