North Korea has developed increasingly sophisticated hacking capabilities that have enabled it to steal from financial institutions and cryptocurrency exchanges and evade international sanctions, according to a new United Nations report.

Prepared by a panel of international experts, the report blamed North Korea for a broad range of sanctions-busting efforts through early February, using photos, maps and other information provided by U.N. members to document Pyongyang’s efforts to “flout” Security Council restrictions and obtain hundreds of millions of dollars.

The report supports a view among security experts that North Korea’s hacking operations can be lucrative enough for the cash-hungry regime to help counter sanctions pressure on Pyongyang to abandon its nuclear weapons program.

The regime’s revenue-generating hacking has proven to be “low-risk, high-reward and difficult to detect, and their increasing sophistication can frustrate attribution,” the report said.

In addition, the assessment said that North Korea has had success in more rudimentary smuggling techniques as illicit export of coal increased in 2019, with many of those deliveries going to China on small, ocean-faring barges.
