Executive Summary
In January 2026, security researchers at the Pwn2Own Automotive competition in Tokyo successfully exploited 37 zero-day vulnerabilities across flagship automotive technologies, including Tesla's infotainment system, multiple EV chargers, and in-vehicle digital receivers. The Synacktiv team achieved root access on the Tesla Infotainment System through chained vulnerabilities involving an information leak and out-of-bounds write flaw via USB. Other researchers compromised systems from Sony, Alpitronic, Autel, Kenwood, and Phoenix Contact. The event demonstrates the breadth of exploitable attack surfaces even in patched, production automotive hardware and highlights coordinated vulnerability disclosure processes wherein vendors have 90 days to issue fixes.
This incident underscores how automotive technology—including electric vehicles and charging infrastructure—remains a top target for advanced security researchers, with new zero-day vulnerabilities continually emerging. As vehicle software stacks grow in complexity and interconnectivity, the imperative for proactive, industry-wide security controls and coordinated patch processes is increasingly urgent.
Why This Matters Now
Automotive systems are rapidly digitizing, making them lucrative and vulnerable targets for both security researchers and real-world threat actors. High-profile public demonstrations of root access and multi-vendor vulnerabilities emphasize the need for continuous security investment and quick incident response across the entire automotive ecosystem.
Attack Path Analysis
Attackers gained initial access to the Tesla Infotainment System by exploiting previously unknown zero-day vulnerabilities via USB-based attack vectors. After gaining a foothold, they escalated privileges to obtain root permissions on targeted devices. From this privileged position, they could have potentially moved laterally within interconnected systems (e.g., between components of the IVI, chargers, or backend APIs). The attackers established command and control by maintaining remote access or implanting persistent code. Data or sensitive info could have been exfiltrated from compromised systems, exposing proprietary data or customer credentials. The impact included demonstration of system takeovers and public disclosure of vulnerabilities, with potential for real-world system disruptions had this been a malicious adversary.

Frequently Asked Questions
Cloud Native Security Fabric Mitigations and ControlsCNSF
Applying Zero Trust segmentation, east-west traffic controls, egress filtering, and real-time anomaly detection would have significantly limited attacker progression after initial compromise. CNSF-aligned controls create containment zones, enforce least privilege, block lateral pivoting, and restrict outbound data flow, reducing the overall attack surface and potential for compromise propagation.
