  • Entry in the lazarus.group DPRK IT-worker registry, which asserts that these accounts belong to one operator and gives their real citizenship as North Korea. The registry publishes no methodology, so this is recorded as its claim and not as a finding of this site. Its evidence links and its cross-references to other operators in the same registry are deliberately not reproduced as indicators.
