* Add (kind of) support for loading a list of JA4C malicious fingerprints (#2678)Ivan Nardi2025-01-14
| | | | | | | | | It might be usefull to be able to match traffic against a list of suspicious JA4C fingerprints Use the same code/logic/infrastructure used for JA3C (note that we are going to remove JA3C...) See: #2551
* Improved WebSocket-over-HTTP detection (#2664)Toni2025-01-11
| | | | | | * detect `chisel` SSH-over-HTTP-WebSocket * use `strncasecmp()` for `LINE_*` matching macros Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* QUIC: remove extraction of user-agent (#2650)Ivan Nardi2025-01-07
| | | | | In very old (G)QUIC versions by Google, the user agent was available on plain text. That is not true anymore, since about end of 2021. See: https://github.com/google/quiche/commit/f282c934f4731a9f4be93409c9f3e8687f0566a7
* Add the ability to enable/disable every specific flow risks (#2653)Ivan Nardi2025-01-06
|
* QUIC: extract "max idle timeout" parameter (#2649)Ivan Nardi2025-01-06
| | | | | Even if it is only the proposed value by the client (and not the negotiated one), it might be use as hint for timeout by the (external) flows manager
* Removed old USE_LEGACY_AHO_CORASICK codeLuca Deri2024-11-26
|
* Update `flow->flow_multimedia_types` to a bitmask (#2625)Ivan Nardi2024-11-25
| | | In the same flow, we can have multiple multimedia types
* RTP, STUN: improve detection of multimedia flow type (#2620)Ivan Nardi2024-11-19
| | | | Let's see if we are able to tell audio from video calls only looking at RTP Payload Type field...

| | | Extend configuration of raw format of JA4C fingerprint
* 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
|
* 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
|
* 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.
* Allow IP guess before port in ndpi_detection_giveup (#2562)Liam Wilson2024-09-20
| | | | Add dpi.guess_ip_before_port which when enabled uses classification by-ip before classification by-port.
* 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.
* Implemented JA4 raw (ja4_r) fingerprintLuca Deri2024-09-05
| | | | | Example: ./example/ndpiReader -i tests/pcap/safari.pcap --cfg=tls,metadata.ja4r_fingerprint,1
* OpenVPN, Wireguard: improve sub-classificationNardi Ivan2024-09-05
| | | | | | | | Allow sub-classification of OpenVPN/Wireguard flows using their server IP. That is useful to detect the specific VPN application/app used. At the moment, the supported protocols are: Mullvad, NordVPN, ProtonVPN. This feature is configurable.
* Add Lustre protocol detection support (#2544)Vladimir Gavrilov2024-09-04
|
* HTTP, QUIC, TLS: allow to disable sub-classification (#2533)Ivan Nardi2024-09-03
|
* 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).
* Add Automatic Tank Gauge protocol (#2527)wssxsxxsx2024-08-23
| | | | | | | See also #2523 --------- Co-authored-by: Nardi Ivan <nardi.ivan@gmail.com>
* Add CNP/IP protocol support (#2521)Vladimir Gavrilov2024-08-22
| | | ISO/IEC 14908-4 defines how to tunnel Control Network Protocol (CNP) over IP networks. It encapsulates protocols like EIA-709, EIA-600, and CNP, making it a versatile solution for building automation and control systems.
* Add OpenWire support (#2513)Vladimir Gavrilov2024-07-22
|
* FPC: small improvements (#2512)Ivan Nardi2024-07-22
| | | | Add printing of fpc_dns statistics and add a general cconfiguration option. Rework the code to be more generic and ready to handle other logics.
* FPC: add DNS correlation (#2497)mmanoj2024-07-22
| | | | | | | | | Use DNS information to get a better First Packet Classification. See: #2322 --------- Co-authored-by: Nardi Ivan <nardi.ivan@gmail.com>
* Add Nano (XNO) protocol support (#2508)Vladimir Gavrilov2024-07-18
|
* fuzzing: improve coverage (#2495)Ivan Nardi2024-07-12
| | | | | | | | | | | | | | Fix detection of WebDAV and Gnutella (over HTTP) Fix detection of z3950 Add two fuzzers to test `ndpi_memmem()` and `ndpi_strnstr()` Remove some dead code: * RTP: the same exact check is performed at the very beginning of the function * MQTT: use a better helper to exclude the protocol * Colletd: `ndpi_hostname_sni_set()` never fails Update pl7m code (fix a Use-of-uninitialized-value error)
* Improve detection of Cloudflare WARP traffic (#2491)Ivan Nardi2024-07-04
| | | See: #2484
* Add Ripe Atlas probe protocol. (#2473)Toni2024-06-17
| | | Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Zoom: remove "stun_zoom" LRU cacheNardi Ivan2024-06-17
| | | | | Since 070a0908b we are able to detect P2P calls directly from the packet content, without any correlation among flows
* Added protocol - JRMI - Java Remote Method Invocation (#2470)Mark Jeffery2024-06-15
|
* RTP/STUN: look for STUN packets after RTP/RTCP classification (#2465)Ivan Nardi2024-06-07
| | | | | | | | | | After a flow has been classified as RTP or RTCP, nDPI might analyse more packets to look for STUN/DTLS packets, i.e. to try to tell if this flow is a "pure" RTP/RTCP flow or if the RTP/RTCP packets are multiplexed with STUN/DTLS. Useful for proper (sub)classification when the beginning of the flows are not captured or if there are lost packets in the the captured traffic. Disabled by default
* Zoom: faster detection of P2P flows (#2467)Ivan Nardi2024-06-07
|
* RTP: fix detection over TCP (#2462)Ivan Nardi2024-05-29
| | | | | | RFC4571 is not the only way to wrap RTP messages in TCP streams. For example, when RTP is encapsulated over TURN flows (i.e. via DATA attribute) there is no additional framing. See also 6127e0490
* Add ZUG consensus protocol dissector. (#2458)Toni2024-05-28
| | | Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Added dpi.compute_entropy configuration parameterLuca Deri2024-05-18

* Cleaned up APILuca Deri2024-05-17
| | | | | | | | | Removed - int ndpi_load_ipv4_ptree_file(ndpi_ptree_t *tree, const char *path, u_int16_t protocol_id); - int ndpi_load_ipv6_ptree_file(ndpi_ptree_t *tree, const char *path, u_int16_t protocol_id); Added (it supports both IPv4 and v6) + int ndpi_load_ptree_file(ndpi_ptree_t *tree, const char *path, u_int16_t protocol_id);
* Add Call of Duty Mobile support (#2438)Vladimir Gavrilov2024-05-15

* Add Ethernet Global Data support (#2437)Vladimir Gavrilov2024-05-11
|
* Raknet/RTP: avoid Raknet false positives and harden RTP heuristic (#2427)Ivan Nardi2024-05-09
| | | | | | | | | There is some overlap between RTP and Raknet detection: give precedence to RTP logic. Consequences: * Raknet might require a little bit more packets for some flows (not a big issue) * some very small (1-2 pkts) Raknet flows are not classified (not sure what do do about that..)
* Added #ifdef for Windows builds (#2431)Luca Deri2024-05-09
