YAMUGAG-20 Exploder is a Radio Frequency (RF)-based wireless exploder system designed and constructed specially for the Nigerian Air Force (NAF) to overcome the challenges associated with the existing wired exploders used for the disposal of unserviceable ordnances. The Exploder system has three main parts namely, the master transmitter unit, the master receiver/slave transmitter unit, and the slave receiver unit. Each of these units is made up of transceiver module, microcomputer and power source. The microcomputers were programmed using C and C++ programming language of the Integrated Development Environment (IDE) software. The exploder is portable and easy to operate. For a typical demolition exercise, the operation of the exploder is such that signals are relayed from the master transmitter unit to the master receiver/slave transmitter unit onto the slave receiver unit to initiate an electric detonator leading to the detonation of the unserviceable ordnances. Functionality, range, power consumption, and system reliability tests were conducted on the exploder to establish its performance and efficiency. The results obtained from the tests indicated that the exploder transmitting at a frequency of 2.4GHz performed satisfactorily up to a range of 1000 meters. Therefore, the exploder has the potential of not only meeting the demolition demands of the NAF but can also be applied for other nonmilitary purposes like mining and related activities.

In recent years, increase in the development of connected and autonomous vehicles (CAVs) has sparked cyber security concerns. In particular, vehicle-to-everything (V2X) communication, which is essential for CAV and the transportation system, has introduced a new threat landscape and created several attack surfaces for malicious agents. The available literature on cyber-attacks mostly concentrate on sophisticated tools and equipment in performing malicious activities. However, ignorance of simple attack and defense methods, sometimes as simple as defining proper access policies, is among top reasons for cyber-attacks. This paper aims to emphasize on the need for practicing security-bydesign and increase awareness of manufacturers and developers to adopt minimum security measures. A generic network communication vulnerability assessment method is adopted to perform navigational attack through GPS falsification on connected vehicles, using an Unmanned Ground Vehicles (UGV) as a case study. This paper underlines the Wi-Fi security threats if used for V2X communication without proper access control measures in place. The experimental analysis demonstrates exploitation of a vulnerability which allows full control and backend navigation manipulation with respect to the UGV movement.
