Key Takeaways
- Manufacturing is the most targeted industry for cyberattacks due to its critical role in global supply chains, low tolerance for downtime, rapid adoption of connected technologies, and historically underfunded security programs.
- Ransomware drives over 90% of total financial losses despite representing only 12% of claims, with losses highly concentrated in a few severe incidents; misconfigured multi-factor authentication (MFA) alone accounts for approximately 26% of total losses, including the largest single event.
- The most expensive incidents stem primarily from preventable control failures, not missing controls; targeted, evidence-based measures like auditing MFA deployment, strengthening vulnerability management, and implementing financial transfer controls significantly reduce exposure.
- Resilience identifies six high-impact controls consistently reducing financial exposure: validating MFA, enhancing vulnerability management for external systems, implementing procedural financial controls, extending security to supply chains, quantifying cyber risk, and focusing on ransomware containment.
- Transfer fraud and email compromise (driven by phishing) are the most frequent claim types (~30% of incidents) but yield lower individual payouts; ransomware remains the dominant financial threat, necessitating strong IT/OT segmentation, ransomware-specific EDR, and tested backups.
- Translating cyber risk into financial terms via quantification and insurance is critical for informed board-level decisions, linking specific failures (like MFA misconfig or unpatched software) to measurable loss reduction and investment prioritization.
Manufacturing’s Elevated Cyber Risk Profile
Resilience’s analysis of nearly five years of cyber insurance claims confirms manufacturing as the most targeted industry for cyberattacks. This heightened risk stems from the sector’s indispensable position within global supply chains, where operational downtime carries exceptionally high costs, creating strong incentives for attackers seeking disruptive impact or large payouts. The rapid proliferation of connected Industrial Internet of Things (IIoT) devices on factory floors has significantly expanded the attack surface, while historical underinvestment in cybersecurity programs relative to operational technology (OT) priorities has left critical vulnerabilities unaddressed. This combination of high-value targets, increasing digital exposure, and security gaps makes manufacturing particularly attractive to sophisticated threat actors aiming for maximum financial or operational disruption.
Financial Impact: Ransomware’s Disproportionate Burden
The financial consequences of cyber incidents in manufacturing are heavily skewed toward ransomware attacks. Although ransomware represents only about 12% of the total number of claims filed, it accounts for over 90% of the aggregate financial losses documented in Resilience’s dataset. This stark disparity reveals that losses are not evenly distributed; instead, a small number of exceptionally severe ransomware incidents drive the overwhelming majority of the sector’s financial exposure. In contrast, more frequent but less severe events—such as phishing attempts and transfer fraud (collectively representing roughly 30% of claims)—generate lower average payouts per incident, underscoring the critical need for manufacturers to prioritize defenses against high-impact, low-frequency threats like ransomware while still addressing more common vulnerabilities.
Root Cause: Preventable Control Failures Drive Major Losses
A crucial finding from Resilience’s claims analysis is that the most financially damaging incidents are primarily caused by preventable failures in existing security controls, rather than the complete absence of those controls. Misconfigured multi-factor authentication (MFA) emerges as the single most significant point of failure, directly contributing to approximately 26% of total financial losses. This includes the largest individual ransomware incident captured in the dataset. The data demonstrates that while MFA or other controls may be deployed, gaps in implementation—such as improper configuration, inconsistent enforcement across user accounts, or failure to maintain conditional access policies—render them ineffective. This highlights that effective cybersecurity requires not just adopting technologies, but rigorously validating, auditing, and maintaining their proper operation to eliminate exploitable bypass conditions.
Control Priority 1: Validating and Auditing MFA Deployment
Resilience emphasizes that simply deploying MFA is insufficient; continuous auditing and validation are essential to ensure it delivers its intended protection. This involves verifying consistent enforcement across all user accounts (including privileged and service accounts), identifying and eliminating potential bypass mechanisms (like legacy authentication protocols or misconfigured fallback options), and confirming that conditional access policies are correctly tailored to the organization’s risk profile and properly integrated with identity systems. By treating MFA validation as an ongoing operational process rather than a one-time setup task, manufacturers can close the critical gap that currently allows attackers to exploit misconfigured authentication as a primary entry point for devastating ransomware campaigns, directly addressing the control failure responsible for over a quarter of total losses.
