Attack Active Directory: Enumeration

-

MITM and Samba exploits not working?

1. Kerberos Username Enumeration

Download Here: https://github.com/ropnop/kerbrute/releases. Install, chmod the file, thats it.

2. LDAP Enumeration

Check out: https://book.hacktricks.xyz/network-services-pentesting/pentesting-ldap and https://www.n00py.io/2020/02/exploiting-ldap-server-null-bind/

>>> import ldap3
>>> server = ldap3.Server('x.X.x.X', get_info = ldap3.ALL, port =636, use_ssl = True)
>>> connection = ldap3.Connection(server)
>>> connection.bind()
True
>>> server.info
>>> connection.search(search_base='DC=vault,DC=offsec', search_filter='(&(objectClass=*))', search_scope='SUBTREE', attributes='*')
>>> connection.entries
>>> connection.search(search_base='DC=htb,DC=local', search_filter='(&(objectClass=person))', search_scope='SUBTREE', attributes='userPassword')
>>> connection.entries

Change use_ssl to False if it doesn't connect. Different ports like 3268 can work. Check description field for accidental passwords.

3. Bloodhound

Benefit of BloodHound: Make pretty graphs for clients to understand. Also to visualize what is going on in the domain.

On Kali: 
sudo apt install bloodhound
sudo neo4j console (default creds: neo4j/neo4j)
bloodhound
On Active Directory:

Get Collector Here: https://github.com/BloodHoundAD/BloodHound/tree/master/Collectors

powershell -ep bypass
. .\SharpHound.ps1
Invoke-BloodHound -CollectionMethod All -Domain vulcan.local -ZipFileName file.zip

Next: Go to (bloodhound) instance and upload the file. Run different queries to obtain graphs.

Invoke-BloodHound can take awhile.

4. PowerView

powershell -ep bypass -nop
. .\PowerView.ps1
Get-NetDomain
Get-NetDomainController (info about Domain Controller, if you can't find it)
Get-DomainPolicy
(Get-DomainPolicy).SystemAccess
Get-NetUser
Get-NetUser | select cn
Get-NetUser | select cn, description
Get-UserProperty -Properties pwdlastset
Get-NetGroup -GroupName *admin*
Get-NetGroupMember -GroupName "Domain Admins"
Invoke-ShareFinder
Get-NetGPO (show client what bad group policies they have)

Brad Traversy MySQL CheatSheet PentestMonkey SQL CheatSheet MySQL Statement Architecture Jarvis Walkthrough Step 1 - Try to make your query. Visualize it.

Palo Alto for GNS3 CCDC Tutorial

Opening Hello fellow CCDC Competitors! Struggling to get a Palo-Alto VM? I know how you can get one! Email me at ASzampiasSWD@gmail.com. I'll tell you the steps to get a PA-VM for GNS3. Why am I giving this info to you? Wouldn't it make sense to hog the info to myself? Wouldn't my team have an advantage? There are have and have not universities when it comes to PaloAltos. I fell into the "have not" group. Our college didn't have access to PA-VMs and still doesn't. Even if PA Cybersecurity Academy is free, there is too much red tape. I can't change the outcome. I can only come up with this one solution. Another reason is Tri-C is a tryout team. I think its pretty unfair as a potential Firewall Admin I'm the only one with access. No one can challenge me unless they spend 2K for a PA-VM. It becomes a rich-person only position. I have a leftover PA-VM from 2018 I promised not to share. I couldn't share that with my challengers. But I f

Trace Labs CTF V TraceLabs hosted the Global Missing Persons CTF V event on July 11, 2020. My team //synergy got 64th place out of 190 teams. Introduction This was my first Trace Labs CTF. I captained a team. The good thing about being a captain is you can control who is on the team. My rules were: Must have sock puppet accounts ready. Must have a VPN. Writing out this is a competitive team where we work the entire 6 hours. I was worried about a future team member spamming submissions and disqualifying the team. I thought my requirements would eliminate people who weren't serious. The team hit 4 members Friday evening pretty quickly. Notes My laptop was too slow for this event. My virtual machine froze and I had to restart. Restarting means I have to login to my accounts again. I'll use my desktop next time. The team used Slack and Trello. Our strategy was to research a person and rotate every hour. This strategy broke after 1 rotation. Some missin
