KGJ
KGJ is an alias
that 8 published sources report
in connection with IT Worker Fraud activity, which public reporting
attributes to North Korea (DPRK).
It is cited here from Cookie Connoisseur (@browsercookies) and Chollima Hunter.
The earliest of those reports is dated 2025-06-14 and the most recent 2026-09-29.
The reporting files it under the persona KGJ, alongside 55 other identifiers attributed to the same identity. The persona page shows them together with any accounts, photographs and CV recorded under that name. A persona name is the one an account presented under, and may belong to an uninvolved person whose identity was taken.

The researcher presents all of these accounts as one operator, given only by the initials KGJ, across four posts on the same day. The first lists the X and GitHub accounts, the second names the identities Lendon Bracewell, John Faryno, Flavio Santos and Felix Martel and links a PeoplePerHour freelancer profile, and the last two list the addresses. Both spellings dev0825conscientious and dev0825conscientiouos are transcribed as published; the second looks like a typo the operator made, and correcting it would invent an address. Several of these accounts already reach this site from tayvano's research repository and the lazarus.group registry, so those records carry both citations.

Found on 13 September 2026 by probing every account handle this site already holds for this operator against GitLab, and read from the profile cited. An active GitLab account exists under 0xapp123, a login the index already carries for this persona on another platform. The profile gives a member-since date of 26 January 2026. It displays "0xapp123", which is a display name rather than a person's name and is recorded here rather than as an alias. The handle 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. The profile's bio, location and links render only in a browser and were not read, so nothing is claimed about them either way.

Found on 13 September 2026 by probing every account handle this site already holds for this operator against GitLab, and read from the profile cited. An active GitLab account exists under 0xnevo, a login the index already carries for this persona on another platform. The profile gives a member-since date of 26 February 2025. It displays the name Felix Martel, which no source this site holds had attached to this operator before. The handle 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. The profile's bio, location and links render only in a browser and were not read, so nothing is claimed about them either way.

Found on 13 September 2026 by probing every account handle this site already holds for this operator against dev.to, and read from the profile's own public API. An account exists under 0xapp123, a login the index already carries for this persona on another platform. It gives a joined date of Jul 22, 2025. It displays "0xapp123", a display name rather than a person's name. The profile links a GitHub account, 0xapp123. The handle 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 18 September 2026 by taking the local part of an address this index already holds for this operator -- johnfaryno -- 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 26 February 2026 and a display name of John Faryno. The display name is kept here rather than carried as an alias, because it restates the handle, describes the work, or is too bare to be a name. 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 searching GitHub's commit index for every personal address this index transcribes from researchers' posts, and keeping the accounts whose own commits are signed with one. GitHub mints a noreply address from an account's immutable numeric id, in the form id+handle@users.noreply.github.com, so the former handles below are a matter of record. Counts of an account's own commits are over the 100 that GitHub's search returns for it. github.com/BillionaireBB97 is account id 125123604, created on 11 February 2023, with 157 public repositories. Its commits carry noreply addresses under the handles 0xnevo and comet19950902, so it is the account browsercookies names as github.com/0xnevo under KGJ, renamed; 0xnevo now returns not found. Its own commits are signed goodluckydev@gmail.com (60 of 100) and theo.murray.nevo@gmail.com, the former handle in a mailbox. Its repositories also hold 66 commits signed dev0825conscientious@gmail.com, an address the same researcher gives for KGJ, and a few signed with addresses other researchers give for whisdev and rarosem.

Found on 24 September 2026 by searching GitHub's commit index for the addresses researchers give for this persona, and for the addresses of the accounts already filed under it. Counts of an account's own commits are over the 100 that GitHub's search returns for it. github.com/memedev365 is account id 204901096, created on 25 March 2025, and signs its own commits memedev365@outlook.com. Five of its nine repositories were read, all created on the day the account was, and in each the account's own first commit is joined the same day by one signed 0xNevo, goodluckydev@gmail.com, which GitHub attributes to github.com/BillionaireBB97, the account filed under KGJ that was previously named 0xnevo; in puffdog-nft-mint-be the two are at 18:37 and 19:35 UTC. The KGJ account pushing into every repository of a new account on its first day is recorded here as the persona operating it, as with the other accounts whose repositories are opened by a persona's identity.

Found on 29 September 2026 by searching GitHub's code for the handles this site already holds for the persona (super1114, topsecretagent007, 0xapp123) and reading the files that name them: contact blocks, profile READMEs and portfolio data in the persona's own repositories or in repositories that credit its accounts. Each value is cited to the file it was read from. Values in copied templates, client team pages and test data are not carried.
