  With the evolution of WCN (Wireless communication networks), the absolute
fulfillment of security occupies the fundamental concern. In view of security,
we have identified another research direction based on the attenuation impact
of rain in WCN. An approach is initiated by an eavesdropper in which a secure
communication environment is degraded by generating Artificial Rain (AR), which
creates an abatement in the secrecy rate, and the cybersecurity gets
compromised. By doing so, an attacking scenario is perceived, in which an
intruder models a Half-Duplex (HD) attack. Half-Duplex specifies the attack on
the downlink instead of targeting both uplink and downlink. This allows the
attacker to alleviate the miss-rate of the attacking attempts. The layout for
the HD attack is explained using RRC (Radio Resource Control)-setup. Further,
we have determined and examined the performance parameters such as secrecy
rate, energy efficiency, miss-rate, sensitivity in the presence of AR. Further
comparison of rural and urban scenarios in the presence and absence of AR is
carried out concerning the variation in secrecy rate with respect to the
millimeter-wave frequencies and distance. Lastly, the methodology of the HD
attack is simulated, revealing that the HD attack maintains a low miss rate
with improved performance as compared to the performance and miss-rate attained
by the full-duplex attack
