|

## Recent Updates
|
||||
|
||||
- Added Active Directory awareness checks to highlight Kerberos-only environments (NTLM restrictions) and time skew issues before attempting ticket-based attacks.
|
||||
- winPEAS.ps1 now reviews AD-integrated DNS ACLs to flag zones where low-privileged users can register/modify records (dynamic DNS hijack risk).
|
||||
- Enumerates high-value SPN accounts and weak gMSA password readers so you can immediately target Kerberoastable admins or abused service accounts.
|
||||
- Surfaces Schannel certificate mapping settings to warn about ESC10-style certificate abuse opportunities when UPN mapping is enabled.
|
||||
|
||||
## Advisory
|
||||
|
||||
All the scripts/binaries of the PEAS Suite should be used for authorized penetration testing and/or educational purposes only. Any misuse of this software will not be the responsibility of the author or of any other collaborator. Use it at your own networks and/or with the network owner's permission.
