How To Start Penetration Testing by Web Application Hacking.

Hello Guys,

Being a hacker is exciting but it is more of Responsible task.
To start learning new things, you must be aware of what's going on in background while hacking foreground.
So,To enrich your Tech-hunger and learn hacking,This is a step toward being Hacker.

Anyways Let's go to Core Part,

Today , we 're going to learn about Web Application Hacking.


As per Wikipedia.org ,

Web Application:

A web application is an application that is accessed over a network such as the Internet or an intranet. The term may also mean a computer software application that is coded in a browser-supported language (such as JavaScript, combined with a browser-rendered markup language like HTML) and reliant on a common web browser to render the application executable."

There are several projects which helps to learn and provide sample hacking application for Techno-geek and Penetration Testers,Among them;These are several projects which can be found helpful.

• Gruyere (live) -- http://google-gruyere.appspot.com/
  
• FreeBank Online(live) -- http://zero.webappsecurity.com/
  
• Crack Me Bank (live) -- http://crackme.cenzic.com/
  
• Acunetix Acublog -- http://testaspnet.vulnweb.com (registration required)
  
• Hacme Tools -- http://www.foundstone.com/us/resources/proddesc/
  

• WebGoat -- http://www.owasp.org/index.php/OWASP_WebGoat_Project

These tools provide in-built Web-Server and Framework to test hacking application.

For a newbie,I would recommend "WebGoat" or "Acuentix".

WebGoat is built upon Java framework,So to install it requires JRE (Java Runtime Environment)has built-in Apache Tomcat Web-Server installed.

It provides several attack systems like SQL Injection,XSS (cross site scripting) attack practice,Firewall Bypassing,Man in The Middle Attack etc.
It provides deep information regarding Web Application and Its Security features.These feature makes it unique,

1. It has buit in Web Server
2. It provides Solution along with Problem
3. It is Open source Software.
4. It provides source of framework along with application.
5. It gives hints whenever some difficulty occur with one click

To install WebGoat,I would recommend using Virtual OS by VMware Or Virtual box as it makes our OS tremendously vulnerable to attack.
 
Download:

For Virtual Sessions :

1) Virtual Box : www.virtualbox.org

or

2) VMware : www.vmware.com

  
So,Its end of post.Meet you guys next time.Till then Have safe hacking and Bring endeavor to satisfy your Techno-lust.

For Query,Post a Comment.

Boost Your Internet

Friends,First Of All I wanna make sure that,This Work is not mine.
I got it by hacking someone's PC.And thought it would be useful to anyone,That's why I've posted here.
So Let's start...

----------------------------------------------------------------------------------
                       These settings allow you to boost the speed of your broadband Internet connection when using a Cable Modem or DSL Router with Windows 2000 and Windows XP.

1) Open your registry and find the key below.

Create the following DWORD values, as most of these values will not already exist you will need to create them by clicking on 'Edit -> New -> DWORD Value' and then set the value as shown below.

DefaultTTL = "80" hex (or 128 decimal)
Specifies the default time to live (TTL) for TCP/IP packets. The default is 32.

EnablePMTUBHDetect = "0"
Specifies whether the stack will attempt to detect Maximum Transmission Unit (MTU) routers that do not send back ICMP fragmentation-needed messages. The default is 0.

EnablePMTUDiscovery = "1"
Specifies whether the TCP/IP stack will attempt to perform path MTU discovery as specified in RFC 1191. The default is 1.

GlobalMaxTcpWindowSize = "7FFF" hex (or 32767 decimal)
Specifies the system maximum receive window size advertised by the TCP/IP stack.

TcpMaxDupAcks = "2"
Determines the number of duplicate ACKs(Aknowledgement packets) that must be received for the same sequence number of sent data before "fast retransmit" is triggered.

SackOpts = "1"
Enables support for selective acknowledgements as documented by Request for Comment (RFC) 2018. Default is 0.

Tcp1323Opts = "1"
Controls RFC 1323 time stamps and window scaling options. Possible values are: "0" = disable RFC 1323 options, "1" = window scale enabled only, "2" = time stamps enabled only and "3" = both options enabled.

TcpWindowSize = "7FFF" hex (or 32767 decimal)
Specifies the receive window size advertised by the TCP/IP stack. If you have a latent network you can try increasing the value to 93440, 186880, or 372300.

Exit your registry and restart Windows for the changes to take effect.

If you don’t want to edit the registry, here's a little TCP utility that is ideal...

Have Fun Hacking.
I'll post as many as I can.But I'll have to halt as some work is  comin' up.
But going by promising to catch ya all later for sure.
So,Meet you guyz later.

