Is it possible to hack a SSID without actually having to sniff or send deauth frames to a host?

If the network is WPA2 as you sais in comments, this is what you can do:

• You didn't specify if there is WPS enabled or not. So check that using wash (included on reaver package) or using --wps on airodump-ng. Then if enable you can try Pixie Dust attack (very fast but only affecting some Access Points, maybe you could be lucky). Also you can try bruteforce on PIN or an attack based on a PIN database.

• Another way to hack it is getting a Handshake and then cracking it offline. To do that, you must be "listening" with airodump-ng while a legitimate client connect to the network. It doesn't matter if the SSID is hidden. You'll get the handshake anyway and you'll crack it offline based on BSSID. To obtain it, the common method is using DoS deauthenticating client but your question said "without send deauth frames". So if you want the Handshake without DoS you only can wait, wait and wait... until a client connect to get it. You sais there is no clients connected to the network. Maybe you can only set the "listening" and wait for days... Once you have the Handshake captured file you can crack it without fear of being detected or whatever, is an offline proccess. You can use aircrack or hashcat tools (or maybe other).

• Another possibility is to create a Rogue AP Evil Twin with a captive portal hoping the victim confuse the network and put his/her wireless password on your trap. This attack requires a little bit of "social engineering" and a victim without any knowledge about networking (but believe me sometimes it works!). Is usual again to perform DoS to the legitimate network to force them to investigate and maybe they can make click on your fake network. Again without sending "deauth frames" is very very difficult to be successful with this kind of attack.

Of couse you can perform all of these actions with your MAC spoofed to be pretty sure of you are not being detected.

I'll recommend to you a tool what can do ALL of these attacks: airgeddon

Hope it helps!
