InfoSec Write-ups – Medium–
Here I will be briefing, how I created my first python tool for grabbing I.P address(IPv4) and detecting OS (Operating System) for user present on same network.
#Only for educational purpose don’t perform any malicious action on the network which you did not own. Strict actions could be taken!
It’s a simple python script comprises various python libraries which I made for college project you can check it out on my GitHub profile. Follow & feel free to add other features. P.S still n00b 😆
#NOTE – It only works for internal i.p address connected on LAN not public i.p address.
1. It inputs a IPv4 address for listening.
2. Then it opens a port for receiving incoming requests on the same IP which acts like a server and logs the i.p address of the visitor.
3. And performs a scan to detect OS for logged i.p and it is recursive can log mutilple ip’s at same time.
4. After step-1 our program begin to listen on given i.p address, if you want to know the i.p of any device or user in LAN just send this i.p to them & upon clicking or visting it, their i.p will be logged and expected OS will be printed.
Now you know the i.p address, operating system of that particular guy or user on the network. Congrats 🎉
