Honda’s keyless system has revealed a critical design flaw, allowing hackers to remotely open, close, and even start the engines of all Honda models.
The hacker attack, dubbed ‘Rolling-Pwn’, was discovered by Star-V Lab researchers Kevin2600 and Wesley Li, who learned that hackers could steal codes linked to key fobs and control the cars.
The researchers first made the report public in a blog post, identifying all models manufactured between 2012 and 2022 as being affected by the vulnerability. The flaw was spotted in a rolling codes program installed in all Honda vehicles. Authentication codes are exchanged between keyless entry systems and the key fobs, and in that window was where they had found the weakness.
Honda’s rolling codes mechanism should have prevented this from happening as it was implemented to send new codes each time someone unlocked their car. However, the cars have been noted to resynchronize every time they receive a lock or unlock command, allowing them to accept codes from previous sessions and hence giving hackers an in.
The researchers tested the hack out on 10 different models including the Honda Civic, Honda C-RV, and the Honda Accord. They filmed themselves in a series of videos which they put in their blog post to prove their findings. A representative from The Drive also tested it out himself and posted his findings on Twitter.
I was able to replicate the Rolling Pwn exploit using two different key captures from two different times.
Honda released a statement to Gizmodo via a spokesperson, saying that an attack like this requires complex knowledge and for the hacker to be in close range of the car. They assured drivers that the cars cannot be driven away and that this issue will be removed from future models.
