ncrack - Network authentication cracking tool

NAME

       ncrack - Network authentication cracking tool

SYNOPSIS

       ncrack [Options] {target specification}

DESCRIPTION

       Ncrack is an open source tool for network authentication

       cracking. It was designed for high-speed parallel cracking

       using a dynamic engine that can adapt to different network

       situations. Ncrack can also be extensively fine-tuned for

       special cases, though the default parameters are generic

       enough to cover almost every situation. It is built on a

       modular architecture that allows for easy extension to

       support additional protocols. Ncrack is designed for

       companies and security professionals to audit large networks

       for default or weak passwords in a rapid and reliable way.

       It can also be used to conduct fairly sophisticated and

       intensive brute force attacks against individual services.

Warning

           Ncrack is a project started in the Summer of 2009. While

           it is already useful for some purposes, it is still

           unfinished, beta quality software. You can help out by

           testing it and reporting any problems as described in

           the section called “BUGS”.

       The output from Ncrack is a list of found credentials, if

       any, for each of the targets specified. Ncrack can also

       print an interactive status report of progress so far and

       possibly additional debugging information that can help

       track problems, if the user selected that option.

       A typical Ncrack scan is shown in Example 1. The only Ncrack

       arguments used in this example are the two target IP

       addresses along with the the corresponding ports for each of

       them. The two example ports 21 and 22 are automatically

       resolved to the default services listening on them: ftp and

       ssh.

Example 1. A representative Ncrack scan

           $ ncrack 10.0.0.130:21 192.168.1.2:22

           Starting Ncrack 0.6 ( http://ncrack.org ) at 2016-01-03 22:10 EEST

           Discovered credentials for ftp on 10.0.0.130 21/tcp:

           10.0.0.130 21/tcp ftp: admin hello1

           Discovered credentials for ssh on 192.168.1.2 22/tcp:

           192.168.1.2 22/tcp ssh: guest 12345

           192.168.1.2 22/tcp ssh: admin money$

           Ncrack done: 2 services scanned in 156.03 seconds.
