## What is BloodHound
|
||||
## AD Explorer
|
||||
|
||||
[AD Explorer](https://docs.microsoft.com/en-us/sysinternals/downloads/adexplorer) is from Sysinternal Suite:
|
||||
|
||||
> An advanced Active Directory (AD) viewer and editor. You can use AD Explorer to navigate an AD database easily, define favorite locations, view object properties, and attributes without opening dialog boxes, edit permissions, view an object's schema, and execute sophisticated searches that you can save and re-execute.
|
||||
|
||||
### Snapshots
|
||||
|
||||
AD Explorer can create snapshots of an AD so you can check it offline.\
|
||||
It can be used to discover vulns offline, or to compare different states of the AD DB across the time.
|
||||
|
||||
You will be requires the username, password, and direction to connect (any AD user is required).
|
||||
|
||||
To take a snapshot of AD, go to `File` --> `Create Snapshot` and enter a name for the snapshot.
|
||||
|
||||
## ADRecon
|
||||
|
||||
****[**ADRecon**](https://github.com/adrecon/ADRecon) is a tool which extracts and combines various artefacts out of an AD environment. The information can be presented in a **specially formatted** Microsoft Excel **report** that includes summary views with metrics to facilitate analysis and provide a holistic picture of the current state of the target AD environment.
|
||||
|
||||
```bash
|
||||
# Run it
|
||||
.\ADRecon.ps1
|
||||
```
|
||||
|
||||
## BloodHound
|
||||
|
||||
> BloodHound is a single page Javascript web application, built on top of [Linkurious](http://linkurio.us), compiled with [Electron](http://electron.atom.io), with a [Neo4j](https://neo4j.com)database fed by a PowerShell ingestor.

## Trust Account Attack
|
||||
|
||||
When an Active Directory domain or forest trust is set up from a domain _B_ to a domain _A_ (_**B**_ trusts A), a trust account is created in domain **A**, named **B. Kerberos trust keys**,\_derived from the **trust account’s password**, are used for **encrypting inter-realm TGTs**, when users of domain A request service tickets for services in domain B.
|
||||
When an Active Directory domain or forest trust is set up from a domain _B_ to a domain _A_ (_**B**_\*\* trusts **\_**A**\_), a \_**trust account**\_** is created in domain **\_**A**\_**, named **\_**B$**\_. Kerberos \_**trust keys\*\*,\_ derived from the **trust account’s password**, are used for **encrypting inter-realm TGTs**, when users of domain A request service tickets for services in domain B.

|

If you **couldn't** find any **special** access of your user in the other domain, you can still go back to the AD Methodology and try to **privesc from an unprivileged user** (things like kerberoasting for example):
|
||||
|
||||
You can use **Powerview functions** to **enumerate** the **other domain** using the `-Domain` param like in:
|
||||
|
||||
```powershell
|
||||
Get-DomainUser -SPN -Domain domain_name.local | select SamAccountName

## Impersonation
|
||||
|
||||
### Logging in
|
||||
|
||||
Using a regular method with the credentials of the users who is has access to the external domain you should be able to access:
|
||||
|
||||
```powershell
|
||||
Enter-PSSession -ComputerName dc.external_domain.local -Credential domain\administrator
|
||||
```
|
||||
|
||||
### SID History Abuse
|
||||
|
||||
You could also abuse [**SID History**](sid-history-injection.md) across a forest trust.
|
||||
|
||||
If a user is migrated **from one forest to another** and **SID Filtering is not enabled**, it becomes possible to **add a SID from the other forest**, and this **SID** will be **added** to the **user's token** when authenticating **across the trust**.
|
||||
### With signing key
|
||||
|
||||
{% hint style="warning" %}
|
||||
As a reminder, you can get the signing key with
|
||||
|
||||
```powershell

Invoke-Mimikatz -Command '"lsadump::trust /patch"' -ComputerName dc.domain.local
