Scouting report
Cracked GSM’s A5/1 encryption with rainbow tables, showed millions of SIM cards could be hijacked over the air with a text message, broke Mifare smartcards, and with Jakob Lell released BadUSB — proof that any USB device’s firmware can be reprogrammed to lie about what it is.
Curator’s note
If it has a radio and a chip, he has probably already read the datasheet.
