In the recently released Windows Server 2025 and Windows 11 24H2, several network protocols have been reconfigured to be more secure by default. One of the affected protocols is the Server Message Block (SMB), where message signing is now required under most circumstances. These changes eliminate some NTLM Relay Attack vectors, but do not mitigate this hacking technique completely. The following table summarizes the old and new SMB signing enforcement defaults: Operating System SMB Client SMB...| DSInternals

We’ve just released another open-source tool: pretender, a cross-platform tool to obtain a machine-in-the-middle position inside Windows networks in the spirit of Responder and mitm6. It implements local name resolution spoofing using the mDNS, …| RedTeam Pentesting - Blog
NTLM relay is a technique of standing between a client and a server to perform actions on the server while impersonating the client. Protections such as SMB signing or MIC allow to limit the actions of an attacker. This article goes into detail about this technique to understand how it works and what are its limits.| hackndo
One thing I love is when I think I understand a topic well, and then someone proves me quite wrong. That was more or less what happened when James Forshaw published a blog on Kerberos relaying, which disproves my conclusion that you can’t relay Kerberos from a few years ago. James showed that there are some tricks to make Windows authenticate to a different Service Principal Name (SPN) than what would normally be derived from the hostname the client is connecting to, which means Kerberos is...| dirkjanm.io
