In the ever-evolving world of cybersecurity, it’s easy to get caught up in the latest hacking trends and sophisticated zero-day exploits. But while those headlines grab attention, a surprising truth lurks beneath the surface: industrial operational technology (OT) systems remain vulnerable to surprisingly simple attack methods.

The Low-Tech Threat to High-Tech Systems

Recent reports highlight a concerning trend – hackers are increasingly targeting OT systems with basic tools like USB drives, exploiting known vulnerabilities, and deploying tried-and-true malware. While these tactics may seem outdated compared to the flashier exploits, their effectiveness shouldn’t be underestimated.

Here’s why these “low-tech” methods continue to pose a significant threat:

• The Air Gap Fallacy: Many OT systems exist in a perceived state of isolation, disconnected from the internet for security reasons. However, this “air gap” can be bridged by physical access. An infected USB drive plugged into an unsuspecting machine can become the bridgehead for an attack.
• Legacy Systems: Many OT systems are built on aging infrastructure. Patching and updating these systems can be challenging due to compatibility issues or fears of disrupting critical operations. This leaves them vulnerable to known vulnerabilities that have readily available exploits.
• Human Error: Social engineering tactics and a lack of cybersecurity awareness training can leave even the most secure systems exposed. A convincing email luring an employee to click a malicious link or insert a compromised USB drive can be all it takes to compromise an entire system.

Defending Your OT Systems: It’s Not Just About the Latest Threats

While staying informed about new cyber threats is essential, a robust OT security strategy shouldn’t neglect the basics. Here’s what you can do to harden your defenses against these persistent low-tech attacks:

• Strict USB Policy: Implement a strict policy regarding the use of external storage devices. Restrict access, require security scans, and educate employees on the risks associated with USB drives.
• Patch Management: Prioritize regular updates and patching for all OT systems. Conduct thorough testing before deploying patches to minimize disruption.
• Cybersecurity Awareness Training: Educate your workforce on social engineering tactics and best practices for cyber hygiene.
