The Threat Landscape for Australian Transport & Logistics
What the sector is up against:
The DP World Australia incident of November 2023 remains the most publicly visible demonstration of what a cyberattack on transport infrastructure actually costs. When the port operator disconnected its systems in response to unauthorised network access, trucks could not move containers in or out of terminals in Sydney, Melbourne, Brisbane and Fremantle. Approximately 30,000 containers — including refrigerated cargo holding perishable goods — were stranded for three days. The Australian Federal Police and ASD’s ACSC treated it as a nationally significant incident, activating the National Coordination Mechanism. DP World manages roughly 40 percent of goods entering and leaving Australia; the disruption did not merely affect a single operator. It affected the national supply chain.
This incident was not an anomaly. ASD’s Annual Cyber Threat Report 2023–24 identified transport, postal and warehousing as the third most frequently reported critical infrastructure sector for cyber incidents, accounting for 15 percent of all critical infrastructure reports. By FY2024–25, critical infrastructure as a whole represented 13 percent of all incidents responded to by ASD’s ACSC — up from 11 percent the prior year — with denial-of-service attacks against critical infrastructure increasing by 280 percent. In May 2025, ASD joined international partners in highlighting an active Russian state-sponsored cyber campaign explicitly targeting Western logistics entities and technology companies involved in the coordination, transport and delivery of freight. The campaign was not hypothetical or generic. It named logistics as a priority target.
Why transport and logistics is targeted:
The structural vulnerabilities of the sector are well understood by threat actors. Transport and logistics operators run hybrid IT/OT environments where network compromise has immediate physical consequences: warehouse automation halts, tracking and telemetry systems go dark, and fleet management platforms become inaccessible. Unlike a data breach affecting a financial services firm, a logistics cyber incident does not require data exfiltration to cause severe damage — the disruption itself is the leverage. For ransomware groups, this makes logistics operators attractive targets: the pressure to restore operations quickly creates incentive to pay. For state-sponsored actors, the ability to degrade national supply chains has strategic value independent of financial gain.
The sector also carries significant data value. Freight operators manage customs documentation, bills of lading, hazardous material manifests, personnel records and client commercial data across interconnected systems that extend into supply-chain partner networks, shipping lines and government agencies. Third-party and supply-chain risk is consequently a significant exposure vector — an entry point that the ASIC’s own 2023 cyber resilience review identified as undermanaged across many Australian organisations, noting that nearly half of respondents were not adequately managing third-party or supply-chain risk.
The IT/OT convergence reality:
The technology environment of a modern Australian logistics operator looks nothing like a standard enterprise IT estate. A major freight or port operator typically runs warehouse management systems (WMS), transport management systems (TMS), fleet telematics platforms, cargo tracking and visibility tools, and warehouse automation equipment — all of which increasingly depend on network connectivity to function. At the same time, that environment includes operational technology: cranes, conveyor systems, automated guided vehicles, building management systems, CCTV and access control, and environmental monitoring. These systems were designed for operational reliability, not network security. Many were never intended to be networked at all.
As IT and OT networks converge — driven by efficiency gains from real-time data integration and the operational intelligence it enables — the attack surface expands. OT systems that once operated in air-gapped environments are now connected, either to corporate networks or directly to the internet for remote monitoring. Patching cycles that work in IT (deploy within days of a vendor release) are often impractical in OT (a two-year maintenance window is not unusual). Legacy control systems may be running unsupported operating systems with no available security updates. The result is an environment where modern cyber threats encounter infrastructure that was not designed to resist them. The Transport Security Amendment (Security of Australia’s Transport Sector) Act 2025, which received Royal Assent in March 2025, explicitly recognises this shift — introducing an all-hazards approach to transport security that goes beyond physical access control to encompass cyber threats, supply-chain dependencies and insider risk.
Distributed networks and the connectivity challenge:
Transport and logistics is inherently a distributed sector. A freight operator may manage depots across multiple states, each with different network infrastructure, different operational technology, and different levels of IT capability. A third-party logistics provider might operate out of a combination of company-owned and client-site facilities. Port operators contend with physical environments that are challenging for wireless coverage and require highly reliable connectivity for crane operations, vehicle tracking and cargo processing. Mobile workforces — drivers, warehouse staff, yard operators — depend on connectivity that is both performant and secure.
The challenge of maintaining consistent security standards, network performance and operational visibility across this distributed, heterogeneous environment is significant. Many operators are still running networks built for the operational requirements of a decade ago, before warehouse automation, IoT device proliferation and cloud-native logistics platforms transformed their IT architecture. The gap between current infrastructure and what is needed to support both modern operations and modern security is, in many cases, substantial.
