We can use the db_nmap command to run Nmap against our targets and our scan results would than be stored automatically in our database. Lua is programming language supported by NSE. smbclient is a client that can ‘talk’ to an SMB/CIFS server.

Nmap done: 1 IP address (1 host up) scanned in 186.76 seconds Notice how we got more information about a service on the open ports, including the service version. This feature is called Nmap Scripting Engine (NSE). The commit to help smb-ls use smb-enum-shares is here: 4d0e7c9 And the hassles when trying to enumerate shares with might be related to MSRPC: NetShareGetInfo() which is at msrpc.lua. Nmap is able to detect malware and backdoors by running extensive tests on a few popular OS services like on Identd, Proftpd, Vsftpd, IRC, SMB, and SMTP. Oh, what about that exact version info you say? Operations include things like getting files from the server to the local machine, putting files from the local machine to the server, retrieving directory information from …

nmap -v -sV -O -sS -T5 target Prints verbose output, runs stealth syn scan, T5 timing, OS and version detection. NSE gives user the ability to write scripts for test. But at this point, I'm not familiar enough with SMB/CIFS to debug and understand how or why things break. This recipe shows how to obtain system information from SMB with Nmap. Don’t worry, that’s coming up right now thanks to the smb-os-discovery nmap script. I tried to manually add smb-check-vulns.nse by fetching the script source from nmap.org, but that gave me some errors and the script is not running. nmap is version 7.12. I've noticed that smb-check-vulns.nse is not present. As far as I can tell, most other scripts I use are there but I've got an exam coming up and I don't want any bad surprises. This is useful information as it allows us to fingerprint systems without the noise from OS detection scan.

1 Nmap & db_nmap; 2 Port Scanning; 3 SMB Version Scanning; 4 Idle Scanning; Nmap & db_nmap. To speed it up we will only scan the netbios port, as that is all we need for the script to kick in. It offers an interface similar to that of the FTP program. It also has a module to check for popular malware signs inside remote servers and integrates Google’s Safe Browsing and VirusTotal databases as well. PORT STATE SERVICE VERSION 80/tcp open upnp Epson WorkForce 630 printer UPnP (UPnP 1.0; Epson UPnP SDK 1.0) |_http-title: WorkForce 630 Service Info: Device: printer; CPE: … [root@bt ~] # nmap --script smb-os-discovery -p 445 192.168.1.1/24 Nmap scan report for 192.168.1.118 Host is up (0.0035s latency). The information available includes Windows version, build number, NetBIOS computer name, workgroup, and exact system time. Nmap provides script scanning which gives nmap very flexible behavior to get more information and test about the target host. NSE have some vulnerability detection scripts too. This information is very useful if you are looking for vulnerabilities in certain versions of software.
