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.

From gh-fake-analyzer 1.0.2, the Ketman Project's GitHub analysis tool, run on 2026-09-29. These are signals: backdated history and several commit identities are common among ordinary developers too, and an account that shows none of them is not thereby cleared.
