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.

Read on 21 September 2026 by walking the commit history of every repository on github.com/darkmandev103, an account reached because one of its repositories is a byte-for-byte copy of one held by the account this site files under ZEUS. The account is the registry's own github.com/diamondyhand under a new name: three of its commits carry the noreply address 113045708+diamondyhand@users.noreply.github.com, and 113045708 is darkmandev103's account id, so the handle the lazarus.group registry published for this persona was renamed rather than abandoned, and github.com/diamondyhand now returns nothing. Its own commits are signed masterdevv278@gmail.com 242 times, under the names diamondyhand and masterdevv278, which is the address the registry lists for the persona; the commit metadata ties handle and address to one account first-hand, which the registry entry did not show. The account was created on 7 September 2022, holds 35 repositories, and carries 1,153 followers against 2,239 followed. Nineteen further commits in its repositories are signed yeshealer <yeshealer@gmail.com> and attributed by GitHub to a second account, github.com/yeshealer; that address is on The Raven File's August 2025 list of IT-worker mailboxes, so the second account is recorded here on the strength of the list and the shared repositories, and nothing more is claimed for it. The repository that led here is a poker game: darkmandev103/poker-shuffle-game-react was created on 19 June 2023 with eight commits signed diamondyhand, and accompany1205/pocker-game, on the GitHub account filed under ZEUS, was created four days later holding the same history, its oldest commit signed diamondyhand and dated the day the first repository was made. One account's commits inside another persona's repository is the kind of link this site records between two entries rather than a reason to merge them.
