CNN on 3rd July carried an article about the risks of cybercrime affecting superyachts and a former navigation systems expert with the German military who became obsessed with defending yachts from malicious hacking. The article provides an example where one billionaire had more than $150,000 stolen when yacht hackers pilfered his bank account. Navigation systems have also been reportedly locked and held for ransom. A number of superyachts even feature financial dealing rooms with data-rich Bloomberg terminals, necessitating strong firewalls.