Control Priority 2: Strengthening Vulnerability Management for External Systems
Proactively managing vulnerabilities in systems exposed to the internet is identified as another critical control for mitigating the most costly ransomware outcomes. Resilience’s data links unpatched or flawed software on external-facing assets directly to a significant proportion of high-severity ransomware incidents, accounting for roughly 13% of total losses. The report acknowledges the unique challenges posed by Operational Technology (OT) environments, where traditional patching may be disruptive or infeasible due to legacy systems or process criticality. In such cases, organizations are urged to implement compensating controls: network segmentation to isolate vulnerable OT assets, virtual patching solutions that mitigate risks without altering core systems, and enhanced, continuous monitoring for signs of exploitation targeting these weak points. This targeted approach reduces the attack surface exploitable by ransomware groups seeking initial access through known vulnerabilities.
Control Priority 3: Procedural Controls for Financial Transfers
To combat the frequent (though less costly per incident) threats of phishing and transfer fraud—which together constitute about 30% of claims—Resilience stresses the necessity of robust procedural controls governing financial transactions. These attacks often begin with compromised email accounts used to send fraudulent payment requests. Effective defenses include mandating out-of-band verification (e.g., a phone call to a known contact) for any changes to vendor payment details, enforcing dual authorization requirements for large or unusual financial transfers, and providing targeted, regular training for finance and accounts payable teams on recognizing sophisticated social engineering tactics. Notably, the average transfer fraud event costs approximately ten times more than the average business email compromise (BEC) incident, making these procedural safeguards not only a security imperative but also a significant cost-saving measure by preventing high-value financial scams before funds are diverted.
Control Priority 4: Extending Security Requirements to the Supply Chain
Vendor and supply chain vulnerabilities represent a distinct and significant source of loss in manufacturing cyber insurance claims, prompting Resilience to advocate for extending security rigor beyond the organization’s immediate boundaries. Manufacturers should enforce baseline security requirements on critical suppliers and partners, particularly mandating the implementation and validation of MFA and timely patching for systems interacting with the manufacturer’s networks or data. Continuous monitoring of vendor risk posture—through assessments, questionnaires, or third-party risk management platforms—is essential to detect degradation in a supplier’s security health. Furthermore, developing and testing contingency plans for disruptions caused by a key supplier’s cyber incident ensures business resilience. This proactive supply chain focus addresses a systemic risk pathway where weaknesses in downstream partners can directly compromise the manufacturer’s own operations and data integrity.
Cyber Risk Quantification and Insurance as Strategic Tools
Resilience underscores the vital role of cyber risk quantification and strategic insurance use in transforming technical cybersecurity concerns into actionable financial insights for executive leadership and boards. By analyzing claims data, the report makes tangible connections between specific technical failures and financial outcomes: demonstrating how MFA misconfiguration drives a quarter of losses, how unpatched software enables costly ransomware, and how procedural gaps enable fraud. This evidence-based linkage allows security leaders to prioritize investments where they will yield the greatest reduction in expected financial loss. Coupled with appropriate cyber insurance coverage—structured to transfer residual risk after optimally implementing preventive controls—quantification provides a common language (financial impact) that facilitates informed budgeting decisions, justified security spending, and aligned risk management strategies between technical teams, the CFO, and the boardroom.
Conclusion: Focused Action on Evidence-Based Priorities
The Resilience report delivers a clear, data-driven roadmap for manufacturing security leaders aiming to mitigate their disproportionate cyber risk. It moves beyond generic advice, pinpointing a small set of high-impact, evidence-based priorities derived directly from the analysis of real-world claims and threat intelligence. The core message is unambiguous: significant reductions in financial exposure are achievable not through theoretical perfection or unlimited spending, but through disciplined focus on validating critical controls like MFA, hardening external-facing systems against exploitation, instituting strong financial transaction protocols, securing the extended supply chain, preparing for ransomware with detection and recovery capabilities, and consistently framing cyber risk in financial terms to guide strategy. By concentrating resources on these specific, preventable failure points—particularly the pervasive issue of misconfigured MFA—manufacturers can substantially strengthen their resilience against the evolving threat landscape targeting their critical operations.
