Saint Rolling-PWN, Who Opened Cars With Yesterday's Code
Patron of wireless keys, rolling codes, and those who think a remote is enough to lock up.
Life
In 2022 researchers Kevin2600 and Wesley Li showed Rolling-PWN: on many Honda cars the rolling codes of the key fobs, meant never to repeat, could be resynchronised by sending several in sequence. Having captured a few legitimate codes, the attacker could reuse them to open the doors, defeating the very replay protection the whole scheme was supposed to guarantee.
Prayer
O Saint Rolling-PWN, who opens doors with yesterday's code, teach our remotes never to accept the same greeting twice. Amen.
How to celebrate
Celebrated by updating the car's firmware when the maker offers it, and guarding the key as people once guarded metal ones.
Yesterday's code, today's open door.
