Remove the specific dissector and use the Blizzard's generic one.
For the time being, keep `NDPI_PROTOCOL_WORLDOFWARCRAFT`
|
|
|
|
|
|
|
| |
Use `NDPI_OBFUSCATED_TRAFFIC` instead; this way, all the obfuscated
traffic is identified via `NDPI_OBFUSCATED_TRAFFIC` flow risk.
Disable fully-encryption detection by default, like all the obfuscation
heuristics.

(#2773)
Remove `NDPI_PROTOCOL_MAPLESTORY` and add a generic
`NDPI_PROTOCOL_NEXON`
|
|
|
|
|

This function is always called once for every flow, as last code
processing the flow itself.
As a first usage example, check here if the flow is unidirectional
(instead of checking it at every packets)
|
|
|
|
|
|
|
|
| |
This way, the `ndpiReader` output doesn't change if we change the
internal logic about the order we set/check the various flow risks.
Note that the flow risk *list* is already printed by `ndpiReader`
in order.

Prelimary change to start supporting multiple DNS transactions on the
same flow

Removing JA3C is an big task. Let's start with a simple change having an
huge impact on unit tests: remove printing of JA3C information from
ndpiReader.
This way, when we will delete the actual code, the unit tests diffs
should be a lot simpler to look at.
Note that the information if the client/server cipher is weak or
obsolete is still available via flow risk
See: #2551

We calculate HTTP entropy according to "Content-type:" header, see
`ndpi_validate_http_content()` on HTTP code

* detect `chisel` SSH-over-HTTP-WebSocket
* use `strncasecmp()` for `LINE_*` matching macros

Show JA4C and JA3S information (instead of JA3C and JA3S)
See #2551 for context

Adde basidc OS detection based on TCP fingerprint

Build fix

Changed the default to IPv4 (used to be IPv6) in case of DNS error response
|
|
Based on the paper: "Fingerprinting Obfuscated Proxy Traffic with
Encapsulated TLS Handshakes".
See: https://www.usenix.org/conference/usenixsecurity24/presentation/xue-fingerprinting
Basic idea:
* the packets/bytes distribution of a TLS handshake is quite unique
* this fingerprint is still detectable if the handshake is
encrypted/proxied/obfuscated
All heuristics are disabled by default.
