Summary:

This is a proof of concept for CVE-2022-27254, wherein the remote keyless system on various Honda vehicles send the same, unencrypted RF signal for each door-open, door-close, boot-open and remote start(if applicable). This allows for an attacker to eavesdrop on the request and conduct a replay attack.

POC videos:

Remote.start.sequence.mp4
Door.unlock.sequence.mp4
Door.lock.sequence.mp4

Vehicles Affected:

• 2016-2020 Honda Civic(LX, EX, EX-L, Touring, Si, Type R)

Important Notes:

 •Key fob FCC ID: KR5V2X

 •Key fob frequency: 433.215MHz

 •Key fob modulation: FSK

Tools used:

       •FCCID.io
       •HackRF One
       •Gqrx
       •GNURadio

Prevention:

  • Manufacturers:

    1. Manufacturers must implement Rolling Codes, otherwise known as hopping code. It is a security technology commonly used to provide a fresh code for each authentication of a remote keyless entry (RKE) or passive keyless entry (PKE) system.

  • Consumers:

    1. Utilize a Faraday Pouch for the key fob.
    2. Use the PKE as opposed to the RKE, this would make it significantly harder for an attacker to clone/read the signal due to the proximity they would need to be at to do so.

⚠️ The precautions mentioned above ARE NOT foolproof ⚠️

If you believe that you are a victim of this attack, the only current mitigation is to reset your key fob at the dealership.
