Manufacturing Industry Tops Cyber Attack Targets
The manufacturing sector has become the most targeted industry for cybercriminals, with attacks reaching unprecedented levels according to recent data. Sources indicate that manufacturing faced the highest number of cyber attacks in 2023, with the complexity of global supply chains creating unique exposure to digital threats.

Dual Threat Dynamics in Manufacturing Security
Analysts suggest there are two core dynamics creating security challenges for manufacturers. Firstly, manufacturers receive supply chain risk through sourcing components from hundreds or even tens of thousands of suppliers. Secondly, they become vendors themselves, potentially supplying compromised products unknowingly. The supply chain complexity means vulnerabilities can be introduced at multiple points in the production process.
Serious Vulnerability Rates Exceed Other Industries
According to reports spanning 16,000 penetration tests conducted over 10 years, manufacturing consistently ranks near the top of all industries for serious vulnerabilities uncovered. The sector averages 18 percent serious vulnerabilities, far ahead of financial services and information services which average 11 percent. Testing data reveals that penetration testing, where skilled professionals assume the role of hackers, helps uncover threats before criminals can exploit them.
Nation States and Organized Crime Target Manufacturers
The report states that manufacturers face threats from both nation state actors and organized crime groups. Nation state actors may plan compromises years in advance, embedding persistent access across critical supply chains in preparation for future conflicts. Meanwhile, organized crime groups typically pursue more opportunistic attacks for financial gain, according to security analysts.
Supplier Volume Amplifies Security Risks
Sources indicate that the sheer number of suppliers represents a significant weakness. In aerospace manufacturing, for example, a single product may rely on tens of thousands of suppliers, each representing potential compromise points. Criminal hackers could target vulnerabilities in seemingly low-impact components, such as rivet suppliers, with effects that differ from but remain as dangerous as compromises in critical technology vendors.
Hardware Subversion Through Gray Markets
Hardware subversion presents another serious risk, with tampered or fraudulent microchips introduced through gray markets potentially containing backdoors or defects. According to industry reports, cost pressures and procurement shortages drive companies toward these risky sources. Even organizations with high security standards have been compromised, as NASA safety documentation has previously acknowledged counterfeit electronic parts challenges.
Comprehensive Security Measures Required
Security experts recommend multiple approaches to reduce manufacturing cyber risk:
- Supplier Security Requirements: Mandating annual offensive security testing and security questionnaires for vendors
- Transparent Testing: Ensuring penetration test reports are shared throughout the supply chain
- Red Team Testing: Conducting simulated supply chain compromises including vendor impersonation and rogue firmware insertion
- Vendor Sampling: Physical security testing of component batches, including teardown and hacking attempts
Legacy Systems and Employee Education Challenges
The manufacturing environment often contains legacy devices not originally designed for internet connectivity that have been connected despite inherent vulnerabilities. According to cyber security guidance for manufacturing, employee education is essential since well-meaning staff may connect vulnerable equipment. Some facilities still operate devices supported by Windows 98, which security professionals recommend keeping isolated from public internet access.

Proactive Security in an Evolving Threat Landscape
While manufacturers face significant challenges, analysts suggest that taking proactive measures can substantially improve security posture. As criminal tools become more accessible and effective through AI advancements, companies that implement comprehensive security programs including regular penetration testing, supplier management, and employee education may deter opportunistic attackers who typically seek easier targets. Industry experts emphasize that while no organization can guarantee complete safety, these measures significantly reduce risk in an increasingly connected manufacturing ecosystem.
