North Korea cyber nuclear Russia UN sanctions.

North Korean hackers have stolen billions of dollars by breaking into cryptocurrency exchanges and by creating fake identities to get remote jobs for foreign tech firms, a new report finds. The investigation comes from a monitoring group set up by the U.S. and 10 other nations to watch North Korea for any violations of U.N. sanctions on its nuclear program. In a report published Wednesday the group found that North Korea is also using cryptocurrencies to launder money and pay for military purchases to avoid international scrutiny. The monitoring group was set up last year after Russia vetoed continued monitoring by the U.N. Security Council.
