The working of the D-TECT tool is pretty simple, as this is an automated tool you just need to select the modules from the list which appears after running the d-tect.py file. There are various options such as Subdomain Scanner, Port Scanner, WordPress Scanner, etc. You simply need to select the option and provide the target domain URL like (geeksforgeeks.org), after this the tool gathers the information about the target and displays the results in a sophisticated manner onto the terminal itself.
