* STUN: fix monitoring of Whatsapp and Zoom flows (#2590)Ivan Nardi2024-10-15
|
* 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

* 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
* TLS: detect abnormal padding usage (#2579)Ivan Nardi2024-10-01
| | | | Padding is usually some hundreds byte long. Longer padding might be used as obfuscation technique to force unusual CH fragmentation
* TLS: heuristics: fix memory allocations (#2577)Ivan Nardi2024-09-30
| | | | Allocate heuristics state only if really needed. Fix memory leak (it happened with WebSocket traffic on port 443)
* 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.

* TLS: improve handling of Change Cipher message (#2564)Ivan Nardi2024-09-23
|
* 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.
* Tls out of order (#2561)Ivan Nardi2024-09-18
| | | | | | | | | | | | * Revert "Added fix for handling Server Hello before CLient Hello" This reverts commit eb15b22e7757cb70894fdcde440e62bc40f22df1. * TLS: add some tests with unidirectional traffic * TLS: another attempt to process CH received after the SH Obviously, we will process unidirectional traffic longer, because we are now waiting for messages in both directions

* dns: add a check before setting `NDPI_MALFORMED_PACKET` risk (#2558)Ivan Nardi2024-09-16
| | | | | | "Invalid DNS Header"-risk should be set only if the flow has been already classified as DNS. Otherwise, almost any non-DNS flows on port 53 will end up having the `NDPI_MALFORMED_PACKET` risk set, which is a little bit confusing for non DNS traffic
* 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.
* QUIC: add a basic heuristic to detect mid-flowsNardi Ivan2024-09-10

* RTMP: improve detection (#2549)Ivan Nardi2024-09-10
|
* oracle: fix dissector (#2548)Ivan Nardi2024-09-07
| | | | We can do definitely better, but this change is a big improvements respect the current broken code
* Add detection of Windscribe VPNNardi Ivan2024-09-05
|
* Add detection of CactusVPNNardi Ivan2024-09-05

* 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.

* Bittorrent: improve detection of UTPv1 and avoid false positivesNardi Ivan2024-09-03
|
* Bittorrent: fix extra dissectionNardi Ivan2024-09-03
| | | | | | | On extra-dissection data-path we only need to look for the hash (the flow is already classified as Bittorrent). As a nice side-effect, the confidence is now always with the right value.
* HTTP, QUIC, TLS: allow to disable sub-classification (#2533)Ivan Nardi2024-09-03
