Oftentimes after using Network Information Gathering, we are still left with a number of devices that may reflect an "Unknown" OS. With the saturation of these devices in the market today, there is a good chance there may be some located on your network.

In this installment, we’ll start diving into the anatomy of an Impact module where you'll get the opportunity to absorb some of the features and implications before we dive into building something real and useful. In the course of conducting penetration tests, we often come across password hashes of various types. We can sometimes use these without cracking them, but, it is often useful and necessary to crack those hashes. Why? You may ask.
