Welcome to my abode, spies!

WIRED · Hackers Found a Way to Open Any of 3 Million Hotel Keycard Locks in SecondsBy Andy Greenberg

@ppatel

Years ago I worked at a hotel that used Saflok, But at the time it was not RFID. Cards were punched with holes; a signal was sent to the lock to allow it to accept that hole pattern.

I don't recall what vulns were found for that.

@jamesbritt That one sounds like an easy hack just like this.

@ppatel

There was no radio communication. You would need to connect to the wires leading to the lock.
