Russia's Interfax News Agency reports that engineers at the All-Russian Research Institute of Experimental Physics (RFNC-VNIIEF)—the Russian Federation Nuclear Center facility where scientists designed the Soviet Union's first nuclear bomb—have been arrested for mining cryptocurrency with "office computing resources," according to a spokesperson for the Institute. "There has been an unsanctioned attempt to use computer facilities for private purposes including so-called mining," said Tatyana Zalesskaya, head of the Institute's press service.

Zalesskaya did not say how many people were detained, and the Federal Security Service (FSB) has not issued a statement on the arrests or criminal charges pending. But reports indicate that the group was caught trying to harness the lab's supercomputer to mine cryptocurrency.
