Entry in the lazarus.group DPRK IT-worker registry, which publishes this identity on a page of its own and also lists Hiroto Iwaki as a fake name on its Motoki Masuo page, filing the same address under both. It is carried here as one persona on the registry's own assertion that the two names 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.

Found on 24 September 2026 by searching GitHub's commit index for published persona addresses and reading which account GitHub attributes the commits to. GitHub credits a commit to the account that has the signing address registered and verified, which only the holder of the mailbox can do, so an attributed account is one the address's holder controls, whichever repository the commits sit in and whenever the address was added. Counts are of the commits GitHub's search returns, up to 100. GitHub attributes 100 commits signed noahsflood908@gmail.com, an address the lazarus.group registry publishes for this persona, to github.com/knownothing10, account id 146400751, created on 29 September 2023, display name Know Nothing, with 56 public repositories.
