Then we would send it a serial string that we knew the answer to вЂ¦ Our app sends those, and if it gets a response back that is similar to, then we tell the user this is for sure a skimmer, move on to a different gas pump. What our app did, that was above and beyond that, is that if it saw a radio that we already knew was a skimmer, or suspected was a skimmer because it was the type of radio would use, then we would connect to it over the serial protocol. So in theory, you can open up your cellphone, go to вЂњscan for Bluetooth devicesвЂќ and possibly you would see the Bluetooth radio that was in the skimmer.

And with the particular skimmers that we came into contact with, we found that didnвЂ™t even change the default name or password of the Bluetooth unit.

With some of these gas pump skimmers that weвЂ™ve come across, they will use a very common Bluetooth radio вЂ¦ and you can see it as a device that you would connect your phone to, just like a Bluetooth speaker or anything else like that. Poole explained that he and his colleagues were consulted by local law enforcement in Colorado after a wave of credit card skimmer thefts at gas stations in 2017 and were able to reverse engineer some of the skimmers removed from the pumps, adding that:

We asked Nick Poole, an electronics expert at the hobby electronics company SparkFun and co-creator of the вЂњ Skimmer ScannerвЂќ Android app, to outline how they work. Not all credit card skimmers operate using Bluetooth technology in this way, but many do, and this use of Bluetooth technology is what leaves the skimmers vulnerable to detection. The thieves who planted the skimmer can then return to the machine and use a Bluetooth transmitter to transfer all the stored credit card details from the skimmer to a storage device such as a mobile phone or laptop, all without having to physically remove the skimmer. When a customer inserts a card into the reader, the transaction takes place as normal and the customerвЂ™s card is debited, but the skimmer also extracts all the relevant data from the magnetic stripe on the card, including the credit card number, expiry date, and security code.

(The Facebook post confusingly referred to a вЂњcard readerвЂќ rather than a вЂњcard skimmer.вЂќ) The warning is related to a particular kind of credit card skimmer that is placed in a credit card reader at an ATM or gas station pump. This warning was a somewhat crude explanation of a real phenomenon: the Bluetooth sensor on a mobile phone can indeed be used to detect some - though by no means all - credit card skimmers at gas pumps and ATMs.
