Manufacturing Emerges as Primary Cyberattack Target
The manufacturing sector faced the highest number of cyber attacks in 2023, according to reports from Statista, with industry analysts suggesting the complexity of global operations makes the industry uniquely exposed to digital threats. Sources indicate that manufacturers face dual challenges as both recipients and distributors of supply chain risk, creating multiple attack vectors for malicious actors.
Serious Vulnerabilities Outpace Other Industries
Based on 16,000 penetration tests conducted over 10 years, manufacturing consistently ranks near the top of all industries for serious vulnerabilities uncovered, the report states. Analysis reveals an average of 18 percent of manufacturing system vulnerabilities are rated serious—far ahead of financial services and information services, which average 11 percent. According to cybersecurity experts, this vulnerability gap presents significant concerns given that manufacturers are targeted by both nation-state actors and organized crime groups.
Expanded Supply Chain Creates Multiple Attack Points
The sheer scale of modern supply chains represents a critical weakness, analysts suggest. In aerospace manufacturing, for example, a single product may rely on tens of thousands of suppliers, each representing potential compromise points. Security researchers note that criminals often target seemingly low-impact components, where security oversight might be less rigorous. Hardware subversion through tampered microchips introduced via gray markets presents additional risks, with reports indicating even organizations like NASA have encountered counterfeit electronic parts in their systems.
Proactive Security Measures Recommended
Industry experts recommend several key strategies to mitigate these growing threats. According to cybersecurity professionals, manufacturers should enforce strict supplier security requirements, including mandatory annual offensive security testing and comprehensive security questionnaires. The State of Pentesting Report 2025 emphasizes that transparency throughout the supply chain, including sharing penetration test results, is crucial for comprehensive protection.
Red Team Testing and Physical Security Assessments
Manufacturers are increasingly implementing ‘Red Team’ exercises where ethical hackers simulate supply chain compromises, including vendor impersonation and rogue firmware insertion. Physical security testing, involving component teardowns and hacking attempts, has also proven effective in identifying tampered hardware. Security specialists suggest that even sampling two devices per batch of 1,000 can significantly improve overall device integrity when combined with cryptographically signed firmware from original equipment manufacturers.
Legacy Systems and Employee Education Challenges
The prevalence of legacy equipment not originally designed for internet connectivity presents additional security hurdles. According to cyber security guidance for the manufacturing industry, employee education is essential since well-intentioned workers may connect inherently vulnerable equipment to networks. Security professionals note that while manufacturers would prefer newer, more secure technology, tight margins often necessitate continued use of older systems that cannot easily be replaced.
Industry-Wide Response to Growing Threats
As criminal tools become more accessible and AI enhances attack capabilities, the barriers to cyberattack continue to lower. Meanwhile, industry developments such as the BlackRock-NVIDIA consortium’s acquisition of Aligne and Apple’s launch of the M5 chip highlight the ongoing technological evolution within manufacturing sectors. Additionally, geopolitical factors, including the UK government’s released evidence regarding China, underscore the complex international landscape in which manufacturers operate.
Comprehensive Approach Required
While penetration testing remains a valuable tool for identifying vulnerabilities before criminals can exploit them, security experts emphasize it represents just one component of a programmatic security approach. Given the manufacturing sector’s complexity, analysts suggest no company can guarantee complete safety, but implementing layered security measures can significantly improve resilience and potentially deter opportunistic attackers seeking easier targets.
