This fingerprint is concentrated: many addresses on very few networks, which is what a single coordinated operation tends to look like.

Fingerprint family: 2 shapes, 46 IPs, 94 events in 30 days
Every shape here is within one request header of the family's largest shape and comes from the same source addresses. One tool, several request shapes; a hashed fingerprint shows these as unrelated.
HTTP/1.1, 15 headers, no body: accept, connection, accept-encoding, host, accept-language, upgrade-insecure-requests, user-agent, sec-fetch-mode, sec-fetch-dest, sec-fetch-site, sec-fetch-user, sec-ch-ua-platform, sec-ch-ua-mobile, sec-ch-ua, sec-gpc

About this fingerprint
Akin fingerprints an HTTP client from the request head alone: the protocol version, line endings, body framing, which headers are present, and the grammar of the negotiation header values. The User-Agent string and the request path are deliberately excluded, because both are trivially changed and both were measured varying within a single operator, so a scanner that rotates either keeps one fingerprint. The middle section is a presence bitmap rather than a hash, so two tokens can be compared directly to see how many headers the clients differ by.
