A series of newly revealed attacks on the shipping industry have highlighted the growing risk to the sector in cyberspace.

In one, a commercial ship on contract to the US military was the target of an intrusion by suspected Chinese military hackers.

Another incident saw a major fuel supplier fall victim to an $18m scam as the bunkers sector faces growing cybercrime threats.

A report released in recent weeks by the US Senate’s Armed Services Committee found some 50 successful intrusions or “other cyber events” on US Transportation Command (Transcom) contractors in the 12 months ending on 30 May 2013.
