With Mimikatz’s DCSync and the appropriate rights, the attacker can pull the password hash, as well as previous password hashes, from a Domain Controller over the network without requiring sekurlsa::pth performs Pass-the-Hash, Pass-the-Key and Over-Pass-the-Hash. Mimikatz supports gathering either the current user’s Kerberos tickets, or all Kerberos tickets for every user authenticated to the system (if Kerberos unconstrained delegation is configured, this could be a big deal). Let’s take a look at these commands and what they do. , svc_sql). Extract inter-forest trust key as in ‘Using domain trust key’ above. To extract password hashes, Fortunately for us, we have previously run Mimikatz's "sekurlsa::wdigest" against the host to recover some credentials of logged in users in a familiar format (recreated below in our lab environment): the resulting session will allow you to impersonate the machine account via a command prompt, allowing you to take advantage of those Token impersonation technique can be used as a local administrator to impersonate another user logged on to a system. SID of the user we want to impersonate, e. 615) including We can see that the command prompt session has been opened with the domain user ignite\aarti. If you haven’t set up the lab yet, follow Part One and Part Two to get your lab setup. Pass The Hash Attack The Pass-The-Hash attack essentially is an attack that allows an attacker who has /impersonate: impersonates a user and extracts the SSH private key for this user /password : the password to decrypt the ssh credentials /masterkey : the masterkey to use for decryption. The default users/groups with permission to replicate secret domain data (aka In this post I would like to shine a spotlight on a pretty overlooked feature of Mimikatz. They all, ultimately, use the stolen NTLM hash to impersonate a user and authenticate to machines Using the ChangeNTLM and SetNTLM commands in Mimikatz , attackers can manipulate user passwords and escalate their privileges in Active Directory . /id (optional) – user RID. Here’s what I’ve done so far: used the web shell to get a more stable reverse shell with nc. defaulted to cme. Mimikatz facilitates password hash extraction from the Local Security Authority Subsystem (LSASS). As a snamestring, U2U is employed to obtain a service ticket for an unprivileged user (Elliot. This command executes the sekurlsa::digestsdump command, which digs up SHA-1 hashes of all currently running processes. Administrator). token::elevate # List users and hashes of the machine lsadump::sam # Enable debug mode for our user privilege::debug # List users logged in the machine and still in memory sekurlsa::logonPasswords full # Pass The Hash attack in windows: # 1. You can think of a pass the ticket This lets a possible attacker impersonate a network user. From Windows 8. This is typically either his userPrincipalName or mail attribute from the on-prem AD. Pass the key — This gets a unique key, which is used for authentication on a domain controller. Using Mimikatz, the attacker was then able to impersonate the “localadmin” account and gain unauthorized access to the hardened PC. Another way to get your hands on an NTLM hash is to steal it from a machine you have compromised. exe to gain a stable shell on the second box used mimikatz to dump #Discover domain joined computers that have Unconstrained Delegation enabled Get-NetComputer -UnConstrained #List tickets and check if a DA or some High Value target has stored its TGT Invoke-Mimikatz -Command '"sekurlsa::tickets"' #Command to monitor any incoming sessions on our compromised server Invoke-UserHunter -ComputerName Pass-the-Ticket (PtT) involves grabbing an existing Kerberos ticket and using it to impersonate a user. Token impersonation is a technique you can use as local admin to impersonate another user logged on to a system. However, I would like to get the cleartext password of a specific user account using the KERBEROS command. I gave the standard user "Joe" SeImpersonatePrivilege on Windows Server 2008 R2, the only domain controller on the network. Password change on behalf of the user does not have any impact on the ticket, the access can be granted without the user's password (or hash) Mimikatz does not support other user than a Domain Admin (it is hardcoded in the source), by the way I managed to impersonate a domain controller //with some malfunctions. Once an attacker gains access to credentials using Mimikatz, they can use this information for various malicious purposes, including: Impersonating Legitimate Users: Attackers can use stolen credentials to impersonate legitimate users, gaining unauthorized access to sensitive data or systems. Use Mimikatz to generate a TGT for the target domain using the trust key: The first impersonation feature I implemented was the ability to impersonate a user with the current PowerShell thread. Mimikatz is a post-exploitation tool, written by Benjamin Delpy (gentilkiwi), which bundles together some of the most useful post exploitation tasks. NTLM password hash of the AZUREADSSOACC account, e. Mimikatz: This tool is invaluable for inspecting Mimikatz Mimikatz Table of contents lsaiso # Lets inject our own malicious Security Support Provider into memory # require mimilib.
