Locked SQL Injection Optimization and Obfuscation Techniques

[D4rkn3S]

Introduction

 

SQL Injections are without question one of the most dangerous web vulnerabilities around. With all of our information stored in databases, almost every detail about our lives is at the mercy of a simple HTTP request.

As a solution, many companies implement Web Application Firewalls and Intrusion Detection/Prevention Systems to try to protect themselves.

Unfortunately, these counter measures are not sufficient and can easily be circumvented.

This is all possible due to optimization and obfuscation techniques which have been perfected over the last 15 years since the discovery of this lethal vulnerabil

ity. Even though firewalls cannot not be relied on to prevent all attacks, some firewalls can be effective when used as a monitoring tool.

It is not unheard of for an attacker to be detected and blocked during mid-attack, due to firewall triggers and an alert security team. Because of this,

a SQL Injection that has been optimized and obfuscated has a much higher probability of being successful; it will extract the data faster and remain undetected for longer.

In this paper we will discuss and compare a variety of optimization methods which can be highly effective when exploiting Blind SQL Injections.

We will also introduce SQL queries which can be used to dump the whole database with just one request, making it an extremely easy to quickly retrieve data while going unnoticed.

Furthermore, we will be reviewing several obfuscation techniques wh

ich can make a SQL Injection unrecognizable to firewalls. When combined, these techniques create a deadly attack which can be devastating.
