Hello, If a backdoor is set to only accept connections from a configured ip address or network, I guess that nmap will found this port as filtered, as your ip address is not allowed to connect. Regards, Alejandro Flores
Can a port scanner not see a port that is opened? The question is: can a backdoor be on a machine, and with nmap -p 1-, for example, you couldn't see it? Thank you, Eduardo
