  • 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.

  • Found on 24 September 2026 by searching GitHub's commit index for every personal address the lazarus.group registry and the ZEUS-DEV-919 working document give for a persona, and keeping the accounts whose own commits are signed with one. GitHub mints a noreply address from an account's immutable numeric id, in the form id+handle@users.noreply.github.com, so former handles below are a matter of record. github.com/solover007 is account id 103972925, created on 19 April 2022, display name FullStack AI Dev. GitHub attributes 340 commits to it, and 99 of the 100 its search returns are signed cryptospaceboy00@gmail.com, an address lazarus.group gives for Dan Mao, under the author name spaceboy000; the hundredth is 103972925+spaceboy000@users.noreply.github.com, which makes spaceboy000 the account's former handle. Its repositories are committed with that address on the day they are created, LunarHopMiner on 16 January 2023 among them. The registry lists no GitHub account for this persona. The handle spaceboy000 was registered afresh on 19 July 2026 by a different account, id 306679812, which is not this one and is not filed.

In eight of the twelve repositories read they are the only commits, or all but one or two, and they are made in the days after each repository was created: coin-multi-sender, created on 12 March 2023, holds five commits of 12 to 15 March signed ananphoon823@gmail.com, and nothing else. None of the five addresses is registered to a GitHub account, which is why a search on the account's own name finds no commits, and why the account is tied to the persona by what its repositories contain rather than by its login. It is filed beside github.com/solover007, which signs with a sixth Dan Mao address.

  • 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 topstack2021a@gmail.com, an address the lazarus.group registry publishes for this persona, to the login RustBlockchainEngineer, which no longer resolves.

  • Found on 24 September 2026 by searching GitHub's commit index for every personal address the lazarus.group registry gives for a persona, and keeping the accounts whose own repositories are committed with one. GitHub mints a noreply address from an account's immutable numeric id, in the form id+handle@users.noreply.github.com, so former handles below are a matter of record. github.com/0xquantech is account id 92380384, created on 12 October 2021, display name Q, with 110 public repositories. Its repositories hold commits signed with five addresses lazarus.group gives for Dan Mao, blockchainlover2019@gmail.com, ananphoon823@gmail.com, alexwork455@gmail.com, billyrowan1980@gmail.com and topstack2021a@gmail.com, 144 of them in GitHub's search, under the author names blockchainlover2019 and Crazy. In eight of the twelve repositories read they are the only commits, or all but one or two, and they are made in the days after each repository was created: coin-multi-sender, created on 12 March 2023, holds five commits of 12 to 15 March signed ananphoon823@gmail.com, and nothing else. None of the five addresses is registered to a GitHub account, which is why a search on the account's own name finds no commits, and why the account is tied to the persona by what its repositories contain rather than by its login. It is filed beside github.com/solover007, which signs with a sixth Dan Mao address.

  • 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 topstack2021a@gmail.com, an address the lazarus.group registry publishes for this persona, to the login RustBlockchainEngineer, which no longer resolves.

  • Found on 24 September 2026 by searching GitHub's commit index for every personal address the lazarus.group registry and the ZEUS-DEV-919 working document give for a persona, and keeping the accounts whose own commits are signed with one. GitHub mints a noreply address from an account's immutable numeric id, in the form id+handle@users.noreply.github.com, so former handles below are a matter of record. github.com/solover007 is account id 103972925, created on 19 April 2022, display name FullStack AI Dev. GitHub attributes 340 commits to it, and 99 of the 100 its search returns are signed cryptospaceboy00@gmail.com, an address lazarus.group gives for Dan Mao, under the author name spaceboy000; the hundredth is 103972925+spaceboy000@users.noreply.github.com, which makes spaceboy000 the account's former handle. Its repositories are committed with that address on the day they are created, LunarHopMiner on 16 January 2023 among them. The registry lists no GitHub account for this persona. The handle spaceboy000 was registered afresh on 19 July 2026 by a different account, id 306679812, which is not this one and is not filed.
