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. Being introduced to, and getting to know your tester is an often overlooked part of the process. Here's how. Head over to the Ingestors folder in the BloodHound GitHub and download SharpHound.exe to a folder of your choice. https://blog.riccardoancarani.it/bloodhound-tips-and-tricks/, BloodHound: Six Degrees of Domain Admin BloodHound 3.0.3 documentation, Extending BloodHound: Track and Visualize Your Compromise, (Javascript webapp, compiled with Electron, uses. if we want to do more enumeration we can use command bloodhound which is shortend command for Invoke-Sharphound script . Or you want to run a query that would take a long time to visualize (for example with a lot of nodes). Lets find out if there are any outdated OSes in use in the environment. You signed in with another tab or window. The app collects data using an ingester called SharpHound which can be used in either command line, or PowerShell script. Use with the LdapUsername parameter to provide alternate credentials to the domain The more data you hoover up, the more noise you will make inside the network. Before we continue analysing the attack, lets take a quick look at SharpHound in order to understand the attackers tactics better. SharpHound is the executable version of BloodHound and provides a snapshot of the current active directory state by visualizing its entities. Hopefully the above has been a handy guide for those who are on the offensive security side of things however BloodHound can also be leveraged by blue teams to track paths of compromise, identify rogue administrator users and unknown privilege escalation bugs. This specific tool, requires a lot of practice, and studying but mastering it, will always give you the ability to gain access to credentials, and breaking in. It can be installed by either building from source or downloading the pre-compiled binaries OR via a package manager if using Kali or other Debian based OS. Earlier versions may also work. Use Git or checkout with SVN using the web URL. Thankfully, we can find this out quite easily with a Neo4j query. collect sessions every 10 minutes for 3 hours. This information are obtained with collectors (also called ingestors). For example, to tell When you decipher 12.18.15.5.14.25. The rightmost button opens a menu that allows us to filter out certain data that we dont find interesting. 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. 47808/udp - Pentesting BACNet. WebSharpShooter is a payload creation framework for the retrieval and execution of arbitrary CSharp source code. See details. See the blogpost from Specter Ops for details. As it runs, SharpHound collects all the information it can about AD and its users, computers and groups. He is a Microsoft Cloud and Datacenter Management MVP who absorbs knowledge from the IT field and explains it in an easy-to-understand fashion. In the Projects tab, rename the default project to "BloodHound.". The wide range of AD configurations also allow IT administrators to configure a number of unsafe options, potentially opening the door for attackers to sneak through. This switch modifies your data collection Based off the info above it works perfect on either version. Log in with the default username neo4j and password neo4j. Maybe it could be the version you are using from bloodhound.ps1 or sharphound.ps1. SharpHound outputs JSON files that are then fed into the Neo4j database and later visualized by the GUI. We want to particularly thank the community for a lot of suggestions and fixes, which helped simplify the development cycle for the BloodHound team for this release. Whatever the reason, you may feel the need at some point to start getting command-line-y. Both ingestors support the same set of options. information from a remote host. periods. When SharpHound is done, it will create a Zip file named something like 20210612134611_BloodHound.zip inside the current directory. SharpHound.ps1 Invoke-BloodHound -CollectionMethod All --LdapUsername --LdapPassword --OutputDirectory Then we can capture its TGT, inject it into memory and DCsync to dump its hashes, giving ous complete access over the whole forest.

The best way of doing this is using the official SharpHound (C#) collector. ) Navigate to the folder where you installed it and run. This is the original query: MATCH (u:User) WHERE u.lastlogon > (datetime().epochseconds - (90 * 86400)) AND NOT u.lastlogon IN [-1.0, 0.0] RETURN u.name. This will take more time, but EDR or monitoring solutions may catch your collection more quickly if you run multi-threaded. Whenever in doubt, it is best to just go for All and then sift through it later on. MK18 2LB You may find paths to Domain Administrator, gain access and control over crucial resources, and discern paths for lateral movement towards parts of the environment that are less heavily monitored than the workstation that served as the likely initial access point. You have the choice between an EXE or a Another interesting query is the one discovering users that have not logged in for 90 (or any arbitrary amount of) days. Neo4j is a graph database management system, which uses NoSQL as a graph database. Now well start BloodHound. Extract the file you just downloaded to a folder. Which naturally presents an attractive target for attackers, who can leverage these service accounts for both lateral movement and gaining access to multiple systems. In actual, I didnt have to use SharpHound.ps1. By default, SharpHound will output zipped JSON files to the directory SharpHound This can generate a lot of data, and it should be read as a source-to-destination map.

No, it was 100% the call to use blood and sharp. You can stop after the Download the BLoodHound GUI step, unless you would like to build the program yourself. To the left of it, we find the Back button, which also is self-explanatory. This has been tested with Python version 3.9 and 3.10. Ensure you select Neo4JCommunity Server. When obtaining a foothold on an AD domain, testers should first run SharpHound with all collection methods, and then start a loop collection to enumerate more sessions. Collect every LDAP property where the value is a string from each enumerated Instruct SharpHound to only collect information from principals that match a given Upload the .zip file that SharpHound generated by pressing Upload and selecting the file. But structured does not always mean clear. The second option will be the domain name with `--d`. The front-end is built on electron and the back-end is a Neo4j database, the data leveraged is pulled from a series of data collectors also referred to as ingestors which come in PowerShell and C# flavours. `--Throttle` and `--Jitter` options will introduce some OpSec-friendly delay between requests (Throttle), and a percentage of Jitter on the Throttle value. This allows you to target your collection. Collecting the Data Back to the attack path, we can set the user as the start point by right clicking and setting as start point, then set domain admins as endpoint, this will make the graph smaller and easier to digest: The user [emailprotected] is going to be our path to domain administrator, by executing DCOM on COMP00262.TESTLAB.LOCAL, from the information; The user [emailprotected] has membership in the Distributed COM Users local group on the computer COMP00262.TESTLAB.LOCAL.
