FBI Warning: Oil & Gas Field Control Systems May Be Exposed to Cyber Attacks

If you operate wells, production facilities, or field control systems, this matters.

A newly released FBI advisory warns that threat actors are actively targeting oil and gas PLC systems, SCADA networks, and field automation — the same technology used across operators, field operators, and oil & gas service companies.

This isn’t a traditional IT issue.

This is oil and gas operational technology security, and it directly impacts production uptime, field operations, and revenue.

When oil and gas field control systems are exposed, attackers may be able to disrupt production, modify automation, or take wells offline.

What’s being targeted in oil and gas environments

The advisory highlights attacks targeting oil and gas SCADA systems, PLCs, and remote field automation commonly used in upstream production.

These include:

• Well control PLCs

• Artificial lift controllers

• Tank battery automation

• SCADA-connected production equipment

• Remote telemetry units (RTUs)

• Compressor control systems

• Internet-exposed field devices

• Remote well monitoring systems

• Vendor remote access connections

These systems are widely deployed across oil and gas operators, field operators, and O&G service companies managing remote sites.

What this means for production operations

A cyber incident involving oil and gas field automation can quickly turn into operational disruption:

• Wells going offline

• Artificial lift shutdown

• Tank battery automation failure

• Compression systems stopping

• Remote site visibility lost

• SCADA alarms disabled

• Dispatching field crews

• Production reporting gaps

This leads directly to:

• Production downtime

• Loss of daily revenue

• Increased lease operating expense (LOE)

• Emergency field visits

• Higher operating costs

• Operational risk

• Safety exposure

Even short disruptions in upstream oil and gas production can impact barrels, gas volumes, and trucking schedules.

Why many oil and gas operators are exposed

Many oil and gas operational technology environments were not originally designed with cybersecurity in mind.

We commonly see:

• Internet-exposed PLCs in the field

• Remote access added for vendor support

• Default passwords still active

• No segmentation between IT and SCADA networks

• Remote well monitoring exposed to the internet

• No logging of controller changes

• Shared credentials across sites

• No monitoring of oilfield automation systems

This is extremely common across:

• Independent oil and gas operators

• Private E&P companies

• Field operators

• Artificial lift providers

• Automation companies

• Measurement companies

• Compressor service companies

Quick reality check for operators

Would you know if:

• A well control PLC was modified remotely?

• Artificial lift settings were changed?

• A compressor controller was shut down?

• Tank battery alarms were disabled?

• Remote well monitoring stopped reporting?

• Someone accessed your SCADA system?

Most oil and gas operators would not.

That’s why oil and gas cybersecurity for field control systems is becoming a major operational concern.

What operators should check immediately

To reduce oil and gas production downtime risk, start with:

• Remove direct internet access to PLCs

• Secure remote vendor access

• Change default controller credentials

• Segment SCADA and business networks

• Monitor controller and automation changes

• Audit remote field devices

• Review exposed cellular and radio connections

These steps significantly improve oil and gas operational technology security.
