You can buy an ATM card skimmer on Alibaba
This is so messed up! Remember that video of the very sketchy ATM card skimmer in Vienna? Well, it turns out that Alibaba is selling that exact device on their website. The product doesn't include the electronics needed to skim data from a card, but the mold itself is already such a head start for somebody who is looking to do some real damage at an ATM.
