Watch it. Then pledge. It's never gonna be this cheap again. 👇 indiegogo.com/projects/rfidr… #Proxmark5 #RFID #NFC #HardwareHacking

Everything in the Proxmark3 Iceman firmware. Every iCLASS, SEOS, Mifare, UL-AES, FeliCa update. Every late night debugging session. None of it is sponsored. All of it is open source. If it has saved you time or taught you something, consider buying me a coffee. Patreon this week: promo code 82409 for a discount. patreon.com/iceman1001 #Proxmark3 #RFID #OpenSource #InfoSec

Remembering the greatest security blog post tool of all time: magspoof by @samykamkar It demos a wireless credit card spoofer that: •Allows you to store all of your credit cards and magstripes in one device •Works on traditional magstripe readers wirelessly (no NFC/RFID required) •Can disable Chip-and-PIN •Correctly predicts Amex credit card numbers expirations from previous card number (code not included) •Supports all three magnetic stripe tracks, and even supports Track 1 2 simultaneously •Easy to build using Arduino or other common parts
