Construction firm reports 30 to 40 intrusion attempts by hackers everyday.
Shipbuilders bidding to construct the next generation of submarines for the Royal Australian Navy are reporting multiple hacking attempts with the German firm ThyssenKrupp saying there are 30 to 40 intrusion attempts every day.
All parties have declined to formally point the finger at one specific party, but rumours suggest that most attacks come from Russian and Chinese sources.
According to current estimations, the subs will be delivered to the Australian Royal Navy by mid-2020s.
There is no evidence the hacks have been successful, but the number of attempts is forcing the companies to hand-deliver the most sensitive information to ensure its safety.
