Gas Pump Skimmers
Resources and Going Further
We hope you enjoyed reading this in-depth teardown of these scary devices. If you'd like to assist us, we are curious to answer the following questions:
What do these devices actually cost? We haven't trolled the dark web far enough to find one.
What types of fuel pumps do the skimmers work on? It's unclear if this model of skimmer works across the field or if it works only with certain pump types.
What are some other methods for detection and prevention? We brainstormed all sorts of things. In the end, it's shocking how easy it is to open up a gas pump. The quickest prevention method we could think of was a klaxon attached to a leaf switch set to go off anytime the pump is opened. Provide all pump repair folks with ear protection and the problem of skimmers is solved.
