Based on the 2026 Arctic Wolf Threat and Predictions Report and IBM’s X-Force 2025 Threat Intelligence Index, manufacturing stands as the top-targeted industry for cyber attacks with the “highest victim count.”
When analyzing the top cyber threats facing this sector, the vast majority are defined by ransomware and related data extortion. Driven by a low tolerance for operational downtime, interconnected supply chains, and valuable intellectual property, manufacturers have become the primary target for ransomware gangs looking for fast, high-dollar payouts.
Why Ransomware Targets Manufacturing
Threat actors heavily favor ransomware against manufacturers due to specific industry vulnerabilities:
- High Cost of Downtime: Factory downtime can cost millions of dollars per day. Ransomware groups exploit this urgency to force rapid ransom payments.
- Connected IT/OT Vulnerabilities: Modern production lines rely on interconnected IoT devices and legacy Operational Technology (OT) software, providing ample entry points for ransomware payloads.
- Supply Chain Leverage: Disrupting a major manufacturer ripples across thousands of global suppliers, magnifying the pressure to pay and restore operations.
- Double Extortion: Attackers steal sensitive industrial processes, blueprints, and employee/customer data before encrypting networks, threatening to leak the information if the ransom isn’t met.
Analysis of Top Industry Attacks: A Ransomware Majority
The threat landscape is overwhelmingly defined by ransomware campaigns. Out of the 10 major manufacturing cyber attacks detailed in the report, the clear majority are confirmed or highly suspected ransomware incidents:
| Organization | Threat Type | Cost / Impact | Key Ransomware / Extortion Details |
| Jaguar Land Rover (2025) | Ransomware | £196M direct / £1.9B economy | Hit by the Scattered Lapsus Hunters collective; halted production for 5 weeks. |
| Applied Materials (2023) | Ransomware | $250 Million USD | A supply-chain ransomware attack stemming from MKS Instruments that halted shipments. |
| Clorox (2023) | Suspected Ransomware | $356 Million USD | Acted like ransomware; took automated ordering systems offline and dropped sales by 20%. |
| Simpson Manufacturing (2023) | Suspected Ransomware | Undisclosed | Incident response mirrored ransomware protocols; systems were forced offline for months. |
| Toyota (2022/2023) | Ransomware & Breach | $8 Million USD ransom | Medusa ransomware targeted German financial services; separate attacks halted 14 factories. |
| Bridgestone Americas (2022) | Ransomware | Undisclosed | Hit by the LockBit gang; exfiltrated data and knocked North/Latin American plants offline. |
| JBS (2021) | Ransomware | $11 Million USD | Conducted by Russia’s REvil group; paid the multi-million dollar ransom to secure files. |
| Norsk Hydro (2019) | Ransomware | $70 Million USD | Infiltrated via LockerGoga ransomware; the company refused to pay and ran operations manually. |
| Mondelez International (2017) | Encrypting Malware | $100 Million USD | Leveraged NotPetya malware to permanently wipe 1,700 servers and 24,000 laptops. |
| Brunswick Corporation (2023) | Data Breach | $85 Million USD | Disrupted operations for 9 days and compromised massive amounts of customer/employee PII. |
Key Statistic: The raw count of victimized manufacturers nearly doubled from 2024 to 2025. For incidents handled by Arctic Wolf Incident Response, the median cost of a manufacturing ransomware attack has reached $600,000 USD.
Since the Arctic Wolf report was released, several other manufacturers have been targeted with significant ransomware attacks, including the following:
- West Pharmaceutical Services, Inc. – A ransomware attack disrupted manufacturing, shipping, and receiving operations across global facilities when attackers breached a network on May 4, 2026. According to a filing with the U.S. Securities and Exchange Commission, hackers stole data and encrypted systems, which required WPS to proactively “shut down portions of its infrastructure to contain the incident.”
- Foxconn – The company confirmed that a cyberattack initiated by the Nitrogen ransomware group impacted several North American factories. The group claimed it stole 8 TB of data and more than 11 million files from the company, including hardware schematics and network topologies for major clients like Intel and Google.
- Indiana Mills and Manufacturing – IMMI, a major U.S. manufacturer specializing in advanced safety and crash-protection systems (like seatbelts and commercial vehicle safety restraints), was hit by the Termite ransomware group. The attackers issued a public 24-hour ultimatum threatening to leak highly sensitive proprietary data and corporate files if the company did not immediately initiate ransom negotiations.
Defensive Strategies Against Ransomware
To defend against pervasive ransomware threats, manufacturing organizations must pivot toward comprehensive cybersecurity operations:
- 24/7 Monitoring: Establishing total visibility across IT, OT, and IoT environments to catch ransomware payloads before they can execute.
- Identity Security & Zero Trust: Utilizing Multi-Factor Authentication (MFA) and Identity Threat Detection and Response (ITDR) to block credential-stuffed entry points.
- Security Awareness Training: Educating workforce populations to spot phishing emails—the primary delivery vehicle for Trojan horses and ransomware strains.
- Strategic Security Partnerships: Collaborating with MSP partners to ensure continuous, industry-specific threat hunting and attack surface hardening.
