1. A method comprising:
obtaining one or more location-reporting signals of a maritime vessel, wherein the one or more location-reporting signals comprise one or more respective sets of geographical coordinates, each of which having a timestamp;
determining that the one or more location-reporting signals are at least partially fabricated, wherein said determining is based on identifying a contradiction between a content of the one or more location-reporting signals and external data, wherein the external data comprises information derived from location-reporting signals received from entities external to the maritime vessel, wherein the entities comprise, at least, other maritime vessels; and
in response to said determining, performing a responsive action, wherein the responsive action is configured to perform:
verifying or refuting a determination of a potential location fabrication event based on said determining, wherein said verifying or refuting is performed by analyzing images depicting the one or more respective sets of geographical coordinates during a period of their timestamps, wherein the potential location fabrication event is verified in case the images do not depict objects that can represent the maritime vessel; and
mitigating a risk from the potential location fabrication event by disassociating from the maritime vessel.
