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. By identifying these devices we can also potentially expand our attack surface and gain other useful information.

So, where do we start? We may as well create a new search folder so that only the machines that reflect "unknown" under the OS column can be viewed.
