Threat actors with ties to the Democratic People's Republic of Korea (aka DPRK or North Korea) have been observed seeking job opportunities beyond the information technology (IT) sector, with recent investigations identifying suspected workers employed in sales and marketing and the medical profession.
The ongoing insider threat is part of what has been described as the IT worker scheme, where North Korea leverages its network of skilled IT workers, both within and outside the country, to fraudulently land jobs in Fortune 500 companies and private sector firms across the world and remotely earn income to further Pyongyang's unlawful nuclear weapons and ballistic missile programs.
This entails relying on stolen or forged identity documents, VPNs, and proxy services to mask their true identity and location. The yearslong campaign is also tracked under the monikers Famous Chollima, Jasper Sleet, Nickel Tapestry, PurpleDelta (formerly TAG-121), UNC5267, and Wagemole.
"DPRK workers present a unique detection challenge for defenders: rather than compromising accounts or breaking in via gaps in the organizations' environments, they're tricking companies into remotely hiring them, and oftentimes actually doing the legitimate work they were hired to do," Huntress said in an analysis.
