  • Posted in reply to a company statement, asserting this operator was on payroll at a named firm for years. The post lists the four GitHub handles as 'GitHub alias'; they are recorded as accounts on that wording.

  • 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.

  • Found on 13 September 2026 by probing every account handle this site already holds for this operator against GitLab, and read from the profile cited. An active GitLab account exists under keisukew53, a login the index already carries for this persona on another platform. The profile gives a member-since date of 26 February 2025. It displays the name Keisuke Watanabe, the same name the reporting already gives. The handle is what links this account to the rest; nothing here establishes that one person holds both, and a display name on a profile is a name the account presents, not an identification. The profile's bio, location and links render only in a browser and were not read, so nothing is claimed about them either way.
