During the reconnaissance phase, an attacker searches for any information about his target to create a profile that will later help him to identify possible ways to get in an organization. InfoHound performs passive analysis techniques (which do not interact directly with the target) using OSINT to extract a large amount of data given a web domain name. This tool will retrieve emails, people, files, subdomains, usernames and urls that will be later analyzed to extract even more valuable information.
Infohound architecture
Installation
git clone https://github.com/xampla/InfoHound.git
cd InfoHound/infohound
mv infohound_config.sample.py infohound_config.py
cd ..
docker-compose up -d
You must add API Keys inside infohound_config.py file
Default modules
InfoHound has 2 different types of modules, those which retreives data and those which analyse it to extract more relevant information.
Retrievval modules
| Name | Description |
|---|---|
| Get Whois Info | Get relevant information from Whois register. |
| Get DNS Records | This task queries the DNS. |
| Get Subdomains | This task uses Alienvault OTX API, CRT.sh, and HackerTarget as data sources to discover cached subdomains. |
| Get Subdomains From URLs | Once some tasks have been performed, the URLs table will have a lot of entries. This task will check all the URLs to find new subdomains. |
| Get URLs | It searches all URLs cached by Wayback Machine and saves them into the database. This will later help to discover other data entities like files or subdomains. |
| Get Files from URLs | It loops through the URLs database table to find files and store them in the Files database table for later analysis. The files that will be retrieved are: doc, docx, ppt, pptx, pps, ppsx, xls, xlsx, odt, ods, odg, odp, sxw, sxc, sxi, pdf, wpd, svg, indd, rdp, ica, zip, rar |
| Find Email | It looks for emails using queries to Google and Bing. |
| Find People from Emails | Once some emails have been found, it can be useful to discover the person behind them. Also, it finds usernames from those people. |
| Find Emails From URLs | Sometimes, the discovered URLs can contain sensitive information. This task retrieves all the emails from URL paths. |
| Execute Dorks | It will execute the dorks defined in the dorks folder. Remember to group the dorks by categories (filename) to understand their objectives. |
| Find Emails From Dorks | By default, InfoHound has some dorks defined to discover emails. This task will look for them in the results obtained from dork execution. |
Analysis
| Name | Description |
|---|---|
| Check Subdomains Take-Over | It performs some checks to determine if a subdomain can be taken over. |
| Check If Domain Can Be Spoofed | It checks if a domain, from the emails InfoHound has discovered, can be spoofed. This could be used by attackers to impersonate a person and send emails as him/her. |
| Get Profiles From Usernames | This task uses the discovered usernames from each person to find profiles from services or social networks where that username exists. This is performed using the Maigret tool. It is worth noting that although a profile with the same username is found, it does not necessarily mean it belongs to the person being analyzed. |
| Download All Files | Once files have been stored in the Files database table, this task will download them in the "download_files" folder. |
| Get Metadata | Using exiftool, this task will extract all the metadata from the downloaded files and save it to the database. |
| Get Emails From Metadata | As some metadata can contain emails, this task will retrieve all of them and save them to the database. |
| Get Emails From Files Content | Usually, emails can be included in corporate files, so this task will retrieve all the emails from the downloaded files' content. |
| Find Registered Services using Emails | It is possible to find services or social networks where an email has been used to create an account. This task will check if an email InfoHound has discovered has an account in Twitter, Adobe, Facebook, Imgur, Mewe, Parler, Rumble, Snapchat, Wordpress, and/or Duolingo. |
| Check Breach | This task checks Firefox Monitor service to see if an email has been found in a data breach. Although it is a free service, it has a limitation of 10 queries per day. If Leak-Lookup API key is set, it also checks it. |
Custom modules
InfoHound lets you create custom modules, you just need to add your script inside infohoudn/tool/custom_modules. One custome module has been added as an example which uses Holehe tool to check if the emails previously are attached to an account on sites like Twitter, Instagram, Imgur and more than 120 others.
