Well, we are now seeing a return of archaic technology, with shipping firms looking to using LORAN to deal with potential GPS hacks:
Digitalization, wireless networks, and the Internet of Things (IOT) have allowed the 21st century supply chain to achieve levels of efficiency and visibility that were unimaginable a generation ago. But sometimes that progress comes at a price. For instance, in June, logistics professionals around the globe discovered that for all its benefits, that hyperconnectivity also opened up new vulnerabilities when the “Petya” ransomware attack crippled operations at shipping giant Maersk Line.
Now, some ocean carriers are turning to an old-school remedy to reduce their exposure to certain cyber attacks. Out of concern that hackers could jam the global positioning system (GPS) signals used by cargo ships to navigate, several nations are considering replacing modern satellite-based systems with legacy World War II-era radio technology, according to Reuters.
LORAN first saw service in the 2nd World War.
This is seriously old school, and I am seriously amused.
