Still no ransom - DP World Aust boss yet to hear from hackers as port operator goes back online

This time yesterday the port operator DP World was reeling from a cyberattack that left around 30-thousand shipping containers stranded in the critical leadup to Christmas. Although DP World's operations are now back online, the company's Australian boss still doesn't know how the hackers got in, or whether they took any private data - and he's told the ABC there's been no ransom demand so far.
