Same tool, different options

These 54 other fingerprints share this one's JA4_c — the extension and signature-algorithm hash. A client that keeps its extension set constant while varying its cipher list produces exactly this pattern, which is what a scanner iterating cipher suites looks like. A JA3 cannot show you this: its single MD5 collapses ciphers and extensions together, so every variation looks like an unrelated client.

The hello it was computed from

Recovered because the proxy now stores the pre-hash JA3 string alongside the digest. Every number below came out of this client's ClientHello; anything we cannot name in the IANA registry is shown as its raw value rather than guessed at.

This entry is an observation, not a policy decision. It is here because the edge saw it, not because anyone reviewed it, and it blocks nothing on its own. Only the curated tier drives classification and banning.
