If the ldap-brute script has been selected and it found a valid account, this account will be used. If not anonymous bind will be used as a last attempt. If set, overrides the number of objects returned by the script default The value -1 removes the limit completely. If set, specifies a quick filter. The library does not support parsing real LDAP filters.

If no value is specified it defaults to all. If set, the search will include only the attributes specified. For a single attribute a string value can be used, if multiple attributes need to be supplied a table should be used instead.

When used with the 'custom' qfilter, this parameter works in conjunction with ldap. If set, the script will save the output to a file beginning with the specified path and name. The file suffix of. CSV as well as the hostname and port will automatically be added based on the output type selected.

If set, the script will use it as a base for the search. By default the defaultNamingContext is retrieved and used. If no defaultNamingContext is available the script iterates over the available namingContexts. Script Arguments ldap. If no defaultNamingContext is available the script iterates over the available namingContexts Example Usage nmap -p --script ldap-search --script-args 'ldap.In your information gathering stage, this can provide you with some insight as to some of the services that are running on the remote system.

We can see that running the scanner without credentials does not return a great deal of information. The smb2 scanner module simply scans the remote hosts and determines if they support the SMB2 protocol.

As you can see, since this is an un-credentialed scan, access is denied a most of the systems that are probed.

Passing user credentials to the scanner will produce much different results. We can see that running the scan without credentials, only the Linux Samba service coughs up a listing of users.

Passing a valid set of credentials to the scanner will enumerate the users on our other targets. This is an example of why it pays to run a scanner in different configurations. If you have a database plugin loaded, successful logins will be stored in it for future reference and usage.

You can clearly see that this module has many more options that other auxiliary modules and is quite versatile.

We will first run a scan using the Administrator credentials we found. There are many more options available that you should experiment with to fully familiarize yourself with this extremely valuable module. Knowing what users exist on a system can greatly speed up any further brute-force logon attempts later on. By way of comparison, we will also run the scan using a known set of user credentials to see the difference in output.

You will notice with credentialed scanning, that you get, as always, a great deal more interesting output, including accounts you likely never knew existed. Running this same scan with a set of credentials will return some different, and perhaps unexpected, results. Contrary to many other cases, a credentialed scan in this case does not necessarily give better results.

If the credentials are not valid on a particular system, you will not get any result back from the scan. The connection was refused by the remote host Proxies no A proxy chain of format type:host:port[,type:host:port][Attempts to brute-force LDAP authentication.

By default it uses the built-in username and password lists.

In order to use your own lists use the userdb and passdb script arguments. This script does not make any attempt to prevent account lockout! If the number of passwords in the dictionary exceed the amount of allowed tries, accounts will be locked out. This usually happens very quickly. LDAP on Windows allows authentication using a simple user name rather than using the fully distinguished name.

If the script receives an error indicating that the username does not exist it simply stops guessing passwords for this account and moves on to the next. The script attempts to authenticate with the username only if no LDAP base is specified. The benefit of authenticating this way is that the LDAP path of each account does not need to be known in advance as it's looked up by the server.

This technique will only find a match if the account Display Name matches the username being attempted. For example if the ldap.

When the UPN is known using this setting should provide more reliable results against domains that have been organized into various OUs or child domains. If both ldap. See the AD discussion in the description. DO NOT use ldap. If set, the script will save the output to a file beginning with the specified path and name. The file suffix will automatically be added based on the output type selected. If set, the script will save the passwords in the specified format. The current formats are CSV, verbose and plain.

In both verbose and plain records are separated by colons. The difference between the two is that verbose includes the credential state. When ldap. If set, the script will use it as a base for the password guessing attempts.

Metasploit Module of the Month – enum_ad_computers

Insight Products. Helpful Links. Description This module will enumerate computers in the default AD directory. Penetration testing software for offensive security teams.Summer has officially ended and Autumn is setting in.

Leveraging the abilities of the two allows an attacker to expedite information gathering following compromise. Administrative privileges are not required to execute LDAP queries. Situational awareness in a Windows domain is essential to escalation. For example, enumerating all the domain users is a great way to cast a wider net when phishing and social engineering are in scope:.

Armed with these commands, why resort to LDAP queries? LDAP Lightweight Directory Access Protocol queries, though arguably more complicated, are also more flexible, and can be tailored to return the specific pieces of information that penetration testers seek. Not surprisingly, a metasploit module already exists to harness the LDAP queries.

Take the default settings as an example:. Running the query with these parameters will search for the host name, the distinguished name a field that displays the unique object within its hierarchical AD contexta description if the administrator was so kind as to include oneand the self-explanatory operating system and its service pack. In the tiny domain used in this post, it produces the following output:. One of the beautiful things about executing these queries through metasploit is the ability to utilize its database.

If the attacker chooses to focus on users as opposed to or in addition to computers, he or she simply has to change the object category and select some more appropriate fields:. If the description and mail fields within AD are both filled out, this sort of query has the potential to quickly expand the social engineering attack surface. The filters and fields can be refined to a much higher degree of granularity than in the examples above.

By combining these detailed queries into a logical sequence with a simple resource script that also sets the appropriate fields, an attacker can maximize the efficiency of the information gathering phase:. Look over the range of possible LDAP queries and consider how they can elicit the information necessary to plan and execute the next stages of an attack. Happy hunting and happy Fall.
