Very nice work. I successfully got clear text passwords by injecting into LSASS on Windows 2008 R2, however, I had a problem on Windows 7 x64. I launched a local cmd.exe shell as Local System by using PsExec. From there I launched mimikatz. After typing @getLogonPasswords, the data was there but the wdigest passwords were completely garbled text. I guess something went wrong with the injection. I wonder if it has anything to do with ASLR.
Output is : 3b 62 64 00 1f eb c9 91 7d 70 0c b0 4f 13 07 66 7f cf b0 50, your SHA1 ;)mimikatz credentials output routine try to detect if the password is a printable string, if not, it display it in hex.
mimikatz download exe for windows
Or does it mean that I am trying to work with a version of windows such as XP which doesnt natively have the Tkspg, Wdigest or Kerberos TGT functionality and it is the version of Windows that is wrong?
Hello blog readers.i was wondering of there are any traces of passing the ticket?i.e. is there a special windows event or some way to find that being a domain admin that is concerned about his domain security?

Im getting the following error on a Win7 box. It looks like there is no AV/protection as Im even allowed to drop mimikatz on disk without even getting flagged. Any idea how is this error being triggered?Sorry, but I dont have any sysinfo-like output. It was a Win7 workstation with no evident protection. (yes, im system)
Benjamin Delpy originally created Mimikatz as a proof of concept to show Microsoft that its authentication protocols were vulnerable to an attack. Instead, he inadvertently created one of the most widely used and downloaded threat actor tools of the past 20 years.
Mimikatz is an open source malware program used by hackers and penetration testers to gather credentials on Windows computers. Coded by Benjamin Deply in 2007, mimikatz was originally created to be a proof of concept to learn about Microsoft authentication protocol vulnerabilities. However, mimikatz has since become a popularly downloaded hacking tool.
In order to function completely, mimikatz requires administrator or full system controls. A mimikatz attack uses several techniques to find sensitive information such as plaintext passwords, hash, pin codes, and tickets from the memory of a system. The collected credentials can then be used to access unauthorized information or perform lateral movement attacks.
While mimikatz is generally used as an underground and harmful tool, and spreading malware viruses is illegal in most countries, some professionals may still advertise this as a skill they perform within the commercial hacking industry. This is where companies hire white hat hackers to help them search for weaknesses in their own security systems.
There are always new ways to hack a computer using mimikatz, so defenses against it need to be adaptable and updated to stay effective. A mimikatz attack is hard to detect, but it is possible to check whether a machine or account is compromised. It is easier to execute a mimikatz attack in a system with wide access, because it stores several credentials under one access point. For example, a user that runs Windows with a single sign-on (SSO) system.
Mimikatz is an open source Windows utility available for download from GitHub. First developed in 2007 to demonstrate a practical exploit of the Microsoft Windows Local Security Authority Subsystem Service, or LSASS, Mimikatz is capable of dumping account login information, including clear text passwords stored in system memory.
mimikatz -- French for cute cat -- is a post-exploitation tool intended to help attackers -- whether black hat hackers, red team hackers or penetration testers -- to extract login IDs, passwords and authentication tokens from hacked systems in order to elevate privileges and gain greater access to systems on a breached network.
The best place to get Mimikatz is from the Mimikatz GitHub project page, where you can download the Mimikatz source code. Precompiled binaries for Windows are also available from the Mimikatz GitHub page.
If you choose to download the Mimikatz source code, you'll need to compile the code with Microsoft Visual Studio. Downloading any version of Mimikatz, either the source code or the precompiled binaries, can be a challenge, as modern browsers and operating systems classify Mimikatz as dangerous and block users from downloading it. Many endpoint security products -- including Microsoft's own Windows Defender -- will block Mimikatz because the software is often used in attacks.

Mimikatz.exe can extract plain text passwords from Windows memory, password hashes, Kerberos tickets, etc. Also, mimikatz allows you to perform pass-the-hash, pass-the-ticket attacks or generate Golden Kerberos tickets. The mimikatz functionality is also available in the Metasploit Framework.
As you can see, thanks to mimikatz we got NTLM hashes of all active users! The command was successful because the Debug Mode is enabled on this computer, which allows you to set the SeDebugPrivilege flag for the desired process. In this mode, programs can get low-level access to the memory of processes launched on behalf of the system.
To do it, you need the Debugging Tool for Windows (WinDbg), mimikatz itself and a tool to convert .vmem into a memory dump file (in Hyper-V, it can be vm2dmp.exe or MoonSols Windows Memory toolkit for VMWare vmem-files).
In the mimikatz, there are other options for getting passwords and their hashes from memory (WDigest, LM-hash, NTLM-hash, the module for capturing Kerberos tickets). Therefore it is recommended to implement the following security measures for protection:
Wmic /NODE:"[REDACTED]" /USER:"[REDACTED]" /password:[REDACTED] process call create "cmd.exe /c (c:\windows\security\mnl.exe pr::dg sl::lp et -p >c:\windows\security\PList.txt) >> c:\windows\temp\temp.txt"
If you ever tried downloading a Mimikatz release with AV enabled, you noticed that this is not possible because every single release is flagged. And this is completely plausible, because today attackers use Mimikatz and many other open Source projects in real world incidents. Im pretty sure that Mimikatz is the most used software to extract credentials from the lsass process or the sam database, perform pass the hash attacks, decrypt DPAPI secrets and a lot more. A nice but by far not full overview of the features can be found at ADSecurity.org or in the Mimikatz Wiki. 2ff7e9595c
