I'm SO hyped to finally make MSSQLHound public! It's a new BloodHound collector that adds 37 new edges and 7 new nodes for MSSQL attack paths using the new OpenGraph feature for 8.0!. Let me know what you find with it! - github.com/SpecterOps/MSS… - specterops.io/blog/2025/07/2…
Entra Connect sync accounts can be exploited to hijack device userCertificate properties, enabling device impersonation and conditional access bypass. @hotnops explores cross-domain compromise tradecraft within the same tenant. Read more ⤵️ ghst.ly/3ISMGN9
BloodHound v8.0 is here! 🎉 This update introduces BloodHound OpenGraph, revolutionizing Identity Attack Path Management by exposing attack paths throughout your entire tech stack, not just AD/Entra ID. Read more from @JustinKohler10: ghst.ly/bloodhoundv8 🧵: 1/7
I publish two blog posts today! 📝🐫 The first dives into how we're improving the way BloodHound models attack paths through AD trusts: specterops.io/blog/2025/06/2… The second covers an attack technique I came across while exploring AD trust abuse: specterops.io/blog/2025/06/2…
BadSuccessor is a new AD attack primitive that abuses dMSAs, allowing an attacker who can modify or create a dMSA to escalate privileges and take over the forest. Check out @JimSycurity's latest blog post to understand how you can mitigate risk. ghst.ly/4kXTLd9
Took @akamai_research's script for BadSuccessor and improved it a bit. - runs from non domain joined systems - works in forests - prints the rights each entity has on a OU - pre-flight check if 2025 DCs are present - code changes here and there github.com/LuemmelSec/Pen…
Any data hoarders out there happen to have an ISO of Exchange 2010 RC from 2009? techcommunity.microsoft.com/blog/exchange/… And this is why I want it: techcommunity.microsoft.com/blog/exchange/…
Think NTLM relay is a solved problem? Think again. Relay attacks are more complicated than many people realize. Check out this deep dive from @elad_shamir on NTLM relay attacks & the new edges we recently added to BloodHound. ghst.ly/4lv3E31
Active Directory isn't going anywhere, but security pros lack key knowledge. 🧠 Join Jim Sykora & @DFIRdeferred at @BSidesCharm for their AD Security 101 training, which aims to give you tools to find & fix misconfigurations attackers exploit. bsidescharm.org
I'm excited that my first PRs to BloodHound/SharpHound are now in main! They remove FPs for Owns/WriteOwner edges when implicit owner rights are blocked and add OwnsLimitedRights and WriteOwnerLimitedRights edges when ACEs grant permissions to the OWNER RIGHTS SID. More to come!
