I have a tendency to pull on things like ATM covers, credit card slots, and the like. And that's because we have lots of skimmers that are found at local gas stations and places around here (big college presence).
So far, I've found an opened gasoline pump door. I called attendant and went to a different pump (attendands didnt have keys for that....) .
Ive also found an ATM that was partially locked and came opened when I gave it a tug. I called our bank's security after that one.
I also found a skimmer on a gas pump as well. It had a fishy look to it and gave it a tug. Pop. Was just a simple card reader and cam module in 1. I harvested the parts and put the microsd card through a good format.
