So far the most significant changes have been:
|
||||
|
||||
- Addition of the Sniffer plugin which integrates Net-Creds (https://github.com/DanMcInerney/net-creds) currently supported protocols are:
|
||||
FTP, IRC, POP, IMAP, Telnet, SMTP, SNMP (community strings), NTLMv1/v2 (all supported protocols like HTTP, SMB, LDAP etc..) and Kerberos
|
||||
|
||||
- Integrated Responder (https://github.com/SpiderLabs/Responder) to poison LLMNR, NBT-NS and MDNS, and act as a WPAD rogue server.
|
||||
|
||||
- Integrated SSLstrip+ (https://github.com/LeonardoNve/sslstrip2) by Leonardo Nve to partially bypass HSTS as demonstrated at BlackHat Asia 2014
