Cyber-Attack Drone Payload Development and Geolocation via Directional Antennae

The increasing capabilities of commercial drones have led to blossoming drone usage in private sector industries ranging from agriculture to mining to cinema. Commercial drones have made amazing improvements in flight time, flight distance, and payload weight. These same features also offer a unique and unprecedented commodity for wireless hackers -- the ability to gain ‘physical’ proximity to a target without personally having to be anywhere near it. This capability is called Remote Physical Proximity (RPP). By their nature, wireless devices are largely susceptible to sniffing and injection attacks, but only if the attacker can interact with the device via physical proximity. A properly outfitted drone can increase the attack surface with RPP (adding a range of over 7 km using off-the-shelf drones), allowing full interactivity with wireless targets while the attacker can remain distant and hidden. Combined with the novel approach of using a directional antenna, these drones could also provide the means to collect targeted geolocation information of wireless devices from long distances passively, which is of significant value from an offensive cyberwarfare standpoint. This research develops skypie, a software and hardware framework designed for performing remote, directional drone-based collections. The prototype is inexpensive, lightweight, and totally independent of drone architecture, meaning it can be strapped to most medium to large commercial drones. The prototype effectively simulates the type of device that could be built by a motivated threat actor, and the development process evaluates strengths and shortcoming posed by these devices. This research also experimentally evaluates the ability of a drone-based attack system to track its targets by passively sniffing Wi-Fi signals from distances of 300 and 600 meters using a directional antenna. Additionally, it identifies collection techniques and processing algorithms for minimizing geolocation errors. Results show geolocation via 802.11 emissions (Wi-Fi) using a portable directional antenna is possible, but difficult to achieve the accuracy that GPS delivers (errors less than 5 m with 95% confidence). This research shows that geolocation predictions of a target cell phone acting as a Wi-Fi access point in a field from 300 m away is accurate within 70.1 m from 300 m away and within 76 meters from 600 m away. Three of the four main tests exceed the hypothesized geolocation error of 15% of the sensor-to-target distance, with tests 300 m away averaging 25.5% and tests 600 m away averaging at 34%. Improvements in bearing prediction are needed to reduce error to more tolerable quantities, and this thesis discusses several recommendations to do so. This research ultimately assists in developing operational drone-borne cyber-attack and reconnaissance capabilities, identifying limitations, and enlightening the public of countermeasures to mitigate the privacy threats posed by the inevitable rise of the cyber-attack drone

The vast extent of pelagic deposits, covering about 70 per cent of the ocean floor, thus about half of the earth, makes them of obvious importance to all Earth Science. All the pelagic (eupelagic) sediments, whether largely of plankton remains or fine inorganic particles, have certain distinctive characteristics to reflect their environment of accumulation. The great segregation of manganese in pelagic sediments presents many problems. It is hypothesized that in the formation of present day nodules a relatively slow accumulation in order to permit deposition of more of the manganese as large nodules, rather than as the disseminated micronodules that are in larger proportion in the Tertiary

Observation of manganese deposits made during the 1936 transect of C/S Lord Kelvin through the Northern Atlantic Ocean

In May and June 1936 Dr. C. S. Piggot of the Geophysical Laboratory, Carnegie Institution of Washington, took a series of 11 deep-sea cores in the North Atlantic Ocean between the Newfoundland banks and the banks off the Irish coast. These cores were taken from the Western Union Telegraph Co.'s cable ship Lord Kelvin with the explosive type of sounding device which Dr. Piggot designed. All but two of these cores (Nos. 8 and 11) are more than 2.43 meters (8 feet) long, and all contain ample material for study. Of the two short cores, No. 8 was taken from the top of the Faraday Hills, as that part of the mid-Atlantic ridge is known, where the material is closely packed and more sandy and consequently more resistant; No. 11 came from a locality where the apparatus apparently landed on volcanic rock that may be part of a submarine lava flow

Annotated record of the detailed examination of Mn deposits of the Eniwetok Atoll

Some short cores from the shelf at about 800-1000 fathoms on the southwest flank of Eniwetok Atoll penetrated Pliocene deposits with little to no later sediment cover. The Quaternary deposits include much coarse reef debris, particularly the fragments of algae such as Halimeda and other shallow-water material up to several millimeters in grain size, mixed with varying amounts of pelagic Foraminifera. The Pliocene sediments (one may be upper Miocene) are pure pelagic deposits of much finer grain size, consisting of coccoliths and pelagic Foraminifera with no admixture of reef material. Bottom photographs show areas of well-developed ripple marks in coarse sediment (C. J. Shipek, manuscript) apparently formed only in the areas with the veneer of post-Tertiary coarse sediments. A brown impregnation at the top and extending down as mottling for a few centimeters is also usual in the Tertiary sediment of the cores. This seems to consist of iron and manganese oxides and adds somewhat to the induration
