Indiana Cyber Threat Landscape: Which Industries Are Most at Risk?

Indiana punches above its weight in industries that cybercriminals and nation-state actors actively target. The state leads the nation in manufacturing output as a share of GDP, hosts one of the largest life sciences corridors in the world, and is home to the Indianapolis Motor Speedway — the epicenter of a motorsports technology ecosystem that generates proprietary engineering data worth protecting. These industries do not face generic, one-size-fits-all cyber threats. Each has a distinct risk profile shaped by the type of data it generates, the systems it depends on, and the adversaries most likely to target it.

This analysis examines Indiana's cyber threat landscape through the lens of its key industries, drawing on real Indiana breach incidents and current threat intelligence to help organizations understand where they stand and what practical steps reduce exposure. Indiana's regulatory environment, detailed in our Indiana compliance guide, adds urgency to these security considerations as the state strengthens its data protection framework.

Indiana Economic Profile and Cyber Risk Exposure

Indiana's economy generated approximately $451 billion in GDP in 2024, with manufacturing contributing a larger share than any other state — roughly 27% of the state's total output. This economic composition creates a cybersecurity risk profile unlike states dominated by financial services or technology.

• Manufacturing: Over 8,700 manufacturing establishments employ approximately 530,000 Hoosiers. Key subsectors include automotive (Subaru, Honda, Toyota, General Motors), steel (U.S. Steel Gary Works, ArcelorMittal Burns Harbor), medical devices (Warsaw orthopedic corridor), aerospace components, and RV manufacturing (Elkhart County produces roughly 80% of U.S. recreational vehicles).

• Life sciences: Indianapolis is home to Eli Lilly and Company, Roche Diagnostics, Corteva Agriscience, and hundreds of biotech, pharmaceutical, and contract research organizations. Indiana's life sciences sector employs over 56,000 workers and generates billions in annual revenue.

• Healthcare: Major systems including IU Health (Indiana's largest employer), Community Health Network, Franciscan Health, and Parkview Health operate hundreds of facilities statewide. Indiana has approximately 170 hospitals and thousands of specialty practices.

• Motorsports technology: The Indianapolis Motor Speedway and the broader Indiana motorsports corridor support a cluster of engineering firms, aerodynamics consultancies, and advanced materials companies that generate highly proprietary performance data and design specifications.

• Defense: Naval Surface Warfare Center Crane Division (NSWC Crane) in Martin County is a major DoD installation, and hundreds of Indiana manufacturers serve as defense subcontractors handling controlled unclassified information.

Top Cyber Threats Facing Indiana Businesses in 2025

Ransomware Targeting Healthcare and Manufacturing

Ransomware remains the most destructive threat to Indiana organizations. The Eskenazi Health attack in 2021, which forced ambulance diversions across Indianapolis, demonstrated the life-safety implications of ransomware in clinical settings. Manufacturing is equally vulnerable — ransomware that halts a production line at an automotive supplier can cascade through just-in-time supply chains, causing losses that far exceed the ransom demand. Groups including LockBit, BlackCat/ALPHV successors, Cl0p, and Play ransomware have all targeted organizations in the Midwest manufacturing belt that includes Indiana.

Intellectual Property Theft in Life Sciences

Indiana's concentration of pharmaceutical and biotech companies makes it a high-priority target for nation-state espionage, particularly from groups linked to China. The theft of drug formulations, clinical trial data, and manufacturing processes can shortcut years of R&D investment worth billions of dollars. Advanced persistent threat groups including APT41, APT10, and others attributed to Chinese state-sponsored operations have historically targeted pharmaceutical companies. Eli Lilly's presence in Indianapolis — one of the largest pharmaceutical companies in the world — along with hundreds of smaller firms, creates a dense target environment for IP theft campaigns that often use spear-phishing, supply chain compromise, or exploitation of research collaboration platforms.

Operational Technology Attacks on Manufacturing

Indiana's manufacturing sector is undergoing rapid digital transformation, connecting previously isolated operational technology (OT) systems — including programmable logic controllers (PLCs), SCADA systems, industrial robots, and CNC machines — to corporate IT networks for monitoring, analytics, and remote management. This IT/OT convergence creates attack paths that did not exist when factory floors were air-gapped. A phishing email that compromises an engineer's workstation can now potentially pivot to systems controlling physical production processes. The consequences range from production shutdowns and quality defects to physical safety hazards. Steel mills in northwest Indiana, automotive plants across the state, and RV manufacturers in Elkhart all face this converging threat.

