2017 Toyota Wigo S Rollback Attack using Portapack H2 + HackRF One

Mar 22, 2023

A Rollback / Rolling-Pwn attack is not really a new replay attack against remote keyless entry systems and keyfobs but a new term for time-agnostic replay attacks despite having rolling codes. Some people have already disclosed this in the past, but researchers Levente Csikor and others published a better PoC about it and its prevalence in newer vehicles. A rolling code system in keyless entry systems is one of the solutions to prevent replay attacks. However, some vehicle receivers will accept a sliding window of code in order to avoid accidental key pressed by design.
