Introduction:
As the world continues its march toward digitization, the industrial sector remains a tempting target for cybercriminals. A new Q1 2025 report by Kaspersky ICS CERT paints a worrying picture of how industrial control systems (ICS) are still grappling with vulnerabilities despite widespread awareness. The most notable revelation? The internet continues to be the most common entry point for cyberattacks in industrial environments. While some regions have shown resilience, others remain dangerously exposed. This highlights the urgent need for industrial organizations to rethink their cybersecurity frameworks before attackers exploit systemic weaknesses even further.
Global Cyber Threat Landscape for ICS in Q1 2025: A 40-Line Recap
Kaspersky’s latest findings highlight that internet-based threats remain the most significant cyber risk facing Industrial Control Systems globally. Across the board, 21.9% of ICS computers had malicious activity blocked, indicating persistent and widespread vulnerability. The internet topped all other infection sources, with malicious websites, cloud services, messengers, and CDNs acting as major conduits for attacks. Regional disparities were stark. Africa saw 12.76% of ICS systems exposed to internet threats, followed by Southeast Asia at 12.32% and South Asia at 10.83%. Even highly developed Northern Europe was not immune, reporting a 5.24% exposure rate.
These threats often involved denylisted URLs, phishing scripts, cryptominers, spyware, and malicious scripts. A key contributor to this vulnerability was the poor segmentation between operational technology (OT) and IT networks. Without sufficient security barriers, ICS endpoints gained unsafe access to external systems. Email remained the second most common attack vector, especially through phishing campaigns containing malicious attachments. Regions such as Southern Europe (6.76%), the Middle East (5.17%), and Latin America (4.55%) were especially hard hit. In contrast, Russia experienced the lowest email threat rate at just 0.88%.
Removable media such as USB drives, while on the decline, still posed a risk—particularly in Africa, where 2.44% of ICS computers were affected, nearly five times the global average. Malware types were categorized by function: initial infection tools (e.g., malicious links and scripts), next-stage malware (e.g., spyware and ransomware), and self-propagating software like worms and viruses. Cryptojacking within ICS environments is also rising. Attackers are using both online miners and executable files that initiate PowerShell-driven, fileless malware. These attacks evade traditional antivirus systems and highlight increasing threat sophistication.
Spyware is especially rampant in Africa and Southern Europe and is often used to steal credentials, exfiltrate data, or pave the way for ransomware. Ransomware activity was most pronounced in East Asia, the Middle East, and Africa. Regional threat levels align with the degree of cyber readiness. High-risk areas often lack funding, foundational cybersecurity policies, and sufficient OT network architecture. Meanwhile, places like Western Europe, Northern Europe, Australia, and New Zealand report much lower threat activity, thanks to tighter OT-IT segmentation and mature cybersecurity ecosystems.
Ultimately, the Q1 2025 report emphasizes that internet connectivity is a persistent weak spot in industrial systems. Organizations are urged to adopt stronger network segmentation, restrict internet privileges for OT devices, implement multi-layered defenses, and train personnel continuously. As cybercriminals grow bolder and more sophisticated, proactive strategies must replace reactive approaches. The stakes are rising, and without robust defenses, industrial operations worldwide remain exposed to serious disruption.
What Undercode Say:
The Q1 2025 data uncovers not just a technical problem, but a structural and strategic one. The dominance of the internet as a threat vector reflects the broader issue of weak integration between OT and IT systems in industrial sectors. The report’s statistics make it clear: more than 1 in 5 ICS computers globally are being targeted with malicious content. That’s not a small glitch — it’s an epidemic.
Regions such as Africa and Southeast Asia are disproportionately affected. This correlates strongly with fast-paced industrial growth that outpaces the cybersecurity infrastructure being implemented. These regions often suffer from low investment in secure OT environments, limited staff training, and minimal compliance to international security protocols. Yet, even advanced regions like Northern Europe aren’t immune, which reinforces the idea that no one is entirely safe without continuous adaptation.
Email-based threats still thrive due to human error, and that makes awareness training a cornerstone of cybersecurity. Southern Europe and Latin America demonstrate how phishing attacks remain successful where there’s an overreliance on traditional security tools. In contrast, Russia’s exceptionally low rate of email-based infection is likely due to stricter perimeter controls and more advanced filtering systems.
The rise in fileless malware such as those triggered by PowerShell scripts is alarming. These threats can bypass traditional antivirus software completely, making them harder to detect and neutralize. It’s no longer just about installing an antivirus and hoping for the best — adaptive defense strategies are essential. These include behavioral analysis, endpoint detection and response (EDR), and intrusion detection systems (IDS) specifically designed for ICS environments.
Another area of concern is the increasing use of spyware. Often underestimated, spyware serves as both an information-gathering tool and a precursor to more devastating ransomware attacks. In Africa and Southern Europe, its prevalence reveals the dual function of such malware — to probe weaknesses and strike when ready.
Cryptojacking in ICS systems might not seem like the biggest concern at first glance, but it diverts system resources and introduces instability into critical processes. It also often signals that attackers already have access to your systems, which is a red flag in any industrial environment.
Ransomware continues to pose an existential threat to industries. Once it infiltrates a network, it can bring production lines to a halt, cause millions in damages, and even endanger human safety if critical infrastructure is affected.
What’s clear is that attackers are becoming more intelligent and targeted. They’re adapting their techniques for specific ICS vulnerabilities. The industrial world must do the same — by adopting zero-trust architectures, implementing strict access controls, and most importantly, promoting a culture of cyber hygiene from the factory floor to the control room.
Governments and regulatory bodies need to step in as well. Standardized cybersecurity frameworks for industrial systems should be mandated globally. These regulations can help ensure that even smaller industrial players are maintaining minimum security baselines.
The future of industrial security lies in layered, intelligence-driven defense systems. It’s not just about tools, it’s about the strategy behind them — threat modeling, predictive analytics, and real-time response capabilities. Without them, the gap between attacker and defender will only widen.
Fact Checker Results ✅🛡️
Is the internet still the leading vector for ICS attacks? Yes ✅
Do certain regions show higher vulnerability due to lack of cybersecurity investment? Yes ✅
Are email and removable media still relevant threats in 2025? Yes ✅
Prediction 🔮📊
Given the growing reliance on connected systems in industrial operations, internet-borne threats are likely to intensify. Fileless attacks will increase, driven by advanced scripting techniques and the use of legitimate tools for malicious purposes. Regions with inadequate cybersecurity frameworks will continue to be prime targets unless rapid investments are made. Expect global ICS cybersecurity to pivot heavily toward behavior-based monitoring, stricter internet access policies, and machine learning-driven anomaly detection by mid-2026.
