Fingerprint family: 2 shapes, 7 IPs, 9 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, 11 headers, no body, 6 outside the core list: connection, accept-encoding, user-agent, host, x-forwarded-for, cf-ipcountry, cf-visitor, x-forwarded-proto, cdn-loop, cf-connecting-ip, cf-ray

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.
