* 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 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.

* Added Sonos protocol detectionLuca Deri2024-09-24

* TLS: improve handling of Change Cipher message (#2564)Ivan Nardi2024-09-23
|
* 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
* Added fix for handling Server Hello before CLient HelloLuca2024-09-17

* Fixed handling of spurious TCP retransmissionsLuca2024-09-17
|
* 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.
* Add detection of NordVPNNardi Ivan2024-09-05

* OpenVPN: improve detectionNardi Ivan2024-09-05

* Add Lustre protocol detection support (#2544)Vladimir Gavrilov2024-09-04

* Align serialized risk names to all others (first letter; uppercase letter) ↵Toni2024-09-03

* 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.
* Fix CNP-IP false positives (#2531)Vladimir Gavrilov2024-08-30
|
* 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).
