  • SOTAHire's article reports that Consensys, the company behind MetaMask, confirmed it had unknowingly engaged a contractor under the identity Tyler Knapp through a third-party staffing firm, who worked on MetaMask code from 9 March to April 2026 before the contractor's ties to the DPRK IT-worker network were found. The article ties that contractor to the GitHub account imyugioh, display name Yu-Gi-Oh!, which it traces to account id 54774811 and to the earlier logins raptor1001, ethlocker, burndai and 0xlocker, and it lists the further personas Ryan Choi, Stephen Gooden, Andrian Fadhilla and the new Ryota Suzuki with their accounts and addresses, all transcribed here. The article reports the Ryan Choi LinkedIn account and Calendly link as dead; the Calendly link is carried for the record. The Ryota Suzuki LinkedIn account was live when checked on 24 September 2026. The lazarus.group registry, which this index already holds, files blueraptor1001@gmail.com and choi.link227@gmail.com under Mauro Liu, and Raden Wilford's article, filed under that name, covers the same identity.

  • 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.

From gh-fake-analyzer 1.0.2, the Ketman Project's GitHub analysis tool, run on 2026-10-07. 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.
