NTLM Relay
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…

Just a walkthrough of how to escalate privileges locally by forcing the system you landed initial access on to reflectively authenticate over HTTP to itself and forward the received connection to an HTTP listener (ntlmrelayx) configured to relay to DC servers over LDAP/LDAPs for either setting shadow credentials or configuring RBCD.

🔑 Pass-the-Challenge
This blog post introduces new techniques for recovering the NTLM hash from an encrypted credential protected by Windows Defender Credential Guard. While previous techniques for bypassing Credential Guard focus on attackers targeting new victims who log into a compromised server, these new techniques can also be applied to victims logged on before the server was compromised.

A new vulnerability related to capturing NTLMv2 hashes via Office URI schemes has been discovered. The http:// protocol can be used for attacks such as NTLM relay to a Domain Controller.
Microsoft 365 and Office 2019 versions are vulnerable, as they open remote files without warnings, unlike earlier versions. The exploit involves using a 302 redirect and abusing GPO misconfigurations to capture NTLMv2 hashes over SMB and HTTP.
