Just-Metadata – Intel Gathering and Analysis of IP Metadata

Just-Metadata is a tool that can be used to gather intelligence
information passively about a large number of IP addresses, and attempt
to extrapolate relationships that might not otherwise be seen.
Just-Metadata has “gather” modules which are used to gather metadata
about IPs loaded into the framework across multiple resources on the
internet. Just-Metadata also has “analysis” modules. These are used to
analyze the data loaded Just-Metadata and perform various operations
that can identify potential relationships between the loaded systems.

Just-Metadata will allow you to quickly find the Top “X” number of
states, cities, timezones, etc. that the loaded IP addresses are located
in. It will allow you to search for IP addresses by country. You can
search all IPs to find which ones are used in callbacks as identified by
VirusTotal. Want to see if any IPs loaded have been documented as
taking part of attacks via the Animus Project, Just-Metadata can do it.

Additionally, it is easy to create new analysis modules to let people
find other relationships between IPs loaded based on the available
data. New intel gathering modules can be easily added in just as

Ideally, you should be able to run the setup script, and it will install everything you need.
For the Shodan information gathering module, YOU WILL NEED a Shodan
API key. This costs like $9 bucks, come on now, it’s worth it :).


As of now, Just metadata is designed to read in a single text file
containing IPs, each on their own new line. Create this file from any
source (C2 callback IPs, web server logs, etc.). Once you have this
file, start Just-Metadata by calling it:



help – Once in the framework, to see a listing of available commands and a description of what they do, type the “help” command.

load <filename> – The load command takes an
extra parameter, the file name that you (the user) want Just-Metadata to
load IP addresses from. This command will open, and load all IPs
within the file to the framework.
Ex: load ipaddresses.txt

save – The save command can be used to save the
current working state of Just-Metadata. This is helpful in multiple
cases, such as after gathering information about IPs, and wanting to
save the state off to disk to be able to work on them at a later point
in time. Simply typing “save” will result in Just-Metadata saving the
state to disk, and displaying the filename of the saved state.

import <statefile> – The import command can be
used to load a previously saved Just-Metadata state into the framework.
It will load all IPs that were saved, and all information gathered
about the IP addresses. This command will require an extra parameter,
the name of the state file that you want Just-Metadata to load.

Ex: import goodfile.state

list <module type> – The list command can be
used to list the different types of modules loaded into Just-Metadata.
This command will take an extra parameter, either “analysis” or
“gather”. Just-Metadata will display all mofules of the type that the
user requests is listed.

Ex: list analysis
Ex: list gather

gather <gather module name> – The gather
command tells Just-Metadata to run the module specified and gather
information from that source. This can be used to gather geographical
information, Virustotal, whois, and more. It’s all based on the module.
The data gathered will be stored within the framework in memory and
can also be saved to disk with the “save” command.

Ex: gather geoinfo
Ex: gather virustotal

analyze <analysis module name> – The analyze
command tells Metadata to run an analysis module against the data loaded
into the framework. These modules can be used to find IP addresses
that share the same SSH keys or SSL Public Key certificates, or
certificate chains. They can also be used to find IP addresses used in
the same callbacks by malicious executables.

ip_info <IP Address> – This command is used to
dump all information about a specific IP address. This is currently
being used after having run analysis modules. For example, after
identifying IP addresses that share the same SSH keys, I can dump all
information about those IPs. I will see if they have been used by
malware, where they are located, etc.

export – The export command will have Just-Metadata
dump all information that’s been gathered about all IP addresses
currently loaded into the framework to CSV.
