  • Entry in the lazarus.group DPRK IT-worker registry, which asserts that these accounts belong to one operator. 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.
