  • 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.
