The extensive range of options provided by Photon lets you crawl the web exactly the way you want, which is a cool thing on its own. However, the features of Photon that make it awesome are follows:
Data Extraction
Photon extracts the following data while crawling by default:
URLs (in-scope & out-of-scope)
URLs with parameters (example.com/gallery.php?id=2)
Intel (emails, social media accounts, amazon buckets etc.)
Files (pdf, png, xml etc.)
JavaScript files & Endpoints present in them
Strings based on custom regex pattern
The extracted information is saved in an organized manner.
Intelligent Multithreading
Here's a secret, most of the tools floating on the internet aren't properly multi-threaded even if they are supposed to. They either supply a list of items to threads which results in multiple threads accessing the same item or they simply put a thread lock and end up rendering multi-threading useless. But Photon is different or should I say "genius"? Take a look at this and decide yourself.
Ninja Mode
In Ninja Mode, 3 online services are used to make requests to the target on your behalf. So basically, now you have 4 clients making requests to the same server simultaneously which gives you a speed boost if you have a slow connection, minimizes the risk of connection reset as well as delays requests from a single client. Here's a comparison generated by Quark where the lines represent threads:
Plugins
Photon's capabilites can be further extended by using plugins.
Available plugins:
dnsdumpster: Generates an image containing the DNS data of the target domain.
Exporter: Plugin to export results in JSON, support for more formats is being worked on.
Plugins in active development:
Quark: A plugin to plot a graph making it easier to inspect relationships between different webpages using Quark.
XSStrike: Modular & targeted version of XSStrike to be used with Photon.
dnsdumpster: A new version of the plugin is in development which will save the DNS data in a nicely formatted HTML file.
