How to spot a Point Of Sale "Skimmer" device

A "Skimmer" is a device that criminals use to modify ATMs and POS terminals at store checkout lanes.  These are bad because they capture the account information from your card as well as any numbers that you enter on the key pad (e.g. your bank account PIN).  They then pass that to the real POS device that they are installed on top of, while recording your information.

Since skimmers can be installed incredibly quickly, this attack is a real threat when you use your card to buy groceries or whatever.

Brian Krebs has an outstanding article on how to recognize that one of these has been installed.  Highly, highly recommended to all Borepatch readers.

At least in my area they keep finding skimmers riding man in the middle INSIDE the gas pumps.

Since they all use the same keys, and even if its rekeyed a tubular lock pick is cheap and easy to use, its easy to get these installed inside.

Then there is nothing you can do, nothing to see external, and it swipes you're card as you fill up. All the more reason to watch your account like a hawk
