Cybersecurity for:
Automotive

Why is the automotive sector a target for cyberattacks?

The automotive industry has undergone a fundamental digital transformation. A modern vehicle contains over 100 million lines of code, dozens of ECU controllers, and connects to manufacturer cloud systems through V2X (Vehicle-to-Everything) interfaces. Simultaneously, car factories integrate IT networks with production lines powered by PLC controllers and industrial robots. This convergence creates a massive attack surface.

Attackers target automotive for three reasons: the value of intellectual property (ADAS designs, autonomous driving algorithms), the ability to extort ransoms by halting production, and the potential to manipulate vehicle physical safety systems.

Sector-specific challenges

Supply chain complexity

OEMs collaborate with hundreds of Tier 1, Tier 2, and Tier 3 suppliers. Each represents a potential entry point into the manufacturer’s network. Compromising a single electronic component supplier can enable malicious firmware injection into thousands of vehicles. The TISAX standard was created specifically to address this threat — requiring suppliers to certify their information security practices.

Connected vehicle security

CAN bus protocols, automotive Ethernet, and OBD-II interfaces were not designed with cybersecurity in mind. Remote vehicle attacks — from infotainment system takeover to brake manipulation — are well-documented in security research. ISO 21434 defines security requirements across every stage of the vehicle lifecycle.

IT/OT convergence in factories

Production lines built on Kuka, Fanuc, and ABB robots connect to MES, ERP, and cloud systems. Ransomware spreading from the office network to the shop floor can halt a factory for days — as demonstrated in attacks on Toyota (2022) and Continental (2022).

How nFlo helps the automotive industry

• Penetration testing — testing connected system security, V2X interfaces, and manufacturer infrastructure
• Security audits — TISAX and ISO 21434 compliance assessment, supply chain gap identification
• OT/ICS security audit — production line security, PLC controllers, and SCADA systems in factories

Key first steps

1. TISAX audit — if you are an OEM supplier, TISAX certification is a contractual requirement
2. IT/OT segmentation — separate the office network from production control systems
3. Asset inventory — map all controllers, sensors, and connections in the factory
4. Incident response plan — scenarios covering both IT disruptions and production shutdowns
