synacktiv/prox-ezProxy de intercepção HTTP/HTTPS para testar mecanismos de autenticação do Windows, com suporte a NTLM, Kerberos, pass-the-hash, pass-the-ticket e ataques de relay, incluindo geração de certificados integrada para MITM.
Este proxy HTTP trata de todas as autenticações HTTP em seu nome.
Ele suporta NTLM EPA (channel binding e service binding), kerberos, pass-the-hash, overpass-the-hash (pass-the-key) e pass-the-ticket (TGT e TGS).

Execute assim: ele tentará autenticar com as credenciais mydomain/myusername:mypassword em qualquer site que exija autenticação:
python3 proxy.py -dc mydomain/myusername:mypassword
O mesmo, mas usando hash NT em vez de senha:
python3 proxy.py -dc mydomain/myusername --hashes :31d6cfe0d16ae931b73c59d7e0c089c0
Para funcionar com o BurpSuite:
Project options -> HTTP -> HTTP/2 -> desmarque Enable HTTP/2Set response header "Connection: close", pois o NTLM autentica uma conexão TCP: Proxy -> Options -> Miscellaneous -> desmarque Set response header "Connection: close".Set "Connection" header on incoming requests when using HTTP/1: Proxy -> Options -> Miscellaneous -> desmarque Set "Connection" header on incoming requests when using HTTP/1Depois, basta especificar um proxy upstream no Burp, para que ele use este proxy para o host com o qual você não consegue autenticar:
Project options -> Connections -> Upstream Proxy Servers -> clique em Add -> especifique o hostname remoto que está causando problemas com a autenticação NTLM, o host e a porta do proxy configurados na ferramenta e deixe o Authentication type como None.$ python3 proxy.py -h

optional arguments:
-h, --help show this help message and exit
--listen-address LISTEN_ADDRESS, -l LISTEN_ADDRESS
Address the proxy will be listening on, defaults to 127.0.0.1.
--listen-port LISTEN_PORT, -p LISTEN_PORT
Port the proxy will be listening on, defaults to 3128.
--cacert CACERT Filepath to the CA certificate, defaults to ./cacert.pem. Will be created if it does not exists.
--cakey CAKEY Filepath to the CA private key, defaults to ./cakey.pem. Will be created if it does not exists.
--cakey-pass CAKEY_PASS
CA private key passphrase.
--certsdir CERTSDIR Path to the directory the generated certificates will be stored in, defaults to /tmp/Prox-Ez. Will be created if it does not exists.
--singleprocess, -sp Do you want to be slowwwww ?! Actually useful during debug.
--debug, -d Increase debug output.
--dump-keys DUMP_KEYS, -dk DUMP_KEYS
File to dump the SSL/TLS keys to. Useful when trying to debug. When this option is specified, --singleprocess is implied.
--creds CREDS Path to the credentials file, for instance: { "my.hostname.com": { "creds": "domain/user:password", "spn": "HTTP/anothername" }, "my.second.hostname.com": { "creds": "domain1/user1", "hashes": ":nthash1" } }
--default-creds DEFAULT_CREDS, -dc DEFAULT_CREDS
Default credentials that will be used to authenticate.
--hashes HASHES Could be used instead of password. It is associated with the domain and username given via --default_creds. format: lmhash:nthash or :nthash.
--kerberos, -k Enable kerberos authentication instead of NTLM.
--dcip DCIP IP Address of the domain controller (only for kerberos).
--spn SPN Use the provided SPN when an SPN is needed. More details in the article.
--spn-force-fqdn Force the usage of the FQDN as the SPN instead of what was specified in the URL.
--no-epa Deactivate the NTLM EPA feature.
