hydra Usage Example

Attempt to login as the root user (-l root) using a password list (-P /usr/share/wordlists/metasploit/unix_passwords.txt) with 6 threads (-t 6) on the given SSH server (ssh://192.168.1.123):

root@kali:~# hydra -l root -P /usr/share/wordlists/metasploit/unix_passwords.txt -t 6 ssh://192.168.1.123
Hydra v7.6 (c)2013 by van Hauser/THC & David Maciejak - for legal purposes only

[DATA] 6 tasks, 1 server, 1003 login tries (l:1/p:1003), ~167 tries per task
[DATA] attacking service ssh on port 22

pw-inspector Usage Example

Read in a list of passwords (-i /usr/share/wordlists/nmap.lst) and save to a file (-o /root/passes.txt), selecting passwords of a minimum length of 6 (-m 6) and a maximum length of 10 (-M 10):

root@kali:~# pw-inspector -i /usr/share/wordlists/nmap.lst -o /root/passes.txt -m 6 -M 10
root@kali:~# wc -l /usr/share/wordlists/nmap.lst

dpl4hydra

Generates a (d)efault (p)assword (l)ist as input for THC hydra

root@kali:~# dpl4hydra -h
dpl4hydra v0.9.9 (c) 2012 by Roland Kessler (@rokessler)

Syntax: dpl4hydra [help] | [refresh] | [BRAND] | [all]

This script depends on a local (d)efault (p)assword (l)ist called
/root/.dpl4hydra/dpl4hydra_full.csv. If it is not available, regenerate it with
'dpl4hydra refresh'. Source of the default password list is
http://open-sez.me

Options:
  help        Help: Show this message
  refresh     Refresh list: Download the full (d)efault (p)assword (l)ist
              and generate a new local /root/.dpl4hydra/dpl4hydra_full.csv file. Takes time!
  BRAND       Generates a (d)efault (p)assword (l)ist from the local file
              /root/.dpl4hydra/dpl4hydra_full.csv, limiting the output to BRAND systems, using
              the format username:password (as required by THC hydra).
              The output file is called dpl4hydra_BRAND.lst.
  all         Dump list of all systems credentials into dpl4hydra_all.lst.

Example:
# dpl4hydra linksys
File dpl4hydra_linksys.lst was created with 20 entries.
# hydra -C ./dpl4hydra_linksys.lst -t 1 192.168.1.1 http-get /index.asp

  -x MIN:MAX:CHARSET  password bruteforce generation, type "-x -h" to get help
  -y        disable use of symbols in bruteforce, see above
  -r		 rainy mode for password generation (-x)

  -C FILE   colon separated "login:pass" format, instead of -L/-P options
  -M FILE   list of servers to attack, one entry per line, ':' to specify port
  -o FILE   write found login/password pairs to FILE instead of stdout
  -b FORMAT specify the format for the -o FILE: text(default), json, jsonv1

  service   the service to crack (see below for supported protocols)
  OPT       some service modules support additional input (-U for module help)

pw-inspector

A tool to reduce the password list

root@kali:~# pw-inspector -h
PW-Inspector v0.2 (c) 2005 by van Hauser / THC vh@thc.org [https://github.com/vanhauser-thc/thc-hydra]

Syntax: pw-inspector [-i FILE] [-o FILE] [-m MINLEN] [-M MAXLEN] [-c MINSETS] -l -u -n -p -s

Options:
  -i FILE    file to read passwords from (default: stdin)
  -o FILE    file to write valid passwords to (default: stdout)
  -m MINLEN  minimum length of a valid password
  -M MAXLEN  maximum length of a valid password
  -c MINSETS the minimum number of sets required (default: all given)
Sets:
  -l         lowcase characters (a,b,c,d, etc.)
  -u         upcase characters (A,B,C,D, etc.)
  -n         numbers (1,2,3,4, etc.)
  -p         printable characters (which are not -l/-n/-p, e.g. $,!,/,(,*, etc.)
  -s         special characters - all others not within the sets above

PW-Inspector reads passwords in and prints those which meet the requirements.
The return code is the number of valid passwords found, 0 if none was found.
Use for security: check passwords, if 0 is returned, reject password choice.
Use for hacking: trim your dictionary file to the pw requirements of the target.
Usage only allowed for legal purposes.
