Finland’s Transport and Communications Agency, Traficom, has issued a public announcement informing of an unusual spike in GPS interference near the country’s eastern border.
According to reports, the interference isn’t limited to Finland but also affects Poland, Lithuania, Latvia, and the broader Baltic region.
This spoofing is relatively easy because the actual GPS signal is weak. There are very cheap short distancr GPS jammers. The cheapest equipment required to perform GPS spoofing attacks costs a couple of hundred USD (for example HackRF One and computer), while the software to simulate realistic GPS satellite radio signals is generally widely available. Please note that disturbing GPS signals is illegal in very many countries.
