You have the choice between an EXE or a PS1 file. This allows you to tweak the collection to only focus on what you think you will need for your assessment. Run pre-built analytics queries to find common attack paths, Run custom queries to help in finding more complex attack paths or interesting objects, Mark nodes as high value targets for easier path finding, Mark nodes as owned for easier path finding, Find information about selected nodes: sessions, properties, group membership/members, local admin rights, Kerberos delegations, RDP rights, outbound/inbound control rights (ACEs), and so on, Find help about edges/attacks (abuse, OPSEC considerations, references), Using BloodHound can help find attack paths and abuses like. Lets find out if there are any outdated OSes in use in the environment. Now, download and run Neo4j Desktop for Windows. We can simply copy that query to the Neo4j web interface. A pentester discovering a Windows Domain during post-exploitation, which will be the case in many Red Team exercises, will need to assess the AD environment for any weaknesses. It is well possible that systems are still in the AD catalog, but have been retired long time ago. Note: This product has been retired and is replaced by Sophos Scan and Clean. Active Directory object. SharpHound outputs JSON files that are then fed into the Neo4j database and later visualized by the GUI. A tag already exists with the provided branch name. MATCH (u:User)-[:MemberOf]->(g:Group) WHERE g.name CONTAINS "OPERATIONS00354" AND u.lastlogon > (datetime().epochseconds - (90 * 86400)) AND NOT u.lastlogon IN [-1.0, 0.0] RETURN u.name.

The second one, for instance, will Find the Shortest Path to Domain Admins. This feature set is where visualization and the power of BloodHound come into their own, from any given relationship (the lines between nodes), you can right click and view help about any given path: Within the help options of the attack path there is info about what the relationship is, how it can be abused and what operational security (opsec) considerations need to be taken into account: In the abuse info, BloodHound will give the user the exact commands to drop into PowerShell in order to pivot through a node or exploit a relationship which is incredibly useful in such a complicated path. On the bottom left, we see that EKREINHAGEN00063 (and 2 other users) is member of a group (IT00082) that can write to GPO_16, applicable to the VA_USERS Group containing SENMAN00282, who in turn is a DA.

After collecting AD data using one of the available ingestors, BloodHound will map out AD objects (users, groups, computers, ) and accesses and query these relationships in order to discern those that may lead to privilege escalation, lateral movement, etc. To set this up simply clone the repository and follow the steps in the readme, make sure that all files in the repo are in the same directory. Or you want to run a query that would take a long time to visualize (for example with a lot of nodes). The following lines will enable you to query the Domain from outside the domain: This will prompt for the users password then should launch a new powershell window, from here you can import sharphound as you would normally: This window will use the local DNS settings to find the nearest domain controller and perform the various LDAP lookups that BloodHound normally performs. The app collects data using an ingester called SharpHound which can be used in either command line, or PowerShell script. Conduct regular assessments to ensure processes and procedures are up to date and can be followed by security staff and end users. A list of all Active Directory objects with the any of the HomeDirectory, ScriptPath, or ProfilePath attributes set will also be requested. This data can then be loaded into BloodHound (mind you, you need to unzip the MotherZip and drag-and-drop-load the ChildZips, which you can do in bulk). We first describe we want the users that are member of a specific group, and then filter on the lastlogon as done in the original query. Value is in milliseconds (Default: 0), Adds a percentage jitter to throttle. Whenever the pre-built interface starts to feel like a harness, you can switch to direct queries in the Neo4j DB to find the data and relations you are looking for. See the blogpost from Specter Ops for details. BloodHound can do this by showing previously unknown or hidden admin users who have access to sensitive assets such as domain controllers, mail servers or databases.
