Default guest password for SMB (Samba - port 445) - menorewiskor - Nov 21, 2023

Hey guys!

What is the default guest username/password for Samba shares?

I mean the ones with "authentication: enabled" parameter: https://www.shodan.io/search?query=%22Authentication%3A+disabled%22+port%3A445

Any help would be appreciated guys!

I'm not too familiar with Samba, but I can see that the Samba equivalent of anonymous login for SMB is the 'nobody' guest user. If you're prompted for a username and password, then you cannot login as a guest. I believe that guest login would be the same as "authentication: disabled."

If you were expecting anonymous login to be enabled on every server, well, you should think about that.

What about default admin user/pass?

Default for most FTPs is admin:admin - what about Samba?

As I said, there is no default user and password for Samba. You just connect anonymously.
