Stealing Money from a ATM using a MP3 Player
According to TIMES a fraudster outwitted sophisticated banking security systems by using an ordinary MP3 music player to bug cash machines and steal customers’ credit card secrets.
The fraudster or other gang members would use MP3 portable music players to record data transmitted from free-standing ATM cash machines. The data was then converted to readable numbers using a separate computer programme.
The phone line running from the machine to an ordinary BT white socket was unplugged and a two-way adaptor inserted. The MP3 player was then placed between the ATM machine’s output cable and the phone socket.
The player would record the tones, which resemble the kind of sound emitted by a fax machine.
[...]
The gang targeted freestanding ATM machines in bars, bingo halls and bowling alleys.

Wow! Being in the atm business myself, I can see how this can easily be done. Very rarely would an atm owner look at the phone line. Only if the transactions were not going through. In the article above, it seems that they are!
