Run the plugin with using a state file for the target and updating it useful for running multiple plugins on the target :. This page has been produced using Nessus Professional Table Of Contents.
As name suggests, it is used enumerate all users on remote Windows system using 2 different techniques. More can be read about the differences here. We can run all SMB enumeration scripts in on go by following command. By design, nmap comes with various scripts that can be used to detect various vulnerabilities or CVEs. All these vulnerabilities can be detected using single nmap command. In particular, to SMB, because of it scripting engine i.
NSE nmap can be used to retrieve a great deal of information from remote host. Not just retrieving information from the remote host, it has few scripts that can check on runtime that if any particular service is vulnerable to preconfigured CVEs or not. It comes really handy when scanning multiple hosts on large scale.
SMBmap is go-to tool for every penetration tester or ethical hacker when it comes to enumerating SMB. While it comes pre-installed in Kali Linux it can be installed from here. It is one for all tool and does pretty much everything in terms of enumeration from listing shared drives, permissions to executing remote commands. As you have already guessed, this command will be used for Recursive listing of any folders over SMB.
If we want to map whole SMB port in every aspect, then SMBmap is the only tool that every security practitioner will recommend. It has plethora of commands to query which cannot be discussed in this article alone. We will be going through only basic commands here.
Once we are connected to the remote MS-RPC service either through null session or through, supplied credentials then we can run various command to MS-RPC to retrieve information from remote host. If access to those functions is denied, a list of common share names are checked.
Even if NetShareEnumAll is restricted, attempting to connect to a share will always reveal its existence. So, if NetShareEnumAll fails, a pre-generated list of shares, based on a large test network, are used. If any of those succeed, they are recorded. Here, we can see that we have the shares listed although the Access is Denied the existence of the share is confirmed. Displays a list of domains, computers, or resources that are being shared by the specified computer.
Used without parameters, net view displays a list of computers in your current domain. This time we are on the Windows machine. Then we changed the command by adding the share and we are able to read the contents of that share.
Now using the copy command, we can download the file from share. It requires the IP Address of the target server or machine followed by the set of credentials that can be used to access the share. CrackMapExec a. CrackMapExec can Map the network hosts, Generate Relay List, enumerate shares and access, enumerate active sessions, enumerate disks, enumerate logged on users, enumerate domain users, Enumerate Users by bruteforcing RID, enumerate domain groups, Enumerate local groups etc.
Here, we can see different shares and the permissions that are allowed on that particular share. It has undergone several stages of development and stability. We will be using it to enumerate the users on the SMB shares using the option of netshareenum as shown in the image below. We enumerate a SMB server in order to compromise we need to enumerate and find possible vulnerabilities that can be used to exploit the server. In order to do this in an optimized method, we can perform a Vulnerability Scanning.
There might be multiple tools to perform this kind of Scanning but here we will be focusing on this NSE script. Nmap in past used to have a script by the name of smb-check-vulns. It used to scan the target server for the various vulnerabilities such as:. Then the script was divided into single vulnerability checks that can run individually such as smb-vuln-ms In a Windows environment, each user is assigned a unique identifier called Security ID or SID, which is used to control access to various resources like Files, Registry keys, network shares etc.
Knowing what users exist on a system can greatly speed up any further brute-force logon attempts later on. Here, we can see that through enumerating SMB we have extracted two users: raj and aart. A Security Identifier SID is a unique value of variable length that is used to identify a user account.
Lookupsid script can enumerate both local and domain users. There is a Metasploit module too for this attack. If you are planning on injecting a target server with a golden or a silver ticket then one of the things that are required is the SID of the user. Contributors to Wikimedia projects. McNab, Chris.
