DP World – a major shipping company – has sprung a leak with a cybersecurity breach on Friday, forcing it to suspend operations. Details on what hackers have targeted and who’s behind it have not been revealed, but its effects are enormous. DP World manages about 40% of Australia’s maritime freight, and reports say that the shutdown across ports in Sydney, Melbourne, Perth, and Brisbane could last for days. Already, 30,000 containers have been prevented from moving, taking up about 90% of DP World’s storage space at the ports. Home Affairs Minister Clare O’Neil said the framework developed after the Medibank and Optus hacks had been activated to enable the company to coordinate with the government. If you’re waiting on something, don’t bother emailing DP World with questions – it has shut down its internet to stop “any ongoing unauthorised access”.