Supply Chain Compromise

Indiana's role as a manufacturing and logistics hub means that many Hoosier businesses are embedded in complex supply chains where a compromise at any tier can cascade. The 2023 MOVEit breach that affected the Indiana Public Retirement System arrived through a third-party vendor, not through a direct attack on state systems. Indiana manufacturers that serve as Tier 1 or Tier 2 automotive suppliers are attractive targets because compromising a single supplier can provide access to multiple OEMs. The logistics and warehousing operations concentrated around Indianapolis — which sits within a day's drive of 80% of the U.S. population — add another dimension of supply chain cyber risk.

Business Email Compromise

BEC attacks targeting Indiana businesses generate some of the highest dollar losses of any cybercrime category. Real estate transactions, manufacturer payment processes, and payroll systems are commonly targeted. The FBI's Indianapolis field office has reported consistent growth in BEC complaints from Indiana, with losses often exceeding $100,000 per incident. The attacks increasingly incorporate AI-generated voice deepfakes and compromised email threads that make fraudulent payment requests nearly indistinguishable from legitimate ones.

Industry Spotlight: Indiana Manufacturing Cybersecurity

Manufacturing deserves focused attention because Indiana leads the nation in this sector and because the cybersecurity challenges are uniquely complex.

The IT/OT Convergence Challenge

Historically, factory-floor systems operated in isolation from corporate networks. A PLC controlling a stamping press or a SCADA system managing steel rolling processes had no connection to email servers or the internet. Indiana manufacturers pursuing Industry 4.0 initiatives — predictive maintenance, digital twins, real-time quality monitoring — are bridging this gap, often without adequate security architecture. The result is that a ransomware infection that enters through a phishing email can propagate to systems controlling physical processes. Addressing this requires manufacturing cybersecurity expertise that spans both IT and OT domains.

Automotive Supply Chain Pressure

Indiana's automotive manufacturing cluster — Subaru of Indiana Automotive in Lafayette, Honda Manufacturing of Indiana in Greensburg, Toyota Motor Manufacturing Indiana in Princeton, General Motors Fort Wayne Assembly — depends on hundreds of local suppliers operating on just-in-time schedules. A cyberattack that shuts down a single Tier 2 supplier producing brake components or wiring harnesses can halt production at an assembly plant within hours. OEMs increasingly require cybersecurity attestations from suppliers, and the Trusted Information Security Assessment Exchange (TISAX) standard is gaining traction alongside NIST frameworks in automotive supply chains.

The Orthopedic Capital of the World

Warsaw, Indiana, is known globally as the orthopedic capital of the world, home to Zimmer Biomet, DePuy Synthes (a Johnson & Johnson company), Biomet, and dozens of smaller device manufacturers and suppliers. These companies hold intellectual property related to implant designs, surgical instruments, manufacturing processes, and clinical outcome data. The combination of high-value IP and FDA-regulated manufacturing processes creates a cybersecurity challenge that spans both data protection and operational continuity. A ransomware attack that compromises a medical device manufacturer's quality management system can halt production and trigger regulatory implications beyond the immediate security incident.

Motorsports Technology: An Emerging Cyber Target

The Indianapolis Motor Speedway and the broader Indiana motorsports ecosystem represent a unique and underappreciated cyber risk domain. IndyCar teams, NASCAR operations based in the region, and the engineering firms that support them generate enormous quantities of proprietary data — aerodynamic simulations, telemetry data, engine performance parameters, tire degradation models, and race strategy algorithms. This data represents millions of dollars in competitive advantage.

Motorsports technology firms increasingly rely on cloud-based simulation platforms, real-time data transmission from track to engineering centers, and collaborative design tools that create network-exposed attack surfaces. While no major publicly disclosed breach has targeted Indiana's motorsports technology cluster specifically, the sector's reliance on proprietary engineering data and compressed competitive timelines makes it an attractive target for both corporate espionage and opportunistic ransomware operators who understand the time pressure of race schedules.

The Cyber Insurance Landscape in Indiana

Cyber insurance has become essential risk management for Indiana businesses, but underwriting standards have tightened significantly. Insurers require evidence of specific security controls before issuing or renewing policies.

• Multi-factor authentication on all remote access, email, and privileged accounts

• Endpoint detection and response (EDR) deployed across all endpoints

• Regular patching with evidence of vulnerability management

• Offline or immutable backups tested for restoration

• Documented and tested incident response plan

• Employee security awareness training with measured outcomes

• Privileged access management for administrative accounts

Indiana manufacturers and healthcare organizations frequently encounter premium increases or coverage exclusions related to legacy systems, OT environments, and connected medical devices that insurers view as elevated risk. Organizations that cannot demonstrate adequate controls may find coverage unavailable at any price.

