The D4 project is composed of various open source software to run a complete sensor network including analysing traffic to discover DDoS activities, malicious activities or even collect Passive DNS records.
D4 core software
The D4 core software are the open source software components designed to run a D4 sensor or running a complete sensor network including server, sensors and components.
- version 0.2 - D4 server is an implementation D4 server written in Python 3.6 which can handle D4 clients (sensors), manage the sensors registration and dispatch to the analyzers.
- version 0.2 - D4 client is a simple and minimal C implementation of the D4 encapsulation protocol.
- version 0.1 - d4-goclient is a D4 project client (sensor) implementing the D4 encapsulation protocol. The client can be used on different targets and architectures to collect network capture, logs, specific network monitoring and send it back to a D4 server.
D4 add-on software
D4 is composed of different building blocks which can be used depending of your need and requirements.
analyzer-d4-passivedns is an analyzer for a D4 network sensor. The analyser can process data produced by D4 sensors (in passivedns CSV format (more to come)) and ingest them into a Passive DNS server which can be queried later to search for the Passive DNS records.
- version 0.0 - analyzer-d4-passivedns
The analyzer includes a compliant Passive DNS ReST server compliant to Common Output Format.
Extract TLS certificates from pcap files or network interfaces, fingerprint TLS client/server interactions with ja3/ja3s
- version 0.0 - sensor-d4-tls-fingerprinting
analyzer-d4-pibs is a Passive Identification of BackScatter analyzer for the D4 sensor network capturing raw packet in pcap.
- version 0.0 - analyzer-d4-pibs
D4 complementary software
Complementary software which are developed in the scope of the D4 project to support security researcher, analysts and network engineers.
IP ASN History
IP ASN History is an online server and open source software to find the ASN announcing an IP range in a specific time range.
- IP ASN History source code if you want to run the service in premises. There is online interface available via the following url https://bgpranking-ng.circl.lu/ipasn_history/?ip=22.214.171.124
- BGP Ranking source code is a free software to calculate the security ranking of Internet Service Provider (ASN). There is an online version available at the following url http://bgpranking.circl.lu/
