Cybersecurity in Mining: Protecting Geological Data, Payments, and Operations

Mining teams run on data and attackers know it. Exploration IP (targets, drill results, models), payments
(vendors, payroll, fuel, logistics), and operations (plants, comms, fleet systems) are all valuable.
The risk is not only “someone steals files.” The real damage is downtime, extortion, and fraudulent payments
that are hard to reverse.

This article focuses on practical steps you can implement without turning your team into a full-time IT shop.
The goal is simple: protect exploration IP, reduce payment fraud, and make ransomware far less likely to stop
your work.

The three attack paths that hit mining hardest

A) Phishing and business email compromise (BEC)

Attackers target finance and project leads with convincing emails: invoice changes, “updated bank details,”
urgent wire requests, or fake data-room invites. If your email is compromised, the attacker can sit silently,
learn your workflows, then strike at the perfect moment.

B) Ransomware and data extortion

Modern ransomware is rarely “encrypt and leave.” It is “steal first, then encrypt, then pressure you with
deadlines.” Mining is a prime target because downtime is expensive and reputational risk is high.

C) Operational disruption (OT and site systems)

Plants and remote sites depend on operational technology (OT): control systems, remote access tools, and
sensors. When IT and OT are tangled together, one breach can cascade from office devices to site operations.

Protecting geological and exploration IP (the data room problem)

Exploration data is uniquely sensitive because it is also the asset. If a third party gets your targeting
thesis early, the value leakage is permanent.

Do this first: classify your files

• Tier 1 (core IP): targets, drill databases, models, resource interpretations, valuation assumptions.
• Tier 2 (sensitive): contracts, land access, permitting, vendor quotes, payroll, legal docs.
• Tier 3 (shareable): published reports, public announcements, marketing content.

Data-room rules that actually reduce risk

• Least privilege: only share what a person needs, not what is “nice to have.”
• Short expiry: time-limit access and review weekly, not yearly.
• View-first: prefer view-only and watermarking for high-value PDFs.
• Separate rooms: one for investors/JV, one for contractors, one internal.
• Audit trails: require logs of who accessed what and when.

If your current “data room” is a shared folder with broad permissions, treat it as a risk exposure and fix it.
This is one of the highest ROI security upgrades in mining.

Access control: the fastest win is identity

Most breaches start with credentials. If you fix identity, you remove a huge percentage of easy attacks.

Non-negotiables

• MFA everywhere: email, VPN, accounting, cloud storage, data rooms.
• Separate admin accounts: no one should browse the web with admin rights.
• Strong offboarding: disable accounts the same day someone leaves.
• Privileged access control: limit who can change permissions and payment workflows.

If you can only do one thing this month: enforce MFA on email and cloud storage. That is where most real-world
compromises begin.

Ransomware resilience: make “restore” boring

Ransomware is less scary when you can restore fast. The teams that survive it best are not the ones with the
fanciest tools. They are the ones that practiced recovery.

Practical defenses

• Backups that cannot be encrypted: immutable or offline copies.
• 3-2-1 logic: multiple copies, different media, one copy offsite.
• Test restores: if you have never restored, you do not have backups.
• Patch the obvious: keep VPN, remote access, and endpoints current.
• Segment your network: do not let one laptop reach everything.

OT security: keep office IT problems away from plant reality

OT has different constraints: uptime, safety, and vendor dependencies. The goal is not to “install an agent on
everything.” The goal is to reduce remote access risk and limit blast radius.

What works in real sites

• Inventory: know what OT assets exist and who owns them.
• Network segmentation: IT and OT should not be one flat network.
• Controlled remote access: use a jump box, MFA, and time-limited access.
• Logging and monitoring: you cannot defend what you cannot see.
• Change discipline: document changes, especially vendor changes.

Standards like ISA/IEC 62443 and OT guidance like NIST SP 800-82 exist for a reason: they reflect what breaks in
industrial environments when IT-style assumptions are applied blindly.

Vendor risk: the quiet way attackers get inside

Mining relies on vendors: drilling contractors, labs, ERP providers, survey teams, OT integrators, consultants.
If a vendor gets compromised, your access path is compromised.

Minimum vendor checklist (use this in procurement)

• MFA required for any access to your systems.
• Named accounts (no shared logins), plus logging.
• Clear incident notification timeline (hours, not days).
• Vulnerability and patch process (who updates what, how fast).
• Access is time-boxed and removed when the job ends.
• Contracts include security responsibilities and audit rights where appropriate.

Payment security: stop invoice fraud before it happens

Payment fraud is brutally simple: attackers change bank details. The fix is also simple, but it requires
process discipline.

Controls that prevent real losses

• Call-back verification: bank detail changes must be confirmed by phone using a known number.
• Two-person approval: no single person can approve a new payee and release funds.
• Vendor onboarding rules: require formal documentation, not email-only changes.
• Payment alerts: notify finance leads for large or unusual transfers.

A simple roadmap (30 days, 90 days)

In 30 days

• Enable MFA on email, cloud storage, and finance tools.
• Lock down the data room: least privilege, expiry, logs.
• Implement payment change verification rules.
• Verify backups and perform one test restore.

In 90 days

• Segment IT and OT networks (at minimum, separate access paths).
• Deploy basic endpoint protection and patch discipline.
• Formalize vendor access: named accounts, MFA, time-limited access.
• Create a short incident response plan (who calls whom, what gets isolated first).

Closing thought

Cybersecurity in mining is not about perfection. It is about removing the easy wins attackers rely on:
weak identity, flat networks, uncontrolled sharing, and sloppy payment processes.
If you harden those, you dramatically reduce your operational risk.
