The smart mining systems have become vulnerable to cyber attacks due to the inclusion of industrial control systems, Internet of Things technology, and cloud computing platforms at remote locations that are usually left unguarded. With all the systems being digitized in mines, such as haul-truck operations and plant controls, a cyber breach can result in physical harm, loss of production, and even environmental harm.
Ransomware and supply chain hacks are two of the most potentially disruptive threats, ransomware by disrupting the ability to operate OT assets through encryption, and the latter by giving threat actors entry into these OT networks via compromised vendors or software updates. The state-sponsored and industrial espionage threat actors are also known to compromise mining companies’ exploration, grade modeling, and process control intellectual property.
Older PLCs, SCADA systems, and sensors may not have been built for the current level of cybersecurity and might not incorporate encryption, authentication, or even patching capabilities. On the other hand, new devices like smart IoT drills and haulers present many more opportunities for endpoint security issues such as configuration mistakes, default passwords, or even physical manipulation.
Attacks on smart mine systems could exploit set points, alarms, or interlocks leading to equipment damage or malfunction, failure of conveyors, and even a lack of monitoring toxic gases, which would pose immediate safety risks. The interference in drilling, crushing, or dewatering systems would prevent multi-million-dollar machinery from being utilized and lead to increased downtime, especially in countries where mining is an important revenue source for exports.
The regulators and insurers have made cybersecurity a vital necessity by introducing requirements like risk assessments, asset inventory, and incident response planning, especially those which are designed for OT systems. Standards like NIST CSF, ISO 27001, and national standards (ASD Essential Eight) are gaining prominence within contracts and licenses, thereby encouraging miners to improve network segmentation, use multi-factor authentication, and restrict third-party access.
A holistic strategy should involve OT-aware monitoring, continuous vulnerability assessment, and strict change management instead of treating mines as generic IT facilities. Industry-specific guidelines suggest implementing strict network segmentation in order to separate IT and OT, monitor anomalies in control traffic, update systems regularly, and train staff against phishing and social engineering, which may facilitate even greater incidents.
