Zero-Days in the Fast Lane: Pwn2Own Automotive 2026 Exposes High-Stakes Car Hacking

The stakes have never been higher in the race to secure our cars. At Pwn2Own Automotive 2026, hackers and security researchers didn’t just pop the hood - they tore it off, revealing an engine of vulnerabilities powering the modern automotive ecosystem. With over half a million dollars in payouts and 37 zero-days uncovered, this year’s event signals a new era of automotive insecurity, where infotainment systems and EV chargers are as hackable as your email - and the consequences could be dire.

Fast Facts

• Total Payouts: $516,500 awarded for 37 zero-day exploits
• Targets Breached: Infotainment systems (Alpine, Kenwood, Sony), EV chargers (ChargePoint, Grizzl-E, Phoenix Contact), and automotive gateways
• Top Techniques: Command injections, buffer overflows, multi-bug chaining, protocol manipulation
• Leading Teams: Fuzzware.io, Summoning Team, Team MAMMOTH, Synacktiv
• Implications: Risks of remote control, grid attacks, and supply chain exposures in connected vehicles

Inside the Automotive Hackathon: How Cars Became Hackers’ New Playground

The second day of Pwn2Own Automotive 2026 was a spectacle of digital brinkmanship. Security teams went head-to-head, targeting a lineup of modern car tech - from dashboard infotainment units to the EV chargers fueling the electric revolution. By the close, 37 previously unknown vulnerabilities (“zero-days”) had been demonstrated in front of vendors and industry insiders.

The event’s format incentivizes not just finding bugs, but chaining them together for maximum impact. Teams like Fuzzware.io led the charge, orchestrating multi-stage attacks that blended authentication bypasses, privilege escalations, and memory exploits. Their attacks on Automotive Grade Linux and the ChargePoint Home Flex charger each netted tens of thousands of dollars and critical “Master of Pwn” points.

Command injection flaws were a recurring theme. In one standout hack, Team MAMMOTH exploited the Alpine iLX-F511 head unit, earning $10,000 for an attack that could grant an outsider control over the car’s infotainment system. Meanwhile, collisions - multiple teams hitting the same bug - highlighted how widespread and poorly defended some vulnerabilities are, particularly in Alpine and Kenwood firmware.

EV chargers emerged as a high-value target. Attacks on Grizzl-E, ChargePoint, and Phoenix Contact revealed that manipulating charging protocols and exploiting buffer overflows could allow not just data theft but physical tampering or even disruption of the power grid. The potential for chained vulnerabilities to escalate privileges and reach root access amplifies the threat.

The Zero Day Initiative (ZDI) ensures responsible disclosure, but the sheer volume and diversity of bugs show that automakers and suppliers are lagging behind the hacker curve. The event’s $516,500 prize pool is not just a reward - it’s a warning. As vehicles become rolling computers, the risks are multiplying, and hackers are proving that even the most advanced systems can be breached.

Conclusion: No More Coasting on Security

Pwn2Own Automotive 2026 didn’t just shatter payout records - it shattered illusions about the safety of our cars and charging networks. As researchers race for “Master of Pwn” glory, vendors must race to patch the holes before real-world attacks hit the road. The message is clear: input validation, robust authentication, and relentless code review aren’t optional - they’re the only way to keep our vehicles safe in a world where the next zero-day may already be in the wild.

WIKICROOK

• Zero: A zero-day vulnerability is a hidden security flaw unknown to the software maker, with no fix available, making it highly valuable and dangerous to attackers.
• Command Injection: Command Injection is a vulnerability where attackers trick systems into running unauthorized commands by inserting malicious input into user fields or interfaces.
• Buffer Overflow: A buffer overflow is a software flaw where too much data is written to memory, potentially letting hackers exploit the system by running malicious code.
• Privilege Escalation: Privilege escalation occurs when an attacker gains higher-level access, moving from a regular user account to administrator privileges on a system or network.
• Responsible Disclosure: Responsible Disclosure is when security flaws are privately reported to vendors, allowing them to fix issues before the information is made public.
