What happened

On 2023-11-10 (10 November 2023) DP World Australia detected unauthorised access to its Australian corporate network and disconnected that network from the internet, which stopped landside operations at its container terminals in Melbourne, Sydney, Brisbane and Fremantle. The operator handles about 40 percent of Australian container freight, and the National Cyber Security Coordinator said the interruption would affect the movement of goods into and out of the country for a number of days. Operations restarted on 2023-11-13 (13 November 2023), and the company said the resumption did not mean the incident had concluded. DP World Australia reported on 2023-11-28 that it had cleared a backlog of 30,137 containers by 2023-11-20, that no ransomware was found, and that a small amount of data had been taken.
