Ransomware in manufacturing is on the rise. This trend has widespread consequences for organizations, including operational disruption, data compromise, safety risks, financial losses, and long-term reputational damage.
TL;DR: Key Takeaways on Ransomware in Manufacturing
- One hundred eighty-four confirmed attacks in Q3 2025, the highest of any industry.
- Downtime = leverage. Production pressure makes manufacturers more likely to pay ransoms quickly.
- Operational technology (OT)/IT connections and vendors widen the attack surface.
- Ransomware-as-a-Service (RaaS) groups like Akira and Qilin are driving most of the activity.
- Containment beats prevention. Fast detection and recovery are now the strongest defenses.
Why Are Manufacturers Targeted So Often by Ransomware Groups?
Ransomware is widespread in the manufacturing industry because it operates in a lucrative, high-pressure environment. The wide range of potential attack surfaces makes manufacturing especially vulnerable.
In Q3 2025, the sector recorded 184 confirmed ransomware incidents, the highest of any industry, showing just how attractive these targets have become. Attackers recognize that manufacturers operate with minimal tolerance for downtime, and that even short disruptions can delay shipments and halt production lines.
The convergence of OT and IT has created new vulnerabilities. Once-isolated industrial systems now connect to enterprise networks for efficiency and data sharing, creating more entry points for attackers.
Compounding the risk are affiliate-based RaaS models, which make advanced attack tools widely accessible. Many affiliates gain entry through third-party vendors and remote-access pathways, allowing them to carry out attacks with little skill or effort.
What Techniques Do Ransomware Groups Use Against Manufacturing?
In Q3 2025, Akira (31 incidents), Qilin (24 incidents), and Play emerged as the most active threat groups targeting the manufacturing sector.
One of their primary tactics is double extortion, which involves exfiltrating sensitive data to pressure victims with the threat of public leaks. Many industrial ransomware attacks also exploit supply chain infiltration. This tactic involves exploiting trusted vendor connections or remote management tools to gain footholds in operational networks. These routes often bypass traditional defenses, allowing attackers to move laterally within systems.
Increased reliance on connectivity and automation, and the convergence of OT and IT within manufacturing, has also increased risk. OT misconfigurations and legacy equipment that lack modern security controls provide opportunities for exploitation. Once attackers are inside, they can disrupt industrial control systems. This disruption halts production, leading to costly downtime.
How Can Manufacturers Contain Attacks Quickly?
Focusing on prevention rather than rapid containment leaves manufacturers vulnerable to prolonged downtime and greater damage when ransomware inevitably breaches defenses. The ability to detect and contain attacks quickly is just as important as preventing them.
Some important metrics that directly influence the potential operational impact of an attack include:
- Time-to-contain, which measures how quickly an attack is stopped. A lower time-to-contain reduces damage and prevents lateral spread.
- Line restart time, which tracks how fast production resumes. It directly impacts revenue and operational continuity.
- Supplier notification lag, which ensures timely communication to partners. This can reduce supply chain disruptions and reputational damage.
Strengthening OT security through network segmentation is key to increasing ransomware prevention and reducing spread. Separating industrial control systems from enterprise systems limits lateral movement and prevents malware from spreading across your production lines. You should also have a clearly defined incident response plan that is clearly communicated across plant operations, IT, and security teams.
Using managed detection and response (MDR) with OT visibility provides another layer of defense by offering continuous monitoring and anomaly detection across IT and OT environments. This helps your teams identify and neutralize attacks quickly.
Strengthening Your Defense Against Ransomware in Manufacturing
Downtime is costly and can cause lasting reputational damage. Fast containment can reduce the impact of industrial ransomware attacks and help you get back up and running quickly.

FAQ: Ransomware in Manufacturing
What are the most common entry points for ransomware in manufacturing environments?
Right now, remote access tools, third-party vendor connections, and misconfigured OT security systems are some of the most common entry points in industrial ransomware attacks.
How does ransomware affect operational downtime in manufacturing?
Even short manufacturing cybersecurity breaches can halt production lines and delay shipments. This can create cascading supply chain disruptions and widespread operational downtime.
Is ransomware targeting manufacturers differently from attacks in other sectors?
Manufacturing attacks often exploit weak OT security and low tolerance for downtime. This increases the pressure on firms to pay ransoms.
What’s the role of third-party vendors in manufacturing ransomware attacks?
Third-party vendors provide access pathways that attackers can exploit to infiltrate systems.
