  • 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.

  • Found on 24 September 2026 by searching GitHub's commit index for every personal address the lazarus.group registry gives for a persona, and keeping the accounts whose own repositories are committed with one. GitHub mints a noreply address from an account's immutable numeric id, in the form id+handle@users.noreply.github.com, so former handles below are a matter of record. github.com/markedBit is account id 8722069, created on 10 September 2014. Its commits carry 8722069+rustumatizon@users.noreply.github.com and 8722069+0xkonka@users.noreply.github.com, so it is the account lazarus.group lists for Quinn Lee as github.com/rustumatizon, and tayvano lists under the same handle, renamed twice; rustumatizon now returns not found. GitHub attributes 2,316 commits to it. Its repositories, uploaded in August 2024 and March 2025, are projects it worked on with other developers at the time, and in them it commits beside three registry personas: letteldream@gmail.com, which the registry gives for Quinn Lee, in CDP-interface (26 commits, February 2024), Brewlabs-UI and Gravita-upgrade; cloudrider.m92@gmail.com and the account firstninja111, which the registry gives for Jordan Lopez, in CDP-interface and CDP-backend; and smart.solidity@gmail.com, which it gives for Kang Tae Bok (listed at lazarus.group/team/joshua-palmer), in oasis-backend, where 35 commits between August 2023 and February 2024 carry that address.

  • 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 100 commits signed letteldream@gmail.com, an address the lazarus.group registry publishes for this persona, to the login letteldream, which no longer resolves.
