CYMOTIVE Technologies to present a new vulnerability in automotive cyber at ESCAR USA

June 14, 2022

New vulnerability discovery in common CAN-FD vehicle communication protocol    

Ypsilanti, Michigan, June 14, 2022, CYMOTIVE Technologies, the leading provider of smart mobility cyber solutions, today announced its participation in the international automotive security event ESCAR USA taking place on June 15 -16, 2022. On the first day at 9:45 am EST, CYMOTIVE’s Principal Cyber Security Researcher, Matan Ziv, will present research entitled “CAN-in-CAN Attack for Bypassing Security, revealing a new potential attack on the CAN-FD (Controller Area Network Flexible Data-Rate) vehicle communication protocol. Matan has named the vulnerability “CANCAN”, referring to an ancient proverb on looking inside a person for hidden truth.

Vulnerabilities in these common communication protocols carry significant ramifications for the cybersecurity readiness of many vehicle models. The CANCAN vulnerability allows one CAN-FD message to hide inside another. As the encapsulating message hiding the other will appear as valid, the CANCAN vulnerability may be used for circumventing various security measures.

“We applaud Matan Ziv and the CYMOTIVE cybersecurity research team for this milestone in securing the automotive eco-system,” said Tsafrir Kats, CEO and Co-founder of CYMOTIVE Technologies. “The CANCAN vulnerability may affect any vehicle component implementing the CAN-FD protocol and those protocols currently in development, such as CAN-XL, unless specifically addressed. We encourage all car manufacturers and their suppliers to take note and consider mitigation of this vulnerability.”

CYMOTIVE is also a sponsor of the ESCAR USA event taking place in the Ann Arbor Marriott Ypsilanti at Eagle Crest, in Ypsilanti, Michigan. If interested in meeting the CYMOTIVE cyber experts attending ESCAR, please contact us here.
