European Union ambassadors have reportedly received the “green light” to impose sanctions on North Korean, Russian and Chinese entities for their role in global cyberattacks, insider sources told outlet Radio Free Europe/Radio Liberty on Thursday.

According to the sources, an asset freeze is expected for North Korea’s Chosun Expo (also known as Korea Expo Joint Venture), a Dalian, China-based front company that facilitated the work of North Korean state-sponsored hacker Park Jin Hyok. Park was sanctioned by the U.S. in 2018 for his role in the WannaCry global ransomware attack.
