💅 MFOC — the manual, but make it cute

okay bestie, so this is the mfoc manual page from the General Commands Manual section, and it's lowkey iconic. Also it's manual page MFOC(1) if you're keeping score. Let's get into it. 🦋

✨ NAME ✨

mfoc — a MIFARE Classic offline cracker. yes fr fr, that's the whole name section. short, sweet, ate. 💅

🎀 SYNOPSIS 🎀

mfoc [ -h ] [ -k KEY ]...  [ -O FILE ] [ -P NUM ] [ -T NUM ]

that's it. that's the vibe. brackets everywhere because everything is optional-ish, iykyk. ✨

🦋 DESCRIPTION 🦋

so this manual page documents the mfoc command briefly — that's literally what the original says, it's giving humble. 🙈

mfoc is a program that cracks the encryption of a MIFARE Classic chip and dumps the chip's keys and decrypted memory contents to a file. like, it takes the secrets and hands them to you. main character energy tbh. 👑

to run it you need:

  • access to an NFC reader — no reader, no vibes, no cracking. 🫶
  • a card equipped with a MIFARE Classic chip — and of course the card. like, you can't crack a card you don't have. obviously bestie.

🌸 OPTIONS 🌸

a summary of options is included below. every single one, no skips, no cap.

  • -h — show a summary of options. the "help me bestie" flag. 💖
  • -k KEY — initially try KEY in addition to the default keys. so you're not replacing the defaults, you're stacking them. more keys, more chances, more slay. 🔥
  • -O FILE — dump the card contents to FILE. this is where the goodies go. 🍓
  • -P NUM — probe each sector up to NUM times. default is 20. persistent queen behavior. ⭐
  • -T NUM — set half the range for a possible distance tolerance to NUM. default is 20, which gives you a total range of 40. math is math. 🧚
reminder bestie: -P and -T both default to 20, and for -T that 20 is only half the range — the full range is 40. don't let that trip you up. 💀
