Inveigh: A Windows PowerShell LLMNR/NBNS Spoofer With Challenge/Response Capture Over HTTP/SMB.
Inveigh is a Windows PowerShell LLMNR/NBNS spoofer designed to assist penetration testers that find themselves limited to a Windows system.
This can commonly occur while performing phishing attacks, USB drive attacks, VLAN pivoting, or simply being restricted to a Windows system as part of client imposed restrictions.
Notes
- Currently supports IPv4 LLMNR/NBNS spoofing and HTTP/SMB NTLMv1/NTLMv2 challenge/response capture.
- LLMNR/NBNS spoofing is performed through sniffing and sending with raw sockets.
- SMB challenge/response captures are performed by sniffing over the host system's SMB service.
- HTTP challenge/response captures are performed with a dedicated listener.
- The local LLMNR/NBNS services do not need to be disabled on the host system.
- LLMNR/NBNS spoofer will point victims to host system's SMB service, keep account lockout scenarios in mind.
- Kerberos should downgrade for SMB authentication due to spoofed hostnames not being valid in DNS.
- Ensure that the LMMNR,NBNS,SMB,HTTP ports are open within any local firewall on the host system.
- Output files will be created in current working directory.
- If you copy/paste challenge/response captures from output window for password cracking, remove carriage returns.
