Automating Open Source Intelligence (OSINT) using Python

Sudhanshu Chauhan (~sudhanshu)




Open Source Intelligence is the art of collecting information which is scattered on publicly available sources. With evolution of social media and digital marketplaces a huge amount of information is constantly generated on the Internet (sometimes even without our conscious consent). This is of great concern for organisations and businesses as chances of confidential data floating in the public domain may seriously harm their business integrity. Similarly from a pentester's perspective it is important to collect as much information as possible about the target before going for the kill.

Based on experience and robust research in this domain, for this talk the speakers have created a tool ( which will help all kind of organisations to identify the threat landscape they expose, without much investment. This tool is simple but an effective solution which is capable of collecting information which is usually missed or ignored, but shouldn’t be.<br><br> <b> During the presentation, we will discuss and demonstrate how we automated the process of OSINT and used the same in our security assessments. Topics covered will include:

<li>Public WhoIs, DNS Records.</li> <li>Domain IP History</li> <li>Website’s technology profiling.</li> <li>Looking for publicly available Vulnerability Information about the target.</li> <li>Enumerating Subdomains and other exposed resources.</li> <li>Harvesting Emails from domain and further profiling users behind these emails.</li> <li>Social Profile Enumeration</li> <li>Fetching information from Hacker Search Engines.</li> <li>Breach Status of target and Email Ids.</li> <li>Extraction of juicy information from Github.</li> <li>Targeted intelligence on username using Geo Location and other information accumulated from Social media. </li>
