smbmap is a command-line tool used for SMB (Server Message Block) enumeration, which is the process of discovering information about SMB shares on a remote server. SMB is a network protocol used for sharing files, printers, and other resources between computers on a network.
With smbmap, you can scan a remote server for SMB shares, enumerate the contents of those shares, and identify the access level required to read or write to those shares. The tool supports authentication and encryption options for secure communication with the server.
smbmap is particularly useful for security professionals and network administrators who need to assess the security of SMB shares on a network. It can be used to identify unsecured shares, determine the access level required to read or write to a share, and check if the shares are being properly audited and secured.
smbmap can also be used to automate the enumeration process by integrating it into scripts and automation tasks. This can save time and effort when performing regular security assessments or network scans.
If you encounter the below error while running the command smbmap:
smbmap: command not found
you may try installing the below package as per your choice of distribution:
| Distribution | Command |
|---|---|
| Debian | apt-get install smbmap |
| Ubuntu | apt-get install smbmap |
| Kali Linux | apt-get install smbmap |
smbmap Command Examples
1. Enumerate hosts with NULL sessions enabled and open shares:
# smbmap --host-file path/to/file
2. Enumerate hosts and check SMB file permissions:
# smbmap --host-file path/to/file -u username -p password -q
3. Connect to an ip or hostname through smb using a username and password:
# smbmap -u username -p password -d domain -H ip_or_hostname
4. Locate and download files [R]ecursively up to N levels depth, searching for filename pattern (regex), and excluding certain shares:
# smbmap --host-file path/to/file -u username -p password -q -R --depth number --exclude sharename -A filepattern
5. Upload file through smb using username and password:
# smbmap -u username -p password -d domain -H ip_or_hostname --upload path/to/file '/share_name/remote_filename'
Summary
In summary, smbmap is a powerful tool for SMB enumeration that can be used to identify and assess the security of SMB shares on a network. Its ability to scan for shares, enumerate their contents, and identify access levels required make it a popular choice for security professionals and network administrators who need to assess the security of their network.
