Removable USB media devices such as flash drives are commonplace and convenient when it comes to sharing information – those tiny flash drives can hold a lot of data.
And, it turns out, a lot of malicious threats.
At industrials, USBs are often used by employees and contractors visiting sites to share and transfer files and update patches.
Our new research shows that they also pose a significant cybersecurity threat to industrial networks. While monitoring 50 industrial plants in the energy, oil and gas, chemical and paper and pulp industries across the world for cybersecurity threats through our new Secure Media Exchange (SMX) solution, we caught Stuxnet, Mirai and WannaCry lurking in the USB drives.
Here’s a sample of the findings:
44% detected and blocked at least one security issue
This confirms that USBs remain a significant vector for industrial threats. It has become easy for hackers to spread malware, ransomware attacks, steal confidential data and bring down production sites through USBs.
26% of those threats were major
These weren’t just blips – they could lead to significant disruption by causing operators to lose visibility or control of their operations.
15% of threats were high-profile and well-known
Odds are you’ve heard of these worms and viruses, including Stuxnet (2 percent), Mirai (6 percent), Triton (2 percent) and WannaCry (1 percent). They’ve existed for a long time and they were attempting to enter industrial facilities via removable storage devices in high density.
9% were designed to exploit USBs
Most of the malware detected were Trojans (55 percent), followed by bots (11 percent) and hacktools (6 percent).
And 9 percent were designed to directly exploit USB protocol and interface weaknesses, making them especially effective.

ABB has an extensive portfolio of eco-efficient solutions and services that can help decouple economic growth from environmental impacts. In fact, over half of ABB's worldwide revenues are generated by technologies that combat the causes of climate change. The company’s goal is to increase this contribution from 57 percent in 2018 to 60 percent by 2020.
FLIR Systems have released the FLIR VP40, a non-contact voltage detector for use in North America designed for field-troubleshooting and verification of residential, commercial, and industrial electrical installations. The VP40 makes it easy to quickly troubleshoot live and neutral wiring to ensure a safe job site.
Expanding on its extensive product line for motion control applications, Sensata Technologies recently released the Crydom DRMS Series hybrid motor starters.
