  • Hayden McKenzie publishes this as one of the aliases recovered from a DPRK IT worker cell's own files, on a per-alias record that gives the role it presents as Senior Java Full Stack Engineer, and the contact details above. The record adds a number and a Telegram account from the persona's working files. The record was not on the site when this one first read it on 22 September 2026 and appeared alongside the report The Women Behind North Korea's IT Worker Operations, published on 23 September, so that is the date cited. The Telegram account t.me/jeremymichael0709 is already in this corpus from the same May 2025 Narcass3 post that carries jeremymichael0709@gmail.com, the Jeremy Michael address. The name is the identity the operation presents, not the operator's; a real person whose name or details it may have been assembled from is not the worker.

  • The first post is a bare list published under the word "btwz" with no operator named. The second post, from the same day, addresses the X accounts jeremymichael79 and Hakeohiratani directly and asks how Pyongyang is, which is the researcher treating both handles as DPRK operators. The two handles are recorded here on that basis. The list itself is still not split between them, because the posts do not say which account holds which identifier, and dividing it would be this site's inference rather than the researcher's. The first post also gives a web3.career handle, which has no indicator type in this repository. The address alexandersimmons824@gmail.com is the dominant author on the commits in this account's own GitHub repositories, recovered 2026-09-12; it is the operator's own commit address, not a forked repo's upstream author. The address audithunter821@gmail.com is the dominant author on the commits in this account's own GitHub repositories, recovered 2026-09-12; it is the operator's own commit address, not a forked repo's upstream author.
