Solution of Port7

Find the hidden service on the kenobi.hackingarena.com server in the port range 20000-25000 and obtain the flag!

To obtain the flag, we have to use the nmap function. The exact command is nmap -sT -p20000-25000 kenobi.hackingarena.no to list the services. We can see there is an unknown service at port 22389.



We have to use the telnet command to investigate further, telnet kenobi.hackingarena.no 22389. We are now connected to port 22389 and we are asked to answer a question.



To get the flag, we have to select answer 4 as we used a port scanner to catch the flag.
