Inthis article, we will learn about SAM. We will learn about the passwords and how they are stored in the SAM. We will also focus on the NTLM Authentication. At last, we will be using a bunch of different tools to extract those credentials from SAM.

SAM is short for the Security Account Manager which manages all the user accounts and their passwords. It acts as a database. All the passwords are hashed and then stored SAM. It is the responsibility of LSA (Local Security Authority) to verify user login by matching the passwords with the database maintained in SAM. SAM starts running in the background as soon as the Windows boots up. SAM is found in C:\Windows\System32\config and passwords that are hashed and saved in SAM can found in the registry, just open the Registry Editor and navigate yourself to HKEY_LOCAL_MACHINE\SAM.

When any password is stored in Windows, NTLM starts working by encrypting the password and storing the hash of the said password while it disposes of the actual password. And it further sends the username to the server, then the server creates a 16-byte random numeric string, namely nonce and sends it to the client. Now, the client will encrypt the nonce using the hash string of the password and send the result back to the server. This process is called a response. These three components (nonce, username, and response) will be sent to Domain Controller. The Domain Controller will recover the password using hash from the Security Account Manager (SAM) database. Furthermore, the domain controller will check the nonce and response in case they match, Authentication turns out to be successful.

This tool is developed by Tarasco and you can download it from here. This tool extracts the SAM file from the system and dumps its credentials. To execute this tool just run the following command in command prompt after downloading:

The method of Metasploit involves PowerShell. After getting the meterpreter session, access windows PowerShell by using the command load PowerShell. And then use the following set of commands to run the Invoke-PowerDump.ps1 script.

Again, via meterpreter, access the windows PowerShell using the command load PowerShell. And just like in the previous method, use the following commands to execute the scripts to retrieve the passwords.

There is a good enough method to dump the hashes of SAM file using mimikatz. The method is pretty easy and best suited for internal penetration testing. In one of our previous article, we have covered mimikatz, read that article click here. So in this method, we will use token::elevate command. This command is responsible for allowing mimikatz to access the SAM file in order to dump hashes. Now, to use this method use the following set of commands:

The next method that Metasploit offers are by firing up the mimikatz module. To load mimikatz, use the load kiwi command and then use the following command to dump the whole SAM file using mimikatz.

LaZage is an amazing tool for dumping all kinds of passwords. We have dedicatedly covered LaZagne in our previous article. To visit the said article, click here. Now, to dump SAM hashes with LaZagne, just use the following command:

CrackMapExec is a really sleek tool that can be installed with a simple apt install and it runs very swiftly. Using CrackMapExec we can dump the hashes in the SAM very quicly and easily. It requires a bunch of things.

The article focuses on dumping credentials from the windows SAM file. Various methods have been shown using multiple platforms to successfully dump the credentials. To secure yourself you first must learn how a vulnerability can be exploited and to what extent. Therefore, such knowing such methods and what they can do is important.

Adobe is investigating what appears to be the misuse of an Adobe code signing certificate. Adobe has revoked the certificate on October 4 for all software code signed after July 10, 2012 (00:00 GMT). Adobe has issued updates signed using a new digital certificate for all affected products.

The vast majority of Adobe customers will not be impacted by this issue. However, some customers, in particular administrators in managed Windows environments, may need to take certain action. To determine whether you or your organization are impacted, please refer to the support page on the Adobe website.

Adobe is investigating what appears to be the misuse of an Adobe code signing certificate. Adobe is aware at this time of two malicious utilities from a single source that appeared to be digitally signed using a valid Adobe code-signing certificate.

The first malicious utility is pwdump7 v7.1. This utility extracts password hashes from the Windows OS and is sometimes used as a single file that statically links the OpenSSL library libeay.dll. The sample we received included the two files separate and individually signed.

Adobe has shared information about these files with partners in the security community, including participants in the Microsoft Active Protections Program (MAPP) to enable them to quickly develop detection and quarantine methods to protect against the inappropriately signed utilities. For more information related to this issue, please refer to the following blog post.

Adobe has revoked the certificate on October 4 for all software code signed after July 10, 2012 (00:00 GMT). Adobe has issued updates signed using a new digital certificate for all affected products.

Note: The revocation of the certificate affects the Windows platform and three Adobe AIR applications (Adobe Muse and Adobe Story AIR applications as well as Acrobat.com desktop services) that run on both Windows and Macintosh. The revocation does not impact any other Adobe software for Macintosh or other platforms.

It is very common during penetration tests where domain administrator access has been achieved to extract the password hashes of all the domain users for offline cracking and analysis. These hashes are stored in a database file in the domain controller (NTDS.DIT) with some additional information like group memberships and users.

The NTDS.DIT file is constantly in use by the operating system and therefore cannot be copied directly to another location for extraction of information. This file can be found in the following Windows location:

Mimikatz has a feature (dcsync) which utilises the Directory Replication Service (DRS) to retrieve the password hashes from the NTDS.DIT file. This technique eliminates the need to authenticate directly with the domain controller as it can be executed from any system that is part of the domain from the context of domain administrator. Therefore it is the standard technique for red teams as it is less noisy.

PowerShell Empire has two modules which can retrieve domain hashes via the DCSync attack. Both modules needs to be executed from the perspective of domain administrator and they are using Microsoft replication services. These modules rely on the Invoke-Mimikatz PowerShell script in order to execute Mimikatz commands related to DCSync. The following module will extract the domain hashes to a format similar to the output of Metasploit hashdump command.

Nishang is a PowerShell framework which enables red teamers and penetration testers to perform offensive operations against systems. The Copy-VSS script can be used to automatically extract the required files: NTDS.DIT, SAM and SYSTEM. The files will be extracted into the current working directory or into any other folder that will specified.

It is also possible to establish a direct PowerShell session with the command powershell_shell in order to extract the files once the script has been imported to the existing Meterpreter session.

The ntdsutil is a command line tool that is part of the domain controller ecosystem and its purpose is to enable administrators to access and manage the windows Active Directory database. However it can be abused by penetration testers and red teams to take a snapshot of the existing ntds.dit file which can be copied into a new location for offline analysis and extraction of password hashes.

DiskShadow is a Microsoft signed binary which is used to assist administrators with operations related to the Volume Shadow Copy Service (VSS). Originally bohops wrote about this binary in his blog. This binary has two modes interactive and script and therefore a script file can be used that will contain all the necessary commands to automate the process of NTDS.DIT extraction. The script file can contain the following lines in order to create a new volume shadow copy, mount a new drive, execute the copy command and delete the volume shadow copy.

It should be noted that the DiskShadow binary needs to executed from the C:\Windows\System32 path. If it is called from another path the script will not executed correctly.

Sean Metcalf demonstrated in his blog that it is possible to remotely extract the NTDS.DIT and SYSTEM files via WMI. This technique is using the vssadmin binary to create the volume shadow copy.

The volume shadow copy is a Windows command line utility which enables administrators to take backups of computers, volumes and files even if they are in use by the operating system. Volume Shadow Copy is running as a service and requires the filesystem to be formatted as NTFS which all the modern operating systems are by default. From a Windows command prompt executing the following will create a snapshot of the C: drive in order files that are not normally accessible by the user to be copied into another location (local folder, network folder or removable media).

Since all the files in the C: drive have been copied into another location (HarddiskVolumeShadowCopy1) they are not directly used by the operating system and therefore can be accessed and copied into another location. The command copy and will copy the NTDS.DIT and SYSTEM files to a new created folder on the local drive named ShadowCopy.
