The company I work in switched to a new building, and we have those stupid doors with RFID cards on them. I’d be damned if I’m going walk with that I’m-working-in-hightech-company-card dangling of my belt. I wonder if there is a way for me to use my phone for credentials. I tried searching for it, and all I could find is ways for me to use the phone in order to copy the info from one card to another.
So is it somehow possible?
Nfc in your phone is not RFID.
What one pen tester did was plant a RFID chip in his hand so when he clones a card he can use his hand instead of the card. He walks around the building with a regular card on display buy his hand has a security guard code allowing him access anywhere on a job site.
“Summer hacker camp” is on at the moment in Las Vegas ( Defcon and blackhat), you can keep an those conferences for any emerging tools for this kind of thing.
