ATM Hacking is fairly easy. Two or three hours research will get you the basic information you need.

Like any other computer system, they all have factory default passwords for management functions. So you get the make and model and find the manual.

Here's what's going to happen.

You log on and re program the thing to think the stack holding the $20 or $100 if you're lucky, to believe Is the slot for the $10. Now you pop in your debit card and request $10 and get a 20. W00t!!!

HACK THE PLANET!

Oh yea you are on camera.

This will not work at a banking facility.

If you really want to steal, some of the older machines, still in use EVERYWHERE, have internal HDD's

Logg on to the ATM, use a straight through cable and copy the data from the HDD to your laptop. You'll have a days worth of account #'s and PINs Usually in PLAIN TEXT.

You'll need an impressive looking uniform. An ID badge usually helps (Don't use your real name)
Another good place to get cc#'s and pins are gas pumps. Smash and grab the HDD's
