Cyber Threats Target Industrial Control Systems via Removable Media: Honeywell Report Reveals Growing Trend

Industrial control systems are increasingly becoming targets for cyber attacks, with cybercriminals adept at infiltrating these environments and staying hidden for extended periods. According to a report by Honeywell, malware transmitted via USB storage devices used to transfer files within and between industrial sites is a prime target for cyber threats.

The study highlights the growing trend of malicious software targeting removable media like USB devices, with attacks on these devices accounting for over half (51%) of total attacks in 2024. This represents a significant increase from the 9% reported in the previous 2019 report.

Cyber attackers are increasingly using sophisticated tactics to exploit vulnerabilities in operational technology (OT) environments, disrupting visibility, control, or causing system downtime. This has led to a rise in malware attacks specifically targeting industrial systems, with 31% of total malware attacks aimed at these systems and sites.

To combat this threat, it is crucial that OT environments enhance their cybersecurity measures. The report emphasizes the need for organizations to implement robust security protocols and monitor their networks closely to detect and prevent potential attacks before they can cause damage.
