TCP SYN (JA4T)
32768_2-1-3-4-8_1460_10
first seen 2026-07-11 05:09 · last seen 2026-10-30 12:08 · JSON
Last 7 days (9 observations)
Distinct clients per day (last 30 days, peak 33/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.
