* Implemented nDPI TCP fingerprintLuca Deri2024-10-15
|
* Add monitoring capability (#2588)Ivan Nardi2024-10-14
| | | | | | | | | | | | | Allow nDPI to process the entire flows and not only the first N packets. Usefull when the application is interested in some metadata spanning the entire life of the session. As initial step, only STUN flows can be put in monitoring. See `doc/monitoring.md` for further details. This feature is disabled by default. Close #2583
* Added sonos dissectorLuca Deri2024-10-13

|
* Added -N option for dumping/restoring the DNS cache (when enabled)Luca Deri2024-10-10
| | | | Example ndpiReader -i en0 --cfg=dpi.address_cache_size,32768 -N /tmp/a
* Added new API calls for serializing/restoring the DNS cacheLuca Deri2024-10-10
| | | | | - bool ndpi_address_cache_dump(struct ndpi_address_cache *cache, char *path, u_int32_t epoch_now); - u_int32_t ndpi_address_cache_restore(struct ndpi_address_cache *cache, char *path, u_int32_t epoch_now);
* Added missing #defineLuca Deri2024-10-08
|
* Implemented (disabled by default) DNS host cache. You can set the cache size ↵Luca Deri2024-10-07
| | | | | | | | | | as follows: ndpiReader --cfg=dpi.address_cache_size,1000 -i <pcap>.pcap In the above example the cache has up to 1000 entries. In jcase ndpiReader exports data in JSON, the cache hostname (if found) is exported in the field server_hostname
* Add DingTalk protocol support (#2581)Vladimir Gavrilov2024-10-07
|
* Exports DNS A/AAAA responses (up to 4 addresses)Luca2024-10-02
| | | | Changed the default to IPv4 (used to be IPv6) in case of DNS error response
* Let the library returning the packet direction calculated internally (#2572)Ivan Nardi2024-09-27
| | | wireshark, lua: add basic analysis of possible obfuscated flows
* Add enable/disable guessing using client IP/port (#2569)Liam Wilson2024-09-27
| | | | | | | | Add configurable options for whether to include client port or client IP in the flow's protocol guesses. This defaults to include both client port/IP if the protocol is not guessed with the server IP/port. This is intended for when flow direction detection is enabled, so we know that sport = client port, dport = server port.
* Add some heuristics to detect encrypted/obfuscated/proxied TLS flows (#2553)Ivan Nardi2024-09-24
| | | | | | | | | | | | 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.
* buffer lenghtt is now returned by ndpi_quick_encrypt() and ndpi_quick_deecrypt()Luca Deri2024-09-24

* Added new API callsLuca Deri2024-09-24

* Add an heuristic to detect encrypted/obfuscated OpenVPN flows (#2547)Ivan Nardi2024-09-16
| | | | | | | | | | | | Based on the paper: "OpenVPN is Open to VPN Fingerprinting" See: https://www.usenix.org/conference/usenixsecurity22/presentation/xue-diwen Basic idea: * the distribution of the first byte of the messages (i.e. the distribution of the op-codes) is quite unique * this fingerprint might be still detectable even if the OpenVPN packets are somehow fully encrypted/obfuscated The heuristic is disabled by default.

* Add TRDP protocol support (#2528)Vladimir Gavrilov2024-08-25
| | | The Train Real Time Data Protocol (TRDP) is a UDP/TCP-based communication protocol designed for IP networks in trains, enabling data exchange between devices such as door controls and air conditioning systems. It is standardized by the IEC under IEC 61375-2-3 and is not related to the Remote Desktop Protocol (RDP).
