Cara Hack Website Dengan Telnet Windows Command
A password is technically defined as secret string of characters used to authenticate or gain access to resources. It must be kept in secret and hiden from others who are not allowed to access those resources. Passwords have been used with computers since the earliest days of computing. One of the first time sharing systems, was introduced in 1961. It had a login command that requested a user password. After typing “PASSWORD”, the system turns off the printing mechanism, if possible, so that the user may type in his password with privacy.
Flupe definition. The strength of a password is a function of length, complexity, and unpredictability. It measures the effectiveness in resisting of guessing or breaking it. Weak passwords, on the other hand shorten the time necessary to guess and gain access to personal/corporate e-mails, sensitive data like financial info, business info, credit cards, etc.
There are many ways a password can be weak corresponding to the strengths power of various attack schemes. The most popular of this kind of credential attack is, brute force. it is a trial and error method like guessing, attempt to decode encrypted data such password or data encryption used by application program or “hacking tool”.
The high-end particle systems available include fire, smoke, bubbles and others. Real-time 3D graphics. You can even add realistic motion blur to moving objects and make or import 3D models.KEY FEATURES INCLUDE:.
Hydra is the fastest network logon cracker which supports numerous attack protocols. It is very fast and flexible, and new modules are easy to add. This tool makes it possible for researchers and security consultants to show how easy it would be to gain unauthorized access to a system remotely. Hydra was written by van Hauser and its additionally supported by David Maciejak. In the latest update hydra development is moved to public github repository at : https://github.com/vanhauser-thc/thc-hydra.

That was a brief simple introduction to hydra. Now lets move onto installation.
INSTALLING HYDRA
Hydra is pre-installed on kali linux, however if you have a different operating system you could compile and install it on your system. Currently, hydra’s support on different platforms:
- All UNIX platforms (Linux, *bsd, Solaris, etc.)
- MacOS (basically a BSD clone)
- Windows with Cygwin (both IPv4 and IPv6)
- Mobile systems based on Linux, MacOS or QNX (e.g. Android, iPhone, Blackberry 10, Zaurus, iPaq)
To download, configure, compile and install hydra, just type into terminal:
If you have Ubuntu/Debian you will need some dependency libraries:
If you could not find those libraries in your repository, then you need to download and install them manually.
HOW TO USE HYDRA
Congratulation, now you have succeeded to install hydra on your system. Actually, Hydra comes with two flavors, GUI-gtk and my favorite, CLI version. and in addition hydra has also CLI guided version, its called “hydra-wizard”. You will be guided step by step instead of typing all the commands or arguments manually into the terminal. To run hydra, from your terminal type :
For CLI :
For CLI-wizard :
For GUI :
After you type ‘hydra’ it will display help commands like this:
Bruteforce web based login with hydra
Hydra supports some bruteforcing service as i mentioned earlier, one of them is used to bruteforce web based logins such as, social media login form, user banking login form, your router web based login, etc. That “http[s]-{get post}-form” which will handle this request. In this tutorial i am going to show you how to bruteforce vulnerable web logins. Before we fire up hydra we should know some needed arguments such below:
- Target : http://testasp.vulnweb.com/Login.asp?RetURL=%2FDefault%2Easp%3F
- Login username : admin (if you don’t sure, bruteforce this)
- Password list : “The location of dictionary file list containing possible passwords.”
- Form parameters : “for general, use tamper data or proxy to obtain form of request parameters. But here im using iceweasel, firefox based, network developer toolbar.”
- Service module : http-post-form
Obtaining post parameters using browser, iceweasel/firefox
In your firefox browser press keys ‘CTRL + SHIFT + Q‘. Then open the web login page http://testasp.vulnweb.com/Login.asp?RetURL=%2FDefault%2Easp%3F, you will notice some text appear on the network developer tab. It tells you what files are transfered to us. See the method all are GET, since we have not POST any data yet.
To obtain the post-form parameters, type whatever in the username and or password form. You will notice a new POST method on the network developer tab. Double click on that line, on the “Headers” tab click “Edit and Resend” button on right-side. On the Request Body copy the last line, such as “tfUName=asu&tfUPass=raimu”. the “tfUName” and “tfUPass” are parameters we need. As seen below:
Kali linux has bunch of wordlists, choose the appropriate wordlist or just use rockyou.txt place in /usr/share/wordlists/ as seen below:
Alright, now we got all arguments we need and ready to fire up hydra. Here is the command pattern:
Let’s break down the commands:
- l <username> : is a word containing username account, use -L <FILE> to refer list of possible user name in a file.
- P <FILE> : is a file list of possible password, use -p <password> to literally use one word password instead of guess it.
- testapp.vunlwebapp.com : is a hostname or target
- http-post-form : is the service module we use
- “/Login.asp?RetURL=%2FDefault%2Easp%3F:tfUName=^USER^&tfUPass=^PASS^:S=logout” = the 3 parameters needed, the syntax is :
{page URL}:{Request post body form parameters}:S={Find whatever in the page after succesfully logged in} - v = Verbose mode
- V = show login:pass for each attempt
- f = Terminate program if pair login:password is found
Now lets let hydra try to break the password for us, it needs time since it is a dictionary attack. Once you succeded finding a pair of login:password hydra will immediately terminate the job and show the valid credential.
There is so much that hydra could do, since in this tutorial we just learned how to bruteforce web based logon using hydra, we only learn one protocol, that is http-post-form protocol. We can also use hydra against another protocol such ssh, ftp, telnet, VNC, proxy, etc.
