A word on “ethical” password cracking
Regardless of the approach, the objective of this book is to help you with the tools and techniques you need to recover passwords, whether you are in a penetration test/red team operation, you are recovering a password of a user backup for someone who has unfortunately passed away, or anything in between.
The important caveat here is that this book focuses on ethical password cracking. The purpose of this book is not to help you circumvent laws or perform illegal activities. Rather, its purpose is to give you what you need to be successful in pointing out flaws in penetration testing engagements, or other approved means to enable your business.
Please ensure you consult with your legal counsel and/or company counsel before performing these techniques against passwords in your company.
