Despite losing some steam in recent times, the cryptocurrency mining craze is still alive and kicking. Ukrainian local media reports that workers at a nuclear power plant have been caught mining cryptocurrency using the electrical power “freely” available to them from the very nuclear plant they worked at.

As the story goes, Ukraine’s Security Service (SBU) last month discovered unauthorized computer equipment at the South Ukraine Nuclear Power Station in Mykolaiv province, near the city of Yuzhnoukrainsk. The authors reportedly used their own equipment and the readily available electricity generated by the nuclear plant to conduct their operation, according to Bitdefender.

The unauthorized hardware included video cards, switches, hard disk drives and solid state drives, various power supplies and motherboards, as well as networking equipment that would have no place in their part of the facility. In fact, the reason the operation is considered such an offense is that the employees connected their mining gear to the web and may have leaked state secrets, according to the report by local news outlet internetua.com.
