Relay Attack Vulnerabilities Force Authentication Redesign
Keyless entry systems have become vulnerable to relay attacks that amplify key fob signals to open vehicles without the owner present, and that vulnerability has forced automakers to redesign authentication protocols that were considered secure just a few years ago. Continental AG and Robert Bosch have both expanded ultra-wideband and encrypted authentication development specifically to close this vulnerability rather than relying on incremental patches to existing systems. This redesign effort is spreading across the broader supplier base as relay attack incidents continue rising in major markets worldwide, reflecting how quickly relay attack exposure is reshaping supplier investment priorities industry-wide.
Market Impact: Vehicle theft rates rose 4-5% annually
