Recon
Recon is a target reconnaissance framework powered by knowledge graphs. Using knowledge graphs instead of flat table representation is easier to find the relationships between different types of information, which comes quite handy in many situations. Knowledge graphs algorithms also help with diffing, searching, finding the shortest path, and many other helpful tasks to aid information discovery and intelligence gathering.

NB: Recon is the result of an almost direct copy of SecApps' excellent Recon tool.
Quickstart
This tool is meant to be used as part of Pown.js but it can be invoked separately as an independent tool.
Install Pown first as usual:
$ npm install -g pown@latestInstall recon:
$ pown modules install @pown/reconInvoke directly from Pown:
$ pown reconStandalone Use
Install this module locally from the root of your project:
$ npm install @pown/recon --saveOnce done, invoke pown cli:
$ POWN_ROOT=. ./node_modules/.bin/pown-cli reconYou can also use the global pown to invoke the tool locally:
$ POWN_ROOT=. pown reconLibrary Use
The module is also a library. Check out the code and examples for idea how to use. Documentation is coming soon.

Preview
Generated graphs can be previewed in SecApps Recon for convenience, which this tool is based on. You can access SecApps Recon from your browser but you can also invoke it from the command line.
First you need @pown/apps installed:
$ pown modules install @pown/appsThis will install the optional apps command package.
Generate your graph using the write options:
$ pown recon transform auto -w path/to/file.network --node-type brand targetOnce the recon is complete, open the graph for preview in SecApps Recon:
$ pown apps recon < path/to/file.networkScripting
Pown recon is designed to be scripted either via your favorite shell environment, Pown Script, Pown Engine Templates and JavaScript. Scripts benefit from preserved context between each command execution. This means that you can build a graph without then need to save and restore into intermediate files.
Using your favourite editor create a file called example.pown with the following contents:
echo This is script
recon add --node-type brand target
recon t autoExecute the script from pown:
$ pown script path/to/example.pownFor more information, see the ./examples for more ideas how to use scripts.
Selectors
Some commands expect graph selectors. The rest of the documentation is copy of cytoscape.js selectors manual with some minor differences.
A selector functions similar to a CSS selector on DOM elements, but selectors in Recon instead work on collections of graph elements. This mechanism is provided by the powerful cytoscape.js.
The selectors can be combined together to make powerful queries, for example:
pown select 'node[weight >= 50][height < 180]'
Selectors can be joined together (effectively creating a logical OR) with commas:
pown select 'node#j, edge[source = "j"]'
It is important to note that strings need to be enclosed by quotation marks:
pown select 'node[type = "domain"]'
Note that metacharacters ( ^ $ \ / ( ) | ? + * [ ] { } , . ) need to be escaped:
pown select '#some\$funky\@id'
Group, class, & ID
node,edge, or*(group selector) Matches elements based on group (node for nodes, edge for edges, * for all)..classNameMatches elements that have the specified class (e.g. use .foo for a class named "foo").- The
#idMatches element with the matching ID (e.g.#foois the same as[id = 'foo'])
Data
[name]Matches elements if they have the specified data attribute defined, i.e. not undefined (e.g.[foo]for an attribute named “foo”). Here, null is considered a defined value.[^name]Matches elements if the specified data attribute is not defined, i.e. undefined (e.g[^foo]). Here, null is considered a defined value.[?name]Matches elements if the specified data attribute is a truthy value (e.g.[?foo]).[!name]Matches elements if the specified data attribute is a falsey value (e.g.[!foo]).[name = value]Matches elements if their data attribute matches a specified value (e.g.[foo = 'bar']or[num = 2]).[name != value]Matches elements if their data attribute doesn’t match a specified value (e.g.[foo != 'bar']or[num != 2]).[name > value]Matches elements if their data attribute is greater than a specified value (e.g.[foo > 'bar']or[num > 2]).[name >= value]Matches elements if their data attribute is greater than or equal to a specified value (e.g.[foo >= 'bar']or[num >= 2]).[name < value]Matches elements if their data attribute is less than a specified value (e.g.[foo < 'bar']or[num < 2]).[name <= value]Matches elements if their data attribute is less than or equal to a specified value (e.g.[foo <= 'bar']or[num <= 2]).[name *= value]Matches elements if their data attribute contains the specified value as a substring (e.g.[foo *= 'bar']).[name ^= value]Matches elements if their data attribute starts with the specified value (e.g.[foo ^= 'bar']).[name $= value]Matches elements if their data attribute ends with the specified value (e.g.[foo $= 'bar']).@(data attribute operator modifier) Prepended to an operator so that is case insensitive (e.g.[foo @$= 'ar'],[foo @>= 'a'],[foo @= 'bar'])!(data attribute operator modifier) Prepended to an operator so that it is negated (e.g.[foo !$= 'ar'],[foo !>= 'a'])[[]](metadata brackets) Use double square brackets in place of square ones to match against metadata instead of data (e.g.[[degree > 2]]matches elements of degree greater than 2). The properties that are supported includedegree,indegree, andoutdegree.
Compound nodes
>(child selector) Matches direct children of the parent node (e.g.node > node).node node).$(subject selector) Sets the subject of the selector (e.g.$node > nodeto select the parent nodes instead of the children).
Traversals
A complex type of selection is known as traversal.
Transforms
Here are some of the transforms available in Recon. Additional transforms are available in optional pown modules.
- GitHub Search of Repos, Gists and Members (via @pown/github)
- Bitbucket Search of Repos, Snippets and Members
- CloudFlare 1.1.1.1 DNS API

- Gravatar URLs
- Hacker Target Reverse IP Lookup
- PKS Lookup
- Bufferover.run
- Urlscan
- Threatcrowd
- Wappalyzer
- Riddler

Tutorial
To demonstrate the power of Recon and graph-based OSINT (Open Source Intelligence), let's have a look at the following trivial example.
Let's start by querying everyone who is a member of Google's engineering team and contributes to their GitHub account.
pown recon t -w google.network ghlm googleThis command will generate a table similar to this:
github:member

You just created your first network!
The representation is tabular for convenience but underneath we've got a model which consists of nodes connected by edges.
If you are wondering what that looks like you can use SecApps Recon. The command line does not have the necessary level of interactivity to present the complexity of graphs.
The -w google.network command line option exported the network to a file. You can load the file directly into SecApps Recon with the file open feature. The result will look like this:
Now imagine that we want to query what repositories these Google engineers are working on. This is easy. First, we need to select the nodes in the graph and then transform them with the "GitHub List Repositories" transformation. This is how we do it from the command line:
pown recon t ghlr -r google.network -w google2.nework -s 'node[type="github:member"]'If you don't hit GitHub API rate limits, you will be presented with this:
github:repo

Since now we have two files google.network and google2.network you might be wondering what is the difference between them. Well, we have a tool for doing just that.
pown recon diff google.network google2.networkNow we know! This feature is quite useful if you are building large recon maps and you would like to know what are the key differences. Imagine your cron job performs the same recon every day and you would like to know if something new just appeared which might be worth exploring further. Hello, bug bounty hunters!
