Forty-five homeowners and business operators in Malaysia are facing power bills totaling $1.9 million after discovering their identities had been stolen by tenants who used them to mine Bitcoin illegally.

According to a local news report on Friday, the victims expressed frustration during a press conference, explaining that they were unaware of the illegal activities until receiving bills from the local utility company, Tenaga Nasional Bhd (TNB), amounting to 8.5 million Malaysian ringgit (RM).
