Traffic Alert and Collision Avoidance System II Spoofing Vulnerability

A vulnerability exists in the Traffic Alert and Collision Avoidance System (TCAS) II) standard, specifically in versions 7.1 and prior. This vulnerability allows for the transmission of radio frequency signals with fake location data to aircraft, creating the illusion of non-existent aircraft on radar displays. Such spoofing can disrupt normal operations by triggering false Resolution Advisories, which are critical for maintaining safe distances between aircraft.

Impact

Exploitation of this vulnerability can manipulate aircraft displays to show fake targets, potentially causing undesired Resolution Advisories, which could disrupt normal flight operations and safety protocols.
