Install and use phone info ga, a Python 3 OSINT tool for phone numbers, by cloning from GitHub, installing requirements, and running commands to identify country, time zone, and landlines.
In this course we will be learning about OSINT (reconnaissance) focused for ethical hacking and penetration testing. Int his course we will be building a virtual machine, loading Kali Linux, and leveraging a number of web based tools in order to identify and track our targets. OSINT is a critical skill to understand for any hacker and pentester. As always if you have any questions or issues, always feel free to let me know before, during, and even after the course.
