Task 1 Hydra Introduction


WHAT IS HYDRA?

Hydra is a brute force online password cracking program, a quick system login
password “hacking” tool.

Hydra can run through a list and “brute force” some authentication services.
Imagine trying to manually guess someone’s password on a particular service
(SSH, Web Application Form, FTP or SNMP) - we can use Hydra to run through a
password list and speed this process up for us, determining the correct
password.

According to its official repository, Hydra supports, i.e., has the ability to
brute force the following protocols: “Asterisk, AFP, Cisco AAA, Cisco auth,
Cisco enable, CVS, Firebird, FTP, HTTP-FORM-GET, HTTP-FORM-POST, HTTP-GET,
HTTP-HEAD, HTTP-POST, HTTP-PROXY, HTTPS-FORM-GET, HTTPS-FORM-POST, HTTPS-GET,
HTTPS-HEAD, HTTPS-POST, HTTP-Proxy, ICQ, IMAP, IRC, LDAP, MEMCACHED, MONGODB,
MS-SQL, MYSQL, NCP, NNTP, Oracle Listener, Oracle SID, Oracle, PC-Anywhere,
PCNFS, POP3, POSTGRES, Radmin, RDP, Rexec, Rlogin, Rsh, RTSP, SAP/R3, SIP, SMB,
SMTP, SMTP Enum, SNMP v1+v2+v3, SOCKS5, SSH (v1 and v2), SSHKEY, Subversion,
TeamSpeak (TS2), Telnet, VMware-Auth, VNC and XMPP.”

For more information on the options of each protocol in Hydra, you can check the
Kali Hydra tool page.

This shows the importance of using a strong password; if your password is
common, doesn’t contain special characters and is not above eight characters, it
will be prone to be guessed. A one-hundred-million-password list contains common
passwords, so when an out-of-the-box application uses an easy password to log
in, change it from the default! CCTV cameras and web frameworks often use
admin:password as the default login credentials, which is obviously not strong
enough.


INSTALLING HYDRA

Hydra is already installed on the AttackBox. You can access it by clicking on
the Start AttackBox button.

If you prefer to use the in-browser Kali machine, Hydra also comes
pre-installed, as is the case with all Kali distributions. You can access it by
selecting Use Kali Linux and clicking on Start Kali Linux button.

However, you can check its official repositories if you prefer to use another
Linux distribution. For instance, you can install Hydra on an Ubuntu or Fedora
system by executing apt install hydra or dnf install hydra. Furthermore, you can
download it from its official THC-Hydra repository.

Answer the questions below

Read the above and have Hydra at the ready.

Task 2 Using Hydra
Start Machine

Deploy the machine attached to this task, then navigate
to http://MACHINE_IP (this machine can take up to 3 minutes to boot)


HYDRA COMMANDS

The options we pass into Hydra depend on which service (protocol) we’re
attacking. For example, if we wanted to brute force FTP with the username being
user and a password list being passlist.txt, we’d use the following command:

hydra -l user -P passlist.txt ftp://MACHINE_IP

For this deployed machine, here are the commands to use Hydra on SSH and a web
form (POST method).


SSH

hydra -l <username> -P <full path to pass> MACHINE_IP -t 4 ssh

Option Description -l specifies the (SSH) username for login -P indicates a list
of passwords -t sets the number of threads to spawn

For example, hydra -l root -P passwords.txt MACHINE_IP -t 4 ssh will run with
the following arguments:

 * Hydra will use root as the username for ssh
 * It will try the passwords in the passwords.txt file
 * There will be four threads running in parallel as indicated by -t 4


POST WEB FORM

We can use Hydra to brute force web forms too. You must know which type of
request it is making; GET or POST methods are commonly used. You can use your
browser’s network tab (in developer tools) to see the request types or view the
source code.

sudo hydra <username> <wordlist> MACHINE_IP http-post-form
"<path>:<login_credentials>:<invalid_response>"

Option Description -l the username for (web form) login -P the password list to
use http-post-form the type of the form is POST <path> the login page URL, for
example, login.php <login_credentials> the username and password used to log in,
for example, username=^USER^&password=^PASS^ <invalid_response> part of the
response when the login fails -V verbose output for every attempt

Below is a more concrete example Hydra command to brute force a POST login form:

hydra -l <username> -P <wordlist> MACHINE_IP http-post-form
"/:username=^USER^&password=^PASS^:F=incorrect" -V

 * The login page is only /, i.e., the main IP address.
 * The username is the form field where the username is entered
 * The specified username(s) will replace ^USER^
 * The password is the form field where the password is entered
 * The provided passwords will be replacing ^PASS^
 * Finally, F=incorrect is a string that appears in the server reply when the
   login fails

You should now have enough information to put this to practice and brute force
your credentials to the deployed machine!
