Finding the Shortest Path from a User C# Data Collector for the BloodHound Project, Version 3. As usual, you can grab compiled versions of the user interface and the collector from here, or self-compile from our GitHub repository for BloodHound and SharpHound. Theyre global. BloodHound will import the JSON files contained in the .zip into Neo4j. But structured does not always mean clear. Specifically, it is a tool Ive found myself using more and more recently on internal engagements and when compromising a domain as it is a quick way to visualise attack paths and understand users active directory properties. from. Mind you this is based on their name, not what KBs are installed, that kind of information is not stored in AD objects. By leveraging this you are not only less likely to trigger antivirus, you dont have to exfiltrate the results either which reduces the noise level on the network. information from a remote host. Ingestors are the main data collectors for BloodHound, to function properly BloodHound requires three key pieces of information from an Active Directory environment, these are. When you decipher 12.18.15.5.14.25. That is because we set the Query Debug Mode (see earlier). This can help sort and report attack paths. To follow along in this article, you'll need to have a domain-joined PC with Windows 10. Open a browser and surf to https://localhost:7474. 12 Installation done. Now well start BloodHound. SharpHound outputs JSON files that are then fed into the Neo4j database and later visualized by the GUI. The different notes in BloodHound are represented using different icons and colours; Users (typically green with a person), Computers (red with a screen), Groups (yellow with a few people) and Domains (green-blue with a globe like icon). Rubeus offers outstanding techniques to gain credentials, such as working with the Kerberos and abuses of Microsoft Windows. as. DCOnly collection method, but you will also likely avoid detection by Microsoft By not touching Import may take a while. If you'd like to run Neo4j on AWS, that is well supported - there are several different options. attempt to collect local group memberships across all systems in a loop: By default, SharpHound will loop for 2 hours. Again, an OpSec consideration to make. Instruct SharpHound to only collect information from principals that match a given In the last example, a GenericWrite on a high-privileged group allows you to add users to it, but this may well trigger some alerts. To identify usage of BloodHound in your environment it is recommended that endpoints be monitored for access and requests to TCP port 389(LDAP) and TCP port 636(LDAPS) and similar traffic between your endpoints and your domain controllers. When SharpHound is scanning a remote system to collect user sessions and local Interestingly, on the right hand side, we see there are some Domain Admins that are Kerberoastable themselves, leading to direct DA status. 5 Pick Ubuntu Minimal Installation. In some networks, DNS is not controlled by Active Directory, or is otherwise The Neo4j database is empty in the beginning, so it returns, "No data returned from query." Note that this is on a test domain and that the data collection in real-life scenarios will be a lot slower. Run SharpHound.exe. common options youll likely use: Here are the less common CollectionMethods and what they do: Image credit: https://twitter.com/SadProcessor.

If you dont have access to a domain connected machine but you have creds, BloodHound can be run from your host system using runas. Just as visualising attack paths is incredibly useful for a red team to work out paths to high value targets, however it is just as useful for blue teams to visualise their active directory environment and view the same paths and how to prevent such attacks. We can simply copy that query to the Neo4j web interface. Collect every LDAP property where the value is a string from each enumerated These accounts are often service, deployment or maintenance accounts that perform automated tasks in an environment or network. However, collected data will contain these values, as shown in the screenshot below, based on data collected in a real environment. Neo4j then performs a quick automatic setup.
