The certificate names above are what the certificate ASSERTS, not proof this host owns them — a self-signed certificate can claim any subject, so treat a familiar name here as an impersonation attempt rather than an identity.

Shared TLS certificate · 4 hosts

These hosts served the same certificate. That is the strongest link this corpus can draw between two addresses, though it evidences a shared BUILD rather than a shared operator: a leaked or resold profile puts the same certificate in different hands. Full cohort →

Shared JA4X issuance template · 92 hosts

These hosts issued certificates from the same template — the same distinguished-name fields hashed in the same order. It links tooling, not necessarily an operator. Full cohort →

Samples served · 4 files

Files this address was observed DELIVERING, confirmed as malware by detonation or by analysis of the file itself. Delivery is an observation, not an attribution — a widely distributed sample can reach unrelated hosts.

Neighbourhood · 82.23.246.0/24 · 5 hosts

5 other confirmed hosts in the same /24. Adjacent addresses under one operator are a different signal from a shared certificate — they suggest a block, not a build.
