# Description:
# This script implements a child-domain to forest privilege escalation
# as detailed by Sean Metcalf (@PyroTek3) at https://adsecurity.org/?p=1640. We will
# be (ab)using the concept of Golden Tickets and ExtraSids researched and implemented
# by Benjamin Delpy (@gentilkiwi) in mimikatz (https://github.com/gentilkiwi/mimikatz).
# The idea of automating all these tasks came from @mubix.
#
# The workflow is as follows:
# Input:
# 1) child-domain Admin credentials (password, hashes or aesKey) in the form of 'domain/username[:password]'
# The domain specified MUST be the domain FQDN.
# 2) Optionally a pathname to save the generated golden ticket (-w switch)
# 3) Optionally a target-user RID to get credentials (-targetRID switch)
# Administrator by default.
# 4) Optionally a target to PSEXEC with the target-user privileges to (-target-exec switch).
# Enterprise Admin by default.
#
# Process:
# 1) Find out where the child domain controller is located and get its info (via [MS-NRPC])
# 2) Find out what the forest FQDN is (via [MS-NRPC])
# 3) Get the forest's Enterprise Admin SID (via [MS-LSAT])
# 4) Get the child domain's krbtgt credentials (via [MS-DRSR])
# 5) Create a Golden Ticket specifying SID from 3) inside the KERB_VALIDATION_INFO's ExtraSids array
# and setting expiration 10 years from now
# 6) Use the generated ticket to log into the forest and get the target user info (krbtgt/admin by default)
# 7) If file was specified, save the golden ticket in ccache format
# 8) If target was specified, a PSEXEC shell is launched
#
# Output:
# 1) Target user credentials (Forest's krbtgt/admin credentials by default)
# 2) A golden ticket saved in ccache for future fun and profit
# 3) PSExec Shell with the target-user privileges (Enterprise Admin privileges by default) at target-exec
# parameter.
#
# IMPORTANT NOTE: Your machine MUST be able to resolve all the domains from the child domain up to the
# forest. Easiest way to do is by adding the forest's DNS to your resolv.conf or similar
#
# E.G:
# Just in case, Microsoft says it all (https://technet.microsoft.com/en-us/library/cc759073(v=ws.10).aspx):
# A forest is the only component of the Active Directory logical structure that is a security boundary.
# By contrast, a domain is not a security boundary because it is not possible for administrators from one domain
# to prevent a malicious administrator from another domain within the forest from accessing data in their domain.
# A domain is, however, the administrative boundary for managing objects, such as users, groups, and computers.
# In addition, each domain has its own individual security policies and trust relationships with other domains.
