Documentation

The miner script is a powerful data mining tool that helps users discover and build relationships between various entry points in a graph oriented fashion. Multiple sources of data already are implemented using a modular plugin system. and can be easily integrated using a modular plugin system.

Before digging too deep into the miner details, it is important to see the big picture. At OpenDNS, we build the "Security Graph". This security graph can be seen as a complex relational database representing Internet entities (Domains, IPs, ASNs, Whois ...) built on one hand from our DNS logs, on the other hand from external parties (Whois DB, MaxMind GeoIP, etc.). We connect those entites using several relationships (Co-occurrence, Related Domains, Domain-IP mapping, Registration etc.)

In other words, all this agglomerated data can be seen as a giant graph connecting dots of information. The miner script is a useful tool to extract parts of this graph ("subgraphs"). It digs inside the whole data network from given entry points using a certain mining profile. You can define as many entry points as you want from the command line and the mining profile is defined in a JSON file inside the "profiles" folder. If no profile is defined, it will fall back to the default one.

Once the miner has finished running, the output is a graph dataset stored in the JSON format. You can define the name of the resulting file with the --output argument and this file can be analyzed and loaded with various graph analysis softwares (ex: OpenGraphiti).

Entry points

You can start from any domain, IP, email, ASN or binary hash. Use the --domain, --ip, --email, --asn and --hash arguments if you have only one (Or only one of each). You can use the arguments --domains, --ips, --emails, --asns and --hashes if you need to pass a list contained in a file. The file needs to have only one entry per line.

Examples:

Starts digging from test.com

$ ./miner.py --domain test.com

Starts digging from domain test.com, ip 8.8.8.8 and asn 1234.

$ ./miner.py --domain test.com --ip 8.8.8.8 --asn 1234

Starts digging from all domains located in 'domains.txt', saves the result in 'result.json' and sets the title of the dataset.

$ ./miner.py --domains domains.txt --output result.json --title "Infected Domains"

Mining Profiles

In reality, the data mining process is nothing more than a customizable Breadth First Traversal. Long story short, here is what it does :

The mining profiles help you customize a couple of things :

Different mining profiles will give you different results. Usually, a certain profile corresponds to a certain use case. For example, the "default.json" profile parses every type of node, edges and attributes but select only a bunch of neighbors at every iteration and is limited to a small depth. This is only intended to give you a relatively small dataset for an overview of a certain node neighborhood and a quick understanding of the various types of data that we collect.

Please take a look at "profiles/default.json" for concrete examples.
