future. >> were you surprised? and i know it wasn't easy, but were you surprised that you were able to pull it off? >> i was a little surprised. you know, when you look at an atm, it looks like a somewhat impennetable device. and you think about atm security, and you typically think about physical defenses, right? is the atm bolted down, are there cameras in place? this is the first time anyone had actually looked at the underlying software. and once i sore of dug in, ripped the software apart, i was really surprised at the amount of flaws hiding underneath there. >> all right, barnaby, two more things. maybe put some of our minds at ease. you worked on this for quite some time, but you know how difficult it is to pull this off. so in your estimation, are there very few guys out there? you know, people always try to get into an atm, hackers and what not, but in your estimation, are there very few who could possibly pull this off? >> yeah. and it would take a bit of time to replicate. of course, i'm not naive enough to think i'm the only person who could do it.
