  • One post listing three names together with a single pool of addresses, phone numbers, accounts and portfolio sites, under the heading the researcher gives it. The post does not say which value belongs to which name, and it does not say the three are one operator, so only the values that name a person themselves are attributed. Everything else is recorded as a group. Independently, Group-IB's research on a reusable persona shell it tracks as cybersage14 names Dejan-Teofilovic as an identity that account shifted to, and the GitHub account under that name was already indexed from that report; this post is a second, separate citation for it.
