What an Open Network Fingerprint Database Should Publish
A useful open fingerprint database needs provenance, competing labels, raw evidence, format versions and licences—not another unexplained hash list.
Does TLS Fingerprint Canonicalisation Hide Attacker Variation? How to Test It
Sorting makes TLS fingerprints more stable, but it also removes ordering evidence. Here is how to test whether the discarded variation matters.
A Network Fingerprint Is a Cohort, Not a Client
TLS fingerprints group similar protocol implementations. They do not prove which application, device or person made a request.
From Joy to Mercury and EVE: Following Cisco's Network Fingerprinting Work
Cisco's open-source collectors, fingerprinting research and Encrypted Visibility Engine form a clear lineage, but they are not interchangeable parts of one public system.
Two Lineages of TLS Fingerprinting: JA3, JA4 and Cisco Mercury
JA4 did not descend from Cisco Mercury. The two projects come from different strands of TLS fingerprinting research and solve different operational problems.
One ClientHello, Three Fingerprints: JA3, JA4 and Mercury
A reproducible lab runs JA3, JA4 and Cisco Mercury against the same TLS ClientHello and compares what each fingerprint preserves.