How Indiana Businesses Can Reduce Cyber Risk

Reducing cyber risk in Indiana requires prioritizing actions based on your industry, threat profile, and current security maturity. The following recommendations apply broadly:

• Secure the basics first — multi-factor authentication, endpoint detection, regular patching, and tested offline backups address the most common attack vectors responsible for Indiana incidents

• Segment IT and OT networks — if you operate in manufacturing, ensure that factory-floor systems are isolated from corporate IT networks with monitored chokepoints between zones. This is the single most important control for Indiana manufacturers pursuing digital transformation

• Protect intellectual property — life sciences and motorsports technology firms should implement data loss prevention controls, monitor for unauthorized data exfiltration, and apply least-privilege access to R&D environments

• Know your regulatory obligations — understand which Indiana laws, federal regulations, and customer requirements apply to your organization. The Indiana compliance guide provides a detailed breakdown

• Address third-party risk — audit vendor security practices, require contractual security obligations, and monitor third-party access to your systems. Indiana's breach history shows that vendor compromise is a recurring entry point

• Plan for ransomware — assume you will be targeted and build resilience through segmentation, offline backups, and practiced incident response that accounts for both IT and OT recovery

Organizations that lack dedicated security teams should evaluate managed IT services and managed security services partnerships that provide continuous monitoring, vulnerability management, and incident response. For manufacturers with OT environments, manufacturing cybersecurity providers with industrial control system expertise can address the specialized requirements that general IT firms cannot.

Frequently Asked Questions

What makes Indiana a significant cyber target compared to other Midwestern states?

Indiana's disproportionate concentration of manufacturing — the highest share of GDP from manufacturing of any U.S. state — combined with its life sciences corridor, major defense installations at NSWC Crane, and role as a logistics hub creates an unusually dense collection of high-value targets. The state's manufacturing output alone exceeds that of many entire countries, generating intellectual property and operational data that attract both financially motivated criminals and nation-state espionage groups.

Are Indiana manufacturers required to meet specific cybersecurity standards?

There is no single Indiana state mandate requiring all manufacturers to follow a specific cybersecurity framework. However, manufacturers serving as defense contractors must achieve CMMC compliance for handling controlled unclassified information. Automotive suppliers increasingly face TISAX requirements from OEMs. Many Indiana manufacturers also adopt NIST CSF or CIS Controls voluntarily or in response to customer requirements and cyber insurance underwriting standards. The practical effect is that most Indiana manufacturers face de facto cybersecurity requirements through their supply chain relationships even absent a direct state mandate.

How are ransomware groups targeting Indiana healthcare providers?

Ransomware groups target Indiana healthcare providers primarily through phishing campaigns aimed at clinical and administrative staff email accounts, exploitation of internet-facing remote access systems (VPNs and remote desktop), and supply chain compromise of healthcare IT vendors. The Vice Society attack on Eskenazi Health entered through common attack vectors that MFA and email security would have mitigated. Healthcare organizations face compounded pressure because operational downtime directly threatens patient safety, which attackers exploit to increase payment likelihood.

Is intellectual property theft a real threat to Indiana life sciences companies?

Yes. The FBI and CISA have issued multiple advisories identifying pharmaceutical and biotech companies as priority targets for nation-state espionage, particularly by Chinese-affiliated groups. Indiana's concentration of pharmaceutical research, led by Eli Lilly but extending across hundreds of firms, makes Indianapolis a focal point. The value of stolen drug development data — which can represent billions in R&D investment — makes life sciences IP theft one of the highest-impact cyber threats in the state, even though individual incidents are rarely disclosed publicly due to national security and competitive sensitivity.

What role does NSWC Crane play in Indiana's cybersecurity landscape?

Naval Surface Warfare Center Crane Division is a major Department of Defense installation in Martin County that supports weapons systems, electronic warfare, and strategic missions. Its presence in Indiana means hundreds of local companies serve as defense subcontractors and must meet CMMC requirements for handling controlled unclassified information. NSWC Crane also operates the Midwest Microelectronics Consortium and has invested in supply chain security research, making it an anchor for defense cybersecurity capability development in the region. The facility's requirements cascade through Indiana's manufacturing supply chain, raising the baseline security expectations for companies that might otherwise not prioritize cybersecurity.
