SMB Version Detection



Fingerprint and display version information about SMB servers. Protocol information and host operating system (if available) will be reported. Host operating system detection requires the remote server to support version 1 of the SMB protocol. Compression and encryption capability negotiation is only present in version 3.1.1.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/scanner/smb/smb_version
msf auxiliary(smb_version) > show actions
msf auxiliary(smb_version) > set ACTION < action-name >
msf auxiliary(smb_version) > show options
    ...show and set options...
msf auxiliary(smb_version) > run 

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