Hacking Basics

Guys,To start with hacking website or a server,you'll require some skill that helps to write your own code.

• First of all, to start hacking.

You'll need a target website.Once you’ve got it, add it for Pinging
[For that,you have to follow these steps(In Windows).
1) Start - Run - cmd
2) type ping "your target website(without quote)"
3) copy that ip address]

• Now, we need to gather information about the website.You have to to Whois lookup.That will gather all information about server.

Go to

http://whois.domaintools.com

& add IP or the website.You’ll see a large amount of information about the website.
Use Google to find even more information about the website.

After all mess up,

• Open Nmap(A tool to hack/get info of online).
  Once you have done that,
   "ip_address nmap –sT –sV"(without quote) in Nmap’s command bar & scan website.]Once done,observe O.S.(Operating System), Ports, Services running on the website server.

• Once done, you’ll need to find banner of the software.
  [Banner: It shows the software & version running on ports.]
  It may chage depending on the OS of server.
  
  • For WIN VISTA & 7:

You need to download & Open Netcat.
[Because Telnet is disabled in WIN VISTA & 7]

Once done type, nc
Ex: nc 127.0.0.1 21
It will show banner with all information.

• For other OS:

Open Telnet[Start > RUN > telnet]

Once done type, O
Ex: O 127.0.0.1 21
Once you’ve done that, you’ll get a banner.
This will be displaying all the details of the software running on port.
If this doesn’t work you can try the first method.

Once you’ve got the banner, you need to search for vulnerability matching with banner.

• Exploit databases:

Injector_____http://www.inj3ct0r.com/
Milw0rm_____http://www.milw0rm.com
Security Focus_____http://www.securityfocus.com
Osvdb_____http://www.osvdb.org
Cve Mitre_____http://cve.mitre.org
Metasploit_____http://www.metasploit.com

More info:http://www.hackforum.net

Once you’ve got the matching exploit of the same version software.
[If you haven’t got, try another port.]
You need to edit values, compile & run it.

Most common exploit Coders:

• Perl

For perl exploits, Copy the exploit in notepad & save it with .pl extension.
Download & Install, Active Perl:

 http://www.activestate.com/activeperl

Once done, edit the exploit with notepad & double click to run it.

• PHP

For PHP exploits, copy & save it in .php extension.
Download & Install WAMP:


http://www.wampserver.com/en/

Once done, edit the exploit with notepad & execute it from CMD.

• Python

For python exploits, copy & save it in .py extension.
Download & Install python:


http://www.python.org/download

Once done, edit the exploit with notepad & double click to run it.

• C/C++

For C/C++ exploits, copy & save it in notepad.
Download & Install Blood Shed. (Google the link)
Once done, edit the exploit, compile & double click to run it.

If your exploit is successful you will get access to server,
You’ll be able to edit every part of the website.
If your exploit wasn’t successful try with different port, services & software.
You can also use Metasploit web to search exploits.

Fundamentals Of Networking

IP Address:It is an address provided to every computer or nod in network by ISP(Internet Service Provider) to connect to using internet.In VPN(Virtual Private Network ),it may have been provided by server.

Domain Name System (DNS): This allows IP address to be translated to words. It is easier for human being to remember character.
E-mail addresses are also converted by DNS in character or string.

For example, it is much easier for anyone to remember address "facebook.com" than to remember 69.63.189.63.

Dynamic IP Address: One that is not static or other word changing.It is given by your ISP or DHCP(Dynamic Host Configuration Protocol) Server.
Computer will get this number as it logs on to the network and saves you the trouble of having to know details regarding the specific network configurations.
This number can be assigned to anyone using a dial-up connection, Wireless and High Speed Internet(i.e DSL,TSL Cable) connections.

Static IP Address: One that is fixed and never changes.
Most ISP's can offer to assign a single static IP for Some more rupees(or your currency).

IPv4: It is being used by most devices.However,IPv4 IPs are running out quickly.
IPv4 is limited to 4,294,967,296 IPs.

IPv5: This is an experimental protocol for UNIX based systems. In keeping with standard UNIX release conventions, all odd-numbered versions are considered experimental. It was never intended to be used by the general public.

IPv6: The replacement for IPv4.
The estimated number of unique IPs for IPv6 is (340,282,366,920,938,463,463,374,607,431,768,211,456)(Count how many no. are there???!! lolzz) or Base(2)mentisa(128).


If you need any kind of help.Just make sure you comment and publish it.
Have Fun Hacking.
