Houston Industrial Cybersecurity Threats: Key Findings from Honeywell’s 2025 Cyber Threat Report

The industrial cybersecurity environment continues to face unprecedented challenges, as revealed in Honeywell’s comprehensive 2025 Cyber Threat Report. Drawing from an analysis of 253.2 billion logs, 79.2 million scanned files, and 4,600 triaged events across global industrial environments, this report provides critical insights that every organization with operational technology (OT) should understand.

 Executive Summary: The State of Industrial Cyber Threats

The threat environment for industrial organizations has intensified dramatically during the reporting period from October 2024 to March 2025. Cybersecurity incidents have increasingly targeted operational technology environments, affecting everything from transportation systems to critical water infrastructure. What makes this particularly concerning is that 55% of self-reported cybersecurity incidents on SEC Form 8-Ks in 2024 were direct attacks on companies’ operational technology systems.

 Ransomware Dominance: A 46% Surge in Attacks

Perhaps the most alarming finding is the 46% increase in ransomware extortion incidents compared to the previous reporting period. The CL0P ransomware group has emerged as a dominant threat actor, surpassing other groups in activity levels. In the first quarter of 2025 alone, an additional 2,472 reported ransomware victims were documented, building on the 6,130 identified throughout 2024.

The financial impact is staggering. According to the Ransomwhere tracking system, over $1 billion in ransomware payments have been documented as of October 2024. Manufacturing, construction, healthcare, and technology companies have borne the brunt of these attacks, with agriculture and food production organizations seeing exponential increases in targeting.

 The Ramnit Banking Trojan: An Unexpected Industrial Threat

One of the most significant discoveries involves the W32.Worm.Ramnit malware, traditionally a banking sector trojan designed to steal account credentials. Honeywell’s analysis revealed a shocking 3,000% increase in Ramnit infections in Q4 2024 compared to its last documented appearance in Q2 2024. This malware accounted for 37% of all files blocked by Honeywell’s Secure Media Exchange (SMX) system during the reporting period.

The presence of banking trojans in industrial environments suggests threat actors are repurposing these tools to extract control system credentials. This represents a concerning evolution in attack methodology, where traditional IT-focused malware is being adapted for OT environments.

 USB and Removable Media: Persistent Attack Vectors

Physical security controls remain critical, as evidenced by the continued prevalence of USB-borne threats. Honeywell’s analysis identified several concerning trends:

• 25% of the top 10 security incidents involved USB plug-and-play events
• New worm families like Win32.Worm.Sohanad were discovered spreading via removable media
• Legacy vulnerabilities like CVE-2010-2568, notably used by Stuxnet, continue to be exploited through malicious shortcut files

The persistence of USB-based attacks underscores the importance of physical controls and media scanning protocols in industrial environments.

 Critical Infrastructure Under Fire

Government agencies have documented increasing threats to public services infrastructure. The Environmental Protection Agency reported that drinking water supplies for approximately 193 million Americans are vulnerable to cyberattacks. Meanwhile, the Transportation Security Administration has proposed new cybersecurity regulations for pipelines and railroads, mandating 24-hour incident reporting and annual cybersecurity evaluations.

Real-world incidents reinforce these concerns. A large U.S. water and wastewater utility serving 14 states experienced a breach that disrupted service to several key systems. Similarly, transit systems and airlines have faced ransomware and denial-of-service attacks that impacted operations and passenger services.

 The CL0P Ransomware Operation: A Deep Dive

The CL0P ransomware group, operated by the cybercriminal organization TA505, represents a sophisticated threat to industrial organizations. Active since at least 2014, TA505 operates as a ransomware-as-a-service (RaaS) provider while also functioning as an initial access broker and large-scale botnet operator.

CL0P’s attack methodology leverages numerous critical vulnerabilities, including flaws in Citrix, Windows, SolarWinds, Accellion, PaperCut, and Progress products. The group’s tactics demonstrate sophisticated reconnaissance and exploitation capabilities, often targeting software commonly used in enterprise and industrial environments.

 Regulatory Pressures and Compliance Challenges

The cybersecurity regulatory environment continues to evolve, adding compliance pressures to organizations already struggling with resource constraints. New SEC regulations requiring cybersecurity incident reporting have increased transparency but also highlighted the scope of attacks on operational technology.

The European Union Agency for Cybersecurity (ENISA) has emphasized the need for enhanced policy implementation, improved cyber crisis management, and strengthened supply chains across member states. These regulatory developments signal a global recognition of the critical nature of industrial cybersecurity.

 Emerging Attack Patterns and Sector Targeting

The report reveals concerning shifts in how cybercriminals target different sectors. Attacks on agriculture and food production have increased exponentially, while traditional targets like manufacturing and healthcare continue to face sustained pressure. This diversification suggests threat actors are expanding their targeting criteria to include sectors previously considered lower-priority.

The convergence of cyber and physical threats has become more pronounced, with attackers demonstrating increased sophistication in understanding industrial processes and their vulnerabilities. This evolution from opportunistic attacks to more targeted, industry-aware campaigns represents a significant escalation in threat sophistication.

 The Path Forward: Building Resilient Industrial Cybersecurity

The Honeywell report’s findings underscore the critical need for comprehensive, multi-layered cybersecurity strategies in industrial environments. Organizations must move beyond traditional IT security approaches to embrace solutions specifically designed for operational technology environments.

Key recommendations include implementing robust network segmentation, deploying specialized OT security monitoring tools, and establishing comprehensive incident response procedures tailored to industrial environments. The integration of AI-driven security technologies and cloud-native security controls offers promising avenues for enhancing defensive capabilities.

As threats continue to evolve and regulatory requirements expand, organizations must treat cybersecurity not as a cost center but as a fundamental operational requirement. The stakes are simply too high – and the adversaries too sophisticated – for anything less than a comprehensive, proactive approach to industrial cybersecurity.
