DSInternals VS BloodHound

Thirdly dsinternals suite can be used to resurrect domain controllers from the dead.. it works very well and is pretty easy - https://github.com/MichaelGrafnetter/DSInternals/blob/master/Documentation/PowerShell/New-ADDBRestoreFromMediaScript.md - the person who created this is nothing short of a wizard.

Greetings. I would like to get recommendations for tools that will allow me to audit the password strength of users in Windows Active Directory and Google Workspace. I came across this one for AD that I plan to try. https://github.com/MichaelGrafnetter/DSInternals/blob/master/Documentation/PowerShell/Test-PasswordQuality.md

As you have no AD specific backup or recovery plan nor do you have an idea of when ransomware was copied into the environment I.e. how long was it sitting dormant? I’d suggest you take the backup you have then use this script from DSInternals - https://github.com/MichaelGrafnetter/DSInternals/blob/master/Documentation/PowerShell/New-ADDBRestoreFromMediaScript.md - to restore ONLY Active Directory (NTDS + SYSVOl) into clean media (needs to be the same major OS version).

Note**:** The same can be done using the DSInternals Set-SamAccountPasswordHash command.

To find out, you can use the DSInternals command Test-PasswordQuality. It will extract the password hashes for all your user accounts and compare them against the password hashes for a dictionary of weak passwords.

Recovery is still an option with this module: https://github.com/MichaelGrafnetter/DSInternals/blob/master/Documentation/PowerShell/New-ADDBRestoreFromMediaScript.md

Load DSInternals Powershell Module (Install-Module DSInternals -Force OR https://github.com/MichaelGrafnetter/DSInternals

FYI, there's a PS module you can use to check passwords. Here's a link to some info about that: https://github.com/MichaelGrafnetter/DSInternals/blob/master/Documentation/PowerShell/Get-ADReplAccount.md

Tool Language Url Notes SharpHound .NET 4 executable https://github.com/BloodHoundAD/SharpHound/ Also possible to be executed in-memory using Cobalt Strike, check @william_knows’ blog post AzureHound PowerShell https://github.com/BloodHoundAD/AzureHound/ Specifically for Azure environments, outside of the scope of this article SharpHound.ps1 PowerShell https://github.com/BloodHoundAD/BloodHound/ Available from the Collectors folder. Using PowerShell reflectively loads the embedded SharpHound.exe .NET executable. It exposes the Invoke-BloodHound function which calls the main function of the SharpHound binary.

BOFHound Python https://github.com/fortalice/bofhound/ Generate BloodHound compatible JSON from logs written by ldapsearch BOF and pyldapsearch.

Run Sharphound and bloodhound Bloodhound. It is excellent in determining relationships and privilege escalation paths that would allow the access.

BloodHound is a web application that identifies and visualizes attack paths in Active Directory environments. It identifies the fastest series of steps from any AD account or machine to a desired target, such as membership in the Domain Admins group. Regularly checking your AD using BloodHound can be an effective defense mechanism that helps you ensure that compromising an account or machine doesn’t enable an attacker to compromise your domain.

Bloodhound - AD attack path management/enumeration

I solved it by grabbing a new version of Sharphound.ps1 on the attack box, you can find it here: https://github.com/BloodHoundAD/BloodHound/tree/master/Collectors.

No live event would be complete without sessions. There were over 30 speakers who covered topics from starting a career in InfoSec, to in-depth sessions about using specific tools like BloodHound. Here are just a few high-level themes and highlights. All of these sessions, including mine, will be made available on the BSidesSLC YouTube channel soon.

If you're planning to use Active Directory and/or Azure AD, run ADRecon/AzureADRecon and Bloodhound frequently and review in depth. Run ScoutSuite frequently and review as part of a normal operational cycle (e.g., at weekly team meetings make the results available and set aside 15 minutes to discuss and make assignments). Look critically at where these three tools overlap within two or three degrees of separation from your jump hosts (e.g., hosts/nodes that are one or two devices away and users/security groups that are one or two devices away) for help prioritizing when you have too many high-risk/high-impact items to look through.
