Solution of Port8

Find the hidden service on the server in the port range 25000-30000 and obtain the flag!

We have to use the command nmap -sT -p25000-30000 We can see there is an unknown service at port 26414.

When we use the telnet command (telnet 26414), it looks like an ftp service is running on the port. The ftp banner contains the flag.
