  • Found on 28 September 2026 by asking GitHub's commit search, for each of the addresses this index holds from GitLab Threat Intelligence's reporting, which account its commits are credited to. GitHub credits a commit to the account that has registered the author address, so each account below owns the address shown; the count is the commits credited in the search's first page. dmb-dev87 holds dmbdev800@gmail.com (100); dobromirkovachev holds dobromirkovachev@outlook.com (2); dredsoft holds dredsoft@proton.me (69); dveretenov1 holds dveretenov@gmail.com (6); RisingStar522 holds dyadkovdevelop@gmail.com (11); enrique1225 holds enrique122528@hotmail.com (70); eruqulpuaro holds eruqulpuaro@gmail.com (3); devjourney2019 holds eruqulpuaro@hotmail.com (34); devsync255 holds gabriel.sanchez255@outlook.com (1); Venus0906 holds goldstar0906@outlook.com (6); srsoftwaredev015 holds greatbusinessman517@gmail.com (100); ghleoperez holds happyleonardo77@gmail.com (36); tf7tune holds harryjason19880502@gmail.com (3); dantelabs-bdm holds hidranomagica@outlook.com (1); TopManger holds hs8179189@gmail.com (9); janus9266 holds iamjanus66@gmail.com (100); 0xPEPEeth holds ignacioquesada127@gmail.com (14); Igor508 holds igorslobodyan508@gmail.com (19); Murattimadrid holds indulgenight@gmail.com (4). Where the address came from a report, the report is https://about.gitlab.com/blog/gitlab-threat-intelligence-reveals-north-korean-tradecraft/. An account was left out where the address may belong to a real person rather than the operator: a stolen-CV listing, a mirrored contributor's identity, a copied repository's upstream author, or an account with a long, verifiable history of its own.

Commit addresses this index holds

From gh-fake-analyzer 1.0.2, the Ketman Project's GitHub analysis tool, run on 2026-11-09. 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.
