Published on 17 May 2025 in a thread the researcher opened with "Lets play a profile picture game! Here are a few fun DPRK ITW/remote worker profile pics and their associated emails." Each post in it pairs one address with the profile photograph used alongside it. This entry is one such post: the address kazuhirosasaki0805@gmail.com and the picture below it. The photograph is mirrored here because these posts are the only published record of the face an operator presented, and the accounts they came from are routinely deleted. It is not evidence of who operates the address: a profile picture in this dataset is as likely to be generated, stock, or taken from an uninvolved person. The name is this site reading the address, not a name the researcher gave: the post pairs an address with a picture and attributes neither to anybody.

Found on 24 September 2026 by searching GitHub's commit index for published persona addresses and reading which account GitHub attributes the commits to. GitHub credits a commit to the account that has the signing address registered and verified, which only the holder of the mailbox can do, so an attributed account is one the address's holder controls, whichever repository the commits sit in and whenever the address was added. Counts are of the commits GitHub's search returns, up to 100. GitHub attributes 13 commits signed kazuhirosasaki0805@gmail.com, an address browsercookies publishes for this persona, to github.com/HackerRank0805, account id 100253838, created on 23 February 2022, display name HackerRank0805, with 4 public repositories.
