Tiger
Tiger is an alias
that 5 published sources report
in connection with IT Worker Fraud activity, which public reporting
attributes to North Korea (DPRK).
It is cited here from ZachXBT (@zachxbt) and Chollima Hunter.
The earliest of those reports is dated 2025-08-13 and the most recent 2026-09-20.
The reporting files it under the persona Tiger, alongside 19 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.

ZachXBT published a table of the fake identities this operator ran, drawn from a device an unnamed source compromised. The post states five IT workers between them operated more than thirty identities, using purchased Upwork and LinkedIn accounts and government IDs to obtain developer jobs. THE VALUES BELOW WERE READ FROM THE SCREENSHOT IN THE POST, not from text: the table is an image and exists in no machine-readable form. Each was transcribed and checked against the image by a person, and the team designation is the source's own grouping, not an inference drawn here. One value in the table is shared with another team. The GitHub account github.com/intellltech is listed twice in the image, once on the Henry Zhang row under this team and once on the Shan Shan Feng row under Dream, spelled identically in both. It is recorded against both operators because that is what the source shows; it is not a transcription error here, and it is the only value in the table that appears under two teams.

Found on 18 September 2026 by taking the local part of an address this index already holds for this operator -- henryzhang -- and asking GitLab 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 display name of Henry Zhang. 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 18 September 2026 by taking the local part of an address this index already holds for this operator -- henryzhang -- and asking Keybase 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 1 February 2020 and no display name but the handle itself. 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 18 September 2026 by taking the local part of an address this index already holds for this operator -- henryzhang -- and asking Hugging Face 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 display name of Jiahui Zhang. 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.

Read on 20 September 2026 by walking the commit history of every repository on the GitHub account github.com/solutionGuru0129, already held under this persona, and tallying the author line on every commit. A commit's author line is what the holder configured their git client with rather than anything the profile page chooses to display, so it recovers addresses the account never states. The address recorded here was not already in this index: SharpAttack0129@outlook.com authored 1492 commits across 32 of its repositories, commits as "solutionGuru0129". Each is admitted because it commits under a name the account itself uses, which is the test that separates the holder's own address from the original author of a repository copied in. Addresses belonging to unrelated developers whose work appears in these repositories are deliberately not recorded, and an address is evidence that whoever held it wrote those commits rather than proof of who holds the account.
