Cyber crime is not something that is just about to come to shipping — it is already here.

An organised gang hacked computers in the Port of Antwerp for two years to divert containers laden with drugs, guns and money from South America before the crime was spotted and stopped; malware was used to tilt an oil rig working off Africa; North Korea has blocked the global positioning satellite (GPS) signals to ships in the Port of Incheon; and a disgruntled employee used malware on a USB stick to disrupt a US oil refinery.
