Mining Cybersecurity

The Mining Threat Landscape

The mining industry is undergoing a digital transformation that has fundamentally changed its cybersecurity risk profile. Modern mines operate fleets of autonomous haul trucks, remotely controlled drilling systems, and AI-driven ore processing optimization, all connected through industrial networks that span some of the most remote locations on the planet. This convergence of operational technology with digital systems creates an attack surface that is both vast and uniquely difficult to defend.

Ransomware attacks against mining companies have disrupted operations at some of the world's largest producers. When IT systems go down at a mine site, the impact cascades through production scheduling, fleet management, ore processing control, environmental monitoring, and safety systems. The financial impact of production stoppages can reach millions of dollars per day, making mining companies attractive targets for extortion.

Nation-state actors also target mining companies for economic espionage, seeking geological survey data, mineral reserve assessments, and bidding information for mining concessions. State-linked groups have targeted mining companies operating in strategically important mineral sectors including lithium, cobalt, rare earth elements, and uranium. The geopolitical significance of critical mineral supply chains has elevated mining cybersecurity from a business risk to a national security concern.

Compliance and Regulatory Requirements

Mining companies face a patchwork of cybersecurity and data protection requirements across the multiple jurisdictions where they typically operate.

• IEC 62443 — International standard for industrial automation and control system security, applicable to the SCADA systems, PLCs, and industrial networks that control mining operations from extraction through processing.
• ISO 27001 — International standard for information security management systems, increasingly required by mining joint venture partners, offtake agreement counterparties, and insurers as baseline security assurance.
• Critical Minerals Security Regulations — Emerging regulatory frameworks in Canada, Australia, and the EU establishing cybersecurity requirements for entities in critical mineral supply chains, driven by strategic competition for essential resources.
• Data Sovereignty Laws — Requirements in countries such as Indonesia, Chile, the DRC, and Kazakhstan that mandate mining operational data and geological data be stored within national borders or subject to specific cross-border transfer restrictions.
• Environmental Monitoring Regulations — Requirements for continuous, tamper-proof environmental monitoring data including tailings dam sensor readings, water quality measurements, and emissions data, where data integrity has both regulatory and safety implications.
• PIPEDA / Privacy Act (Canada) — Privacy requirements governing employee personal information at Canadian mining operations, including remote site worker data collected through biometric access systems and health monitoring.

Remote Operations Security

Mining operations in remote regions face distinct cybersecurity challenges. Connectivity often relies on satellite links (VSAT) or microwave backhaul with limited bandwidth, making cloud-based security tools impractical and real-time SOC monitoring difficult. Remote operations centres (ROCs) in urban locations control mine site equipment over these constrained links, creating a critical dependency on the availability and integrity of the communication infrastructure.

Mjolnir Security designs security architectures for bandwidth-constrained environments, implementing on-site log aggregation and analysis capabilities that can operate autonomously during connectivity outages while synchronizing with centralized SOC platforms when bandwidth permits. We assess the security of satellite communication systems, evaluate the resilience of ROC-to-site connectivity, and implement segmented network architectures that prevent a compromise at one mine site from propagating to others or to the corporate network.

Autonomous Equipment and OT Networks

Autonomous and semi-autonomous mining equipment including haul trucks, drill rigs, load-haul-dump machines, and conveyor systems are controlled through industrial networks where safety and cybersecurity intersect directly. A compromised autonomous haul truck weighing 400 tonnes represents a catastrophic safety risk. The command and control systems for these fleets must be protected against both external attacks and insider manipulation.

Our OT security assessments for mining environments cover the full stack from fleet management systems and mine automation platforms (such as Caterpillar MineStar, Komatsu FrontRunner, and Hitachi Wenco) down to the PLCs, RTUs, and communication protocols that control individual equipment. We evaluate the security of over-the-air firmware update mechanisms, GPS and positioning system integrity, and the isolation between autonomous equipment networks and other mine site systems.

Mjolnir's Mining Security Approach

Our mining practice is built on understanding the operational realities of the industry: remote locations, extreme environmental conditions, 24/7 production requirements, multi-jurisdictional operations, and the safety-critical nature of mining control systems. We deploy security solutions that work within these constraints rather than ignoring them.

We provide mining companies with security architectures designed for hybrid deployment across remote sites and corporate data centres, ensuring protection continues even when connectivity is degraded. Our threat intelligence capabilities monitor for threats specific to the mining sector, including nation-state espionage campaigns targeting critical mineral producers and ransomware groups known to target resource companies.

From OT security assessments at remote mine sites and autonomous equipment security reviews to enterprise SOC monitoring and incident response with fly-in capability, Mjolnir delivers cybersecurity that protects mining operations wherever they are located.
