The stevedores employed by Australian port operator DP World woke up this morning to a backlog of 30,000 shipping containers after the company was hit by a cyberattack on Friday. The maritime giant has resumed operations at all its facilities including container terminals in Melbourne, Sydney and Brisbane after Friday’s breach meant it had to disconnect the internet. It’s going to shift less than a quarter of standard daily volume today and it may take a week for the company to return to normal. DP World manages around 40 per cent of goods going in and out of Australia, making it a key point of failure. The government is planning new cyber security laws that would force companies to report all ransomware incidents. Industrial & Commercial Bank of China Ltd’s US unit was recently hit by a ransomware attack that meant some Treasury market trades had to be handled on a USB stick.
