AB  - Low Earth Orbit (LEO) satellite communications have become one of the key technologies for future 6G non-terrestrial networks due to their global connectivity and low latency. However, frequent handovers in LEO satellite networks could initiate severe security threats. In this paper, we investigate the feasibility of the impersonation attack by a fake base station, which hijacks the legitimate handover between a satellite and a ground base station. Further, we analyze a handover failure probability and discuss potential countermeasures to enhance the security of the LEO satellite handover procedure.
