SMB:</p><ul><li>139/TCP - Initially Microsoft implemented SMB on top of their existing NetBIOS network architecture, which allowed for Windows computers to communicate across the same network<li>445/TCP - Newer versions of SMB use this port, were NetBIOS is not used.</ul><p>Other terminology to be aware of:</p><ul><li>SMB - Server Message Blocks<li>CIFS - Common Internet File System<li>Samba - A free software re-implementation of SMB, which is frequently found on unix-like systems</ul><p>Metasploit has support for multiple SMB modules, including:</p><ul><li>Version enumeration<li>Verifying/bruteforcing credentials<li>Capture modules<li>Relay modules<li>File transfer<li>Exploit modules</ul><p>There are more modules than listed here, for the full list of modules
