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.
