Hotel keycards can be easily hacked in 200 milliseconds


Hotel Key Card

With less than $50 of store-bought hardware and some programming, a hacker can gain instantaneous and untraceable access into over four million hotel rooms around the world, according to Cody Brocious, a Mozilla software developer.

He details his findings on his website. The time it takes once installed: around 200 milliseconds.

“With how stupidly simple this is, it wouldn’t surprise me if a thousand other people have found this same vulnerability and sold it to other governments,” said Brocious. “An intern at the NSA could find this in five minutes.”

  1. Nice video.  One correction: the port isn’t actually used for charging at all — the batteries are just standard AAs — but rather is used purely for communication.
