Here are some cybersecurity tools used to collect data about the hacker. I might add some other tools later as I learn.
The harvester
It collects public information about target domain.


sudo apt install theharvester
restfulHarvest -h
theHarvester -d abc.com -b all
Exiftool
This gets the metadata of the image.

sudo apt install libimage-exiftool-perl
exiftool -ext jpg -r /path/to/dir
searches for jpg files in a directory
exiftool -csv -r /path/to/dir > meta.csv
Exports data to csv format
Photon
This takes all the data from a website and pasts it into a folder.

photon -u abc.com
Sherlock
This cheaks for a username on multiple platforms across the internet.

sudo apt install sherlock
sherlock cyberflow
Shodan
Shodan is a website that is used to access devices connected to the internet like a camera

Hope you learnt something new.
