BloodHound is 10 🎉 To celebrate, creators @_wald0, @CptJesus & @harmj0y joined for a special two-part #KnowYourAdversary. They reminisce on the first attack graphs and look ahead to what’s next for BloodHound. 1️⃣: ghst.ly/4xT4WdA 2️⃣: ghst.ly/4zIIeqj
I can't believe it's already been 10 years, what an insane ride! At this point I'm sure we'll all have BloodHound etched on our tombstones (maybe @_wald0 will have 'Thought in graphs...' 😂) - it truly was an honor working on this project with these two <3

See you all next week...excited to present with @breakfix at #BHEU! 💣
SCOM monitors critical systems, but insecure defaults make it a powerful attack vector. At #BHEU, @unsigned_sh0rt & @breakfix show how to abuse SCOM for credential theft, lateral movement, and domain escalation, plus how to defend it. ghst.ly/4aoggph

Check out my new blog on nested app authentication and brokered authentication.
Why should Microsoft's Nested App Authentication (NAA) should be on your security team's radar? @Icemoonhsv breaks down NAA and shows how attackers can pivot between Azure resources using brokered authentication. ghst.ly/45h2Zw3
Dear fellow pentesters & red teamers, How often do you run into a vCenter in your client’s environment? 🖥️ I just built one for vCenter - meet vCenterHound 🐾😉 This is just the beginning… more collectors and surprises are on the way. #Pentesting #RedTeam #BloodHound #vCenter
This post about MSSQLHound, a PowerShell collector that adds 7 new nodes and 37 new edges to BloodHound, details my experience and lessons learned designing and implementing the tool using OpenGraph and provides examples of how to research and discover MSSQL attack paths.
MSSQLHound leverages BloodHound's OpenGraph to visualize MSSQL attack paths with 7 new nodes & 37 new edges, all without touching the SharpHound & BloodHound codebases. @_Mayyhem unpacks this new feature in his blog post. 👇 ghst.ly/4leRFFn
MSSQL support just landed in BloodHound! You can now map out how attackers might use SQL servers to move laterally. This is incredibly useful in hybrid and legacy heavy environments. Let us know what you find. Learn more ➡️ ghst.ly/MSSQLHound
