sensor system. This is a passive device that detects an object simply by that object’s existence without generating any emissions that can be detected. This device is specifically designed to detect and track stealth aircraft missiles and satellites. This is a type of an esoteric field called anti-stealth technology. This technology has the ability to completely render current stealth technology applications and billions of dollars of stealth aircraft, missiles, and satellites totally obsolete. It not only detects and tracks the object, but also determines the object’s mass and Doppler velocity, which has an effect on the object’s orbital lifetime and other characteristics.

Pen Testing from a Mile Away

by Asim Zaman | 1047 words

Are you unimpressed with your wireless card’s range? Fed up with limited number of available access points? And like many other families in America, have a now unused satellite dish cluttering up your house? Constructing a Wi-Fi satellite dish can greatly extend your Wi-Fi range and open up many new interesting possibilities. During my time working as a help desk tech for an office building, I was eventually given the task of setting up their wireless network. With this came the penetration testing, to see how vulnerable they actually were. Now, here I faced the difficult task of wandering around the building trying to get in range of all the various access points due to my built-in wireless card’s pathetic range, all the while jumping from power plug to power plug due to my pathetic battery. This kind of job can be tiresome and can grow into an even worse problem when dealing with larger area projects such as college campuses or corporate parks. The Wi-Fi satellite dish allows you to cover a seemingly endless range with no movement whatsoever. The potential is infinite.

When beginning this project, you are going to want to gather up six different parts. Each is essential to the operation of the satellite dish.

The Dish: Any satellite dish will do, but it helps to have the antenna (the small pronged piece that extends out and resides in the hot spot of the satellite dish). A lot of times, dish networks will take back this piece, but you may get lucky and find a complete dish. Without the antenna, you will have to manually find the best spot to position your handmade receiver, which can be accomplished by a trial and error method.

The Wi-Fi Adapter: I recommend purchasing the Alpha Network's AWUS036H. This particular Wi-Fi USB adapter is equipped with several features that are much better than other models:

1. The chipset. This make and model contains the RTL8187 chipset, which is very compatible with aircrack and backtrack. This allows it to be ideal for pen testing.

2. The power output in this model is higher than that of other USB dongles in that it was built as a long range USB adapter. It therefore is capable of even further increasing your range.

3. The SMA male connector. This particular feature is essential for connecting the Wi-Fi module to the dish. This port is the segment where the antenna would normally attach.

The Cable: This cable needs to be the SMA female to N connector cable. By searching for this on Amazon or on Google, you can find one for a minimal price. I recommend getting one of six to twelve feet in length to give you plenty of maneuverability.

The following materials are used to create the satellite antenna.

Copper Wire: Simple enough.

Copper Flashing: A little expensive but still easy to find.
