Around 50% of North Korea's secretive missile program could be funded by cyberattacks and cryptocurrency theft, according to Anne Neuberger, the U.S. deputy national security adviser for cyber and emerging technology. American intelligence agencies are intensively tracking down North Korean operatives, and the U.S. Department of Treasury is working to locate stolen crypto.

Neuberger stated that President Joe Biden’s administration is “putting a lot of time and thought” into the issue. Last year, the South Korean National Intelligence Service declared that Pyongyang-backed hacker groups have stolen some $1.2 billion worth of crypto over the past five years.
