first seen 2026-06-11 23:07 · last seen 2026-09-16 10:52 · JSON

Last 7 days (557 observations)

Distinct clients per day (last 30 days, peak 259/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.
