What is NTLMrelayx6?

ntlmrelayx 6 is a tool used in penetration testing and security assessments to perform NTLM relay attacks. NTLM (NT LAN Manager) is a suite of Microsoft security protocols that provides authentication, integrity, and confidentiality to users. NTLM relay attacks exploit weaknesses in NTLM authentication to intercept and relay authentication requests to gain unauthorized access to network resources.

ntlmrelayx 6 is an updated version of the original ntlmrelayx tool, enhanced to support modern attack scenarios and environments. It automates the process of intercepting NTLM authentication requests, relaying them to target systems, and executing specific actions, such as capturing credentials, escalating privileges, or executing arbitrary commands.

Commands

ntlmrelayx 6 offers a range of commands and options for conducting NTLM relay attacks. Some common commands include:

ntlmrelayx.py -t TARGET -smb2support

• -t TARGET: Specifies the target system or network to relay authentication requests to.
• -smb2support: Enables SMBv2 support for relaying authentication requests over SMBv2.
