Capture

Theory

After successfully with LM or NTLM to an attacker's server, the attacker can try to recover credentials by capturing and (LM or NTLM hash, a.k.a. response) sent by the victim.

Practice

NTLM capture can be combined with any forced authentication attack. Testers should dissociate the name poisoning features that Responder and Inveigh offer from their capturing features. Those tools can be combined with others offering different "authentication forcing" attacks (like , and so on).

(Python) and (Powershell) are great tools able to do name poisoning for forced authentication attacks, but also able to capture responses (LM or NTLM hashes) by starting servers waiting for incoming authentications. Once those listening servers are up and ready, the tester can initiate the .

In order to help the later , testers need to set the NTLM challenge sent to victims to 1122334455667788.

For Inveigh, it can be defined with a command-line argument. For Responder, testers need to edit the configuration file.

sed -i 's/ Random/ 1122334455667788/g' /PATH/TO/Responder/Responder.conf

From UNIX-like systems, (Python) can be used to start servers listening for NTLM authentications over many protocols (SMB, HTTP, LDAP, FTP, POP3, IMAP, SMTP, ...). Depending on the authenticating principal's configuration, the NTLM authentication can sometimes be downgraded with --lm and --disable-ess in order to obtain NTLMv1 responses.

responder --interface "eth0" --analyze
responder -I "eth0" -A

# with downgrading
responder --interface "eth0" --analyze --lm --disable-ess

Testers should try to force a LM hashing downgrade with Responder. LM and NTLMv1 responses (a.k.a. LM/NTLMv1 hashes) from Responder can easily be cracked with . The tool (Python) can be used to convert captured responses to crackable formats by hashcat, and so on.

ntlmv1-multi --ntlmv1 SV01$::BREAKING.BAD:AD1235DEAC142CD5FC2D123ADCF51A111ADF45C2345ADCF5:AD1235DEAC142CD5FC2D123ADCF51A111ADF45C2345ADCF5:1122334455667788

Machine account NT hashes can be used with the or techniques to gain admin access to it.

There are cases where a downgrade attempt will fail and the capture authentication will not be shown. Testers should always try to capture authentication with and without downgrading.

Start poisoning LLMNR, NBT-NS and mDNS with a custom challenge, enable HTTPS capturing, enable proxy server authentication captures
