Lsass Dumping
Now we are aware of dumping credentials in memory and running tools on the OS host, but we have offline methods as well, where the operator can dump the lsass process and attack the file offline. One tool that allows us this is the Task Manager itself, it will create a Dumps' file of the process for inspection, but we can grab this file and attack it offline
Requires Administrator Permissions
TaskManager
The file is dumped successfully in the mentioned folder location
We can grab this file and move it offline for dumping credentials
Requires SYSTEM permissions
MinidumpW
A LOLBAS is available for dumping the lsass process, the required permission is SYSTEM we can use the following command to dump the process onto a file

We can do the same with mimikatz and attack the file offline
