Regarding Active Directory permissions, most people assume that a Deny ACE always wins. It doesn't! Windows stops the access check the moment enough rights are granted — any ACE after that point is never evaluated. New post: managedpriv.com/blog/acl-canon…
The .NET ActiveDirectorySecurity API was built for helpdesk scripts, not ACL fidelity. If you're using it for backup, migration, or exact cloning — you're going to have a bad time. New post: the 9 design problems you need to know. bit.ly/3Rl635L

Remember the CredMarshalInfo trick? If you hadn’t applied the June 2025 patch, CVE-2025-33073 would have been critical. We know that in NTLM local auth, msg 3 is empty:You can drop sign/seal -> from Domain User to DomainAdmin escalation. 😅
@ifexploit @oryair1999 @ShahakMo @safebreach I figured that out. Thanks 🙏

M'm glad to release the tool I have been working hard on the last month: #KrbRelayEx A Kerberos relay & forwarder for MiTM attacks! >Relays Kerberos AP-REQ tickets >Manages multiple SMB consoles >Works on Win& Linux with .NET 8.0 >... GitHub: github.com/decoder-it/Krb…

@decoder_it You’re worth more… You’re awesome and I’m grateful to be working side by side with you 🙌

Is Kerberos relaying so limited? I'd say no, thanks to @tiraniddo CredMarshalTargetInfo trick. In this case, I'm relaying SMB to HTTP (ADCS) with a modified version of @cube0x0 krbrelay using DFSCoerce and PetitPotam - classic ESC8 attack with Kerberos, no DCOM involved ;)

🤫 The part I’m most excited about with my #BHUSA talk is secretly teaching everyone about identity components of #Entra multi-tenant applications and service principals. 🤓 If that sounds boring, pretend you didn’t read this. #BlackHat2024 #infosec #EntraID #foreshadowing
