Australia’s Cyber Security Coordinator says the Australian government is working with seaport terminal operator DP World Australia to resolve what he calls a serious and ongoing “nationally significant cyber incident.” Air Marshal Darren Goldie released a statement on November 12, 2023, two days after unidentified hackers breached DP World Australia’s cyber defences. The state-owned Dubai-based multinational stevedoring company handles around 10% of the world’s container traffic and 40% of Australia’s container traffic, including those passing through Melbourne, Sydney, Brisbane and Fremantle ports. DP World Australia cut off internet access on November 10 in a bid to thwart the attack. In the process, it shut down its Australian port operations and halted the movement of a reported 30,000 containers. While DP World Australia has not yet disclosed the nature of the attack or what data was stolen, it is known that the breach affected systems that managed the transfer of containers between ships and trucks. Some limited operations were beginning to occur on November 12.
