Becoming the Hacker

By: Adrian Pruteanu

Overview of this book

Becoming the Hacker will teach you how to approach web penetration testing with an attacker's mindset. While testing web applications for performance is common, the ever-changing threat landscape makes security testing much more difficult for the defender. There are many web application tools that claim to provide a complete survey and defense against potential threats, but they must be analyzed in line with the security needs of each web application or service. We must understand how an attacker approaches a web application and the implications of breaching its defenses. Through the first part of the book, Adrian Pruteanu walks you through commonly encountered vulnerabilities and how to take advantage of them to achieve your goal. The latter part of the book shifts gears and puts the newly learned techniques into practice, going over scenarios where the target may be a popular content management system or a containerized application and its network. Becoming the Hacker is a clear guide to web application security from an attacker's point of view, from which both sides can benefit.

The confirmation


Now that the cloud server is properly configured to record incoming requests over DNS, we can go back to our earlier example and leverage the cloud to confirm the vulnerability out-of-band.

You'll recall that the vulnerable application allows unsanitized input to be executed on the SQL server via the name parameter. The challenge we sometimes face, as attackers, is the difficulty in confirming the existence of this type of vulnerability when the application does not behave differently based on the input given. Sometimes, we may even be lucky enough to examine source code, in which case we'd just skip right to exploiting the vulnerability.

The WAITFOR DELAY payload will work for most blind SQL injections, as the majority of application views depend on the result from SQL queries that the controller executes.

SELECT * FROM users WHERE user = 'Dade';WAITFOR DELAY '0:0:20' --';

In the surprisingly common scenario where the vulnerable query is executed asynchronously and the page...
