Hello, I'm new to CTF, and I invaded a server with the exploit vsftdp 2.3.4 (backdoor) through Metasploit, how do I get my invasion scoring?
There are three ways to score:
Take challenges from Security Shepherd 
Take challenges from your dashboard and fulfill "REPORT VULNERABILITY"
Hack into any servers from 10.194.0.1/24 IP range and fulfill "REPORT VULNERABILITY"
You should read Vulnerability Reporting | Rules and Guidelines before sending any reports.
