North Korea continued to develop its nuclear and ballistic missile programs during the past year and cyberattacks on cryptocurrency exchanges were an important revenue source for Pyongyang, according to an excerpt of a confidential United Nations report seen on Saturday by Reuters, APA reports.

The annual report by independent sanctions monitors was submitted on Friday evening to the U.N. Security Council North Korea sanctions committee.

“Although no nuclear tests or launches of ICBMs (intercontinental ballistic missiles) were reported, DPRK continued to develop its capability for production of nuclear fissile materials,” the experts wrote.

North Korea is formally known as the Democratic People’s Republic of Korea (DPRK). It has long-been banned from conducting nuclear tests and ballistic missile launches by the U.N. Security Council.
