first seen 2026-06-12 21:45 · last seen 2026-11-01 00:30 · JSON

Last 7 days (387 observations)

Distinct clients per day (last 30 days, peak 163/day)

Distinct clients are counted by IP-hash per complete UTC day — unlike observation counts this is insensitive to one chatty client, but NAT merges clients and address rotation splits them.

Co-observed signals

Signals from other families seen in the same observation. A fingerprint spread thinly across many lower-layer signatures is a classic inconsistency signal.
