* 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
* Add detection of SurfShark VPNNardi Ivan2024-09-05

* 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 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 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.

* FPC: add DPI information (#2514)Ivan Nardi2024-07-23
| | | | If the flow is classified (via DPI) after the first packet, we should use this information as FPC
* 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>

| | | | | | | | | | | | | | 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)

|
* 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
