  • Heiner García's post of 2 August 2025 follows Jackson Mori, whom it assesses as very probably a DPRK IT worker, through GitHub work for Router Protocol from May 2024 to March 2025 under the address jackson@routerprotocol.com, and a set of profiles on job boards that recycle one bio and a few images and claim California, Canada or Japan in turn. The portfolio at my-portfolio-pi-snowy.vercel.app gives the phone number, the jacksonmoridev0507 GitHub account and the LinkedIn profile; the dev.to and F6S profiles give Tender-Terminal, which follows the DPRK-linked BitFancy. Router Protocol gave the author the Telegram handle, and the account blocked him when he asked about the DPRK. The two X accounts use the name and reference Router Protocol.

  • Found on 18 September 2026 by taking the local part of an address this index already holds for this operator -- bluebird912 -- and asking dev.to whether an account exists under it. The address is on a consumer mail host, where the local part is a login the holder chose rather than one an employer assigned; handles taken from company addresses were excluded from this pass for that reason. The account states a registration date of 6 July 2023 and a display name of Seow Xian Jin. The login is what links this account to the rest; nothing here establishes that one person holds both, and a display name on a profile is a name the account presents, not an identification.

  • Found on 24 September 2026 by reading which account GitHub attributes commits signed willyu226@gmail.com to. GitHub credits a commit to the account that has the signing address registered, which only the mailbox's holder can arrange. willyu226@gmail.com is one of the two addresses github.com/loveFeynman signs its own commits with, under the name William Yu, and loveFeynman is filed under "GitHub accounts working in the same repositories as the Eric Liu persona". GitHub attributes the address's commits to github.com/jacksonmori, account id 133004101, created on 9 May 2023, display name Jackson Mori, whose profile describes it as a blockchain developer at Router Protocol: among them the commits in loveFeynman's own repositories self-repaying-protocol and style-transfer, from March and April 2022. The account carries the name of the persona browsercookies ties to github.com/jacksonmori755, whose portfolio duplicates loveFeynman's repositories. The holder of loveFeynman's William Yu mailbox therefore also holds an account in the Jackson Mori name, which joins the Eric Liu working circle to that persona.
