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.

payload sha-256060a52acea6afeab974f60d96d2d415fbf56f7e993642aa1f3b23146a478bb30

The payload hash is the SHA-256 of the file this listener served when it was scanned. A host can change what it serves at any time, so this identifies a sample to look up or analyse rather than describing what it serves now. Only the response’s Content-Type claimed a download — no executable magic bytes were seen — so the bytes behind this hash are unverified.

Shared JA4X issuance template · 51 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 →

Neighbourhood · 91.219.239.0/24 · 1 host

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