Forscher hacken E-Auto-Systeme

Trend Micro's Zero Day Initiative sponsored its third annual Pwn2Own Automotive competition in Tokyo this week, receiving 73 entries, the most ever for a Pwn2Own event.

"Under Pwn2Own rules, all disclosed vulnerabilities are reported to affected vendors through ZDI," reports Help Net Security, "with public disclosure delayed to allow time for patches." Infotainment platforms from Tesla, Sony, and Alpine were among the systems compromised during demonstrations. Researchers achieved code execution using techniques that included buffer overflows, information leaks, and logic flaws. One Tesla infotainment unit was compromised through a USB-based attack, resulting in root-level access. Electric vehicle charging infrastructure also received significant attention. Teams successfully demonstrated exploits against chargers from Autel, Phoenix Contact, ChargePoint, Grizzl-E, Alpitronic, and EMPORIA. Several attacks involved chaining multiple vulnerabilities to manipulate charging behavior or execute code on the device. These demonstrations highlighted how charging stations operate as network-connected systems with direct interaction with vehicles.
There's video recaps on the ZDI YouTube channel — apparently the Fuzzware.io researchers "were able to take over a Phoenix Contact EV charger over bluetooth."

Three researchers also exploited the Alpitronic's HYC50 fast-charging with a classic TOCTOU bug, according to the event's site, "and installed a playable version of Doom to boot." They earned $20,000 — part of $1,047,000 USD was awarded during the three-day event.

More coverage from SecurityWeek: The winner of the event, the Fuzzware.io team, earned a total of $215,500 for its exploits. The team received the highest individual reward: $60,000 for an Alpitronic HYC50 EV charger exploit delivered through the charging gun. ZDI described it as "the first public exploit of a supercharger".
