| contents | The emergence of movable antenna (MA) technology has marked a significant advancement in the field of wireless communication research, paving the way for enhanced connectivity, improved signal quality, and adaptability across diverse environments. By allowing antennas to adjust positions dynamically within a finite area at transceivers, this technology enables more favourable channel conditions, optimizing performance across applications like mobile telecommunications and remote sensing. However, throughout history, the introduction of every new technology has presented opportunities for misuse by malicious individuals. Just as MAs can enhance connectivity, they may also be exploited for disruptive purposes such as jamming. In this paper, we examine the impact of an MA-enhanced jamming system equipped with $M$ antennas in a downlink multi-user communication scenario, where a base station (BS) with $N$ antennas transmits data to $K$ single-antenna users. Simulation results show that an adversary equipped with MAs reduce the system sum rate by $30\%$ more effectively than fixed-position antennas (FPAs). Additionally, MAs increase the outage probability by $25\%$ over FPAs, leading to a $20\%$ increase in the number of users experiencing outages. The highlighted risks posed by unauthorized use of this technology, underscore the urgent need for effective regulations and countermeasures to ensure its secure application. |
