  • Raden Wilford's article maps the commit history of the identity the lazarus.group registry files as Mauro Liu: 1,558 commits over seven years across 68 repositories and seventeen organisations, including Harmony, MetaMask and DefiLlama. It binds the GitHub account imyugioh, id 54774811, and its former logins raptor1001, ethlocker, 0xlocker and burndai by noreply addresses; adds 0xllaCh, which holds the contract work; and adds a second account, id 39268153, with the logins gmspacex, holy-pengy, 0xMars, zeusdice and firekingsid, which it ties to the mauroliu77 half by 279 of 279 matching author times and tree hashes. It records that commits under one address declared Asian and Western clocks on forty-four days of the same repository, which it reads as more than one operator on one identity, and it states that no exploit is attributed to the identity. The article names daiki-iu, a collaborator on HedgePie, as a registry alias of the persona; that is carried only in this note. Its X handles 0xchamel and zhExcal and the alias Xu Liu are what the article reports the registry entry to carry.

  • 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 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 choi.link227@gmail.com, an address the lazarus.group registry publishes for this persona, to github.com/wpickachu, account id 50459820, created on 9 May 2019, display name It's me!, with 86 public repositories.

  • Found on 24 September 2026 by reading which account GitHub attributes commits to for the addresses in the identity register Raden Wilford published with his article on this identity (the second post). GitHub credits a commit to the account that has the signing address registered, which only the mailbox's holder can arrange. holypengy@gmail.com, one of the addresses the register lists, is attributed on 220 commits to the login winy-pengy, which no longer resolves; holy.pengy@gmail.com, another address it lists, is attributed on 26 commits to github.com/frankuin, account id 160151424, created on 15 February 2024 with one public repository; and firek7731@gmail.com, which the article gives for its second account, id 39268153, is attributed on 273 commits to the login ahadoodle, which no longer resolves. The commits sit in client projects the identity worked on, among them the Frankencoin and Oracle Free Dollar repositories, which are not carried as indicators.
