It wasn't a very easy process. I had to scan my card for about 30 minutes and then I had to scan the card reader for a bit. It was impractical.

- lxgr 3y agoInteresting, do you happen to know what system that was? Sounds like an active attack of some sorts.
- hnav 3y agoSounds like something based on NXP Mifare Classic. You first try a dictionary attack against the fob (most readers use whatever default keys the vendor set), if that fails, you collect nonces by touching the flipper to a reader, calculate keys in the companion app on your phone, then add keys to the flipper's dictionary. The attacks are called darkside and nested.
