Kali is a powerful weapon for infiltrators. Today, we will show beginners how to achieve burst quickly. The tools they need can be found in Kali. Without further ado, let’s get started
1. Open the terminal and run the command Crunch, which is a dictionary generation tool that can generate dictionaries according to users’ requirements. You can refer to the manual for the specific parameters, which can be briefly explained here:
crunch 1 4 charset.lst lalpha -o mypwd.txt
The above command generates a dictionary with a minimum of one character and a maximum of four characters. This dictionary is output to mypwd.txt file (so the -o option is used). Charset.lst lalpha is defined as the lalpha option in charset.lst file.
2 dictionary generation, the following please out of the Hydra, this tool parameters are also a lot of, you can look at the manual, here simply said:
Hydra -l root -w 10 – P PWD. TXT 14 – v – t SSH

– l specify a user name, if you are not sure what is the target user name, that can put all of the user name in the dictionary file, and then use the -l user. TXT to specify a user name, – 10 is to specify no more than 10 s w, – P is specified password dictionary, also is the dictionary file generated in step, can pay attention to the path to find oh, – t is the number of threads, the default is 16, -V is the display of cracking process information, and finally the target IP and protocol.
After running, the target host was successfully cracked, as follows:
