Why manufacturing is the top ransomware target
The manufacturing sector's attractiveness to ransomware operators comes down to three structural characteristics that are unlikely to change.
Low tolerance for downtime, high motivation to pay
Manufacturers operate on thin margins and just-in-time delivery schedules. Every minute of unplanned downtime costs thousands of dollars. Attackers know this. A three-week production shutdown for a JIT manufacturer can lead to contract cancellations and permanent loss of customers, according to the Gartner® report. That economic pressure makes manufacturers more likely to pay extortion fees quickly rather than absorb weeks of lost production.
This is different from attacking a professional services firm or even a financial institution. Those organizations can often continue partial operations while recovering. A factory that cannot run its production line generates zero output and still carries full fixed costs.
Expanding attack surfaces from digital transformation
As factories implement Industry 4.0 programs, they are connecting decades-old machinery to each other, to enterprise IT systems, and to the internet. The Gartner® report identifies a specific vulnerability pattern: these connected systems often remain unpatched, unsegmented, and undermonitored, allowing attackers to pivot from IT networks to physical production controls.
The digital thread that connects manufacturing processes creates enormous operational value. But it also creates a continuous pathway that attackers can traverse from a compromised email account to a programmable logic controller (PLC) on the factory floor. Without proper network segmentation, a single phishing email can cascade into a production-stopping event.
Supplier dependencies as entry points
Modern manufacturing relies on complex vendor ecosystems. Every supplier with network access to a manufacturer's systems is a potential entry point. The Gartner® report notes that groups like Qilin weaponized trust relationships between vendors and factories during 2025, launching supply chain attacks that compromised manufacturers through their legitimate vendor connections.
For organizations managing supply chain risk at the project level, this adds a cybersecurity dimension to an already complex problem. It is no longer enough to track supplier delivery performance. PMO leaders need to understand the cybersecurity posture of every vendor with digital access to their systems.
The full cost of a manufacturing ransomware attack
The ransom itself is often a fraction of the total financial impact. The Gartner® report outlines several cost layers that accumulate after an attack.
Direct costs
Ransom payment: Average ransom demands in manufacturing have doubled to over $1.1 million.
Recovery costs: Sophos data puts the average at $1.53 million, covering incident response, forensic investigation, system restoration, and legal counsel.
Cyber insurance deductibles and premium increases: Manufacturing accounts for 33% of all cyber insurance claims, and premiums are projected to rise 15-20% in 2026.
Operational costs
Production downtime: Manufacturing environments require safety validation before restarting operations. Return to production cannot happen overnight. Downtime is often measured in weeks, not days.
Project delays: When production halts, every active manufacturing project in the portfolio is affected. NPI timelines slip, capital projects stall, and resource schedules cascade across the entire portfolio.
Customer impact: For JIT manufacturers, even a short production halt can trigger contract penalties, expediting costs, and customer defection.
Strategic costs
IP theft and competitive damage: Extortion-only attacks that steal proprietary designs without encrypting systems can destroy a company's long-term competitive position. If a competitor gains access to your CAD blueprints or manufacturing processes, the damage is permanent.
Regulatory penalties: The SEC's four-day disclosure rule and the EU's NIS2 Directive create legal exposure that adds to the financial burden. Companies that fail to report breaches promptly face fines on top of recovery costs.
Reputational damage: The Gartner® report cites the Jaguar Land Rover attack as an example where the impact extended well beyond the victim, affecting the U.K.'s GDP. When a major manufacturer is hit, customers, partners, and investors reassess the relationship.
What the Gartner® report recommends
The Gartner® report lays out a set of specific, practical actions for manufacturing leaders. These are not abstract principles. They are operational changes that can be implemented within existing governance structures.
Prioritize OT asset discovery and patching
Most manufacturers do not have a complete inventory of their operational technology assets. You cannot protect what you do not know you have. The report recommends deploying CPS protection platforms that can inventory assets and patch vulnerabilities without disrupting operations.
This is particularly relevant for organizations managing operational risk at the portfolio level. Adding OT asset visibility to the portfolio risk register transforms cybersecurity from an IT-only concern into a business-level priority that gets executive attention.
Implement strict network segmentation
The report calls for establishing a DMZ between corporate IT and plant floor networks. Industrial-grade firewalls should strictly limit traffic between zones. Cyber-physical systems should never have direct, unfettered internet access.
This recommendation reflects a basic architectural principle that many manufacturers have deferred: isolating production systems from enterprise systems so that a breach in one zone cannot cascade into the other. The challenges facing manufacturing projects today already include cybersecurity as a standing concern. Network segmentation is the most effective single action to contain blast radius.
Deploy immutable backups for production-critical data
Traditional backup strategies are not sufficient when attackers specifically target backup systems. The report recommends write-once-read-many (WORM) format backups that cannot be encrypted or deleted by attackers. Testing recovery procedures against physical production systems, not just email servers, is critical.
Secure remote access for third-party vendors
Vendor access to PLCs, SCADA systems, and other production controls needs dedicated secure remote access solutions. The report recommends auditing vendor access regularly and removing dormant accounts immediately. Every unused vendor account is a potential entry point.
Run incident response drills that include plant managers
IT-only incident response drills miss the reality of manufacturing cyber events. When a ransomware attack hits a production line, the plant manager needs to know how to manually operate or safely shut down machinery. Engineers need to understand recovery sequencing. The Gartner® report recommends including plant managers and engineers in incident response drills, not just IT staff.
Isolate supplier network connections
A breach in a supplier's network should not be able to move laterally into a manufacturer's production systems. The report recommends isolating supplier connections so that compromised vendor networks are contained before they reach critical systems.
