You don’t need an anonymous hacker from the internet to steal your valuable credentials. Sometimes bigger risks lie inside your local convenience store. There are some indiscreet people who try to steal your credit card information while you’re purchasing something from your local convenience store. It happens a lot, particularly in the gas pumps. There are a lot of credit card skimmers, recording and storing your credit card information for further use. However, there’s an app called Skimmer Scanner that detects if there’s any skimmer nearby.
What’s more concerning about those credit card skimmers that those are extremely easy to install at the end of a selling point; it takes less than 30 seconds to install those devices. It records your credit card data while you swipe it, which the perpetrator can retrieve hours, or even days later using a mobile or laptop.
Nathan Seidle, CEO of the website SparkFun described those pump skimmers on his blog. He was sent some of those skimmers by the local law enforcement. Most of them use a Bluetooth connection that can easily be detected.
“Initially this blew my mind,” he wrote. “If I were to design a Bluetooth skimmer I would program the module to NOT broadcast its ID.”
The Skimmer Scanner app can alert you if there’s any credit card skimmer nearby by checking for nearby Bluetooth connections. The app is currently available only on Android. However, its code is open source for anyone to tinker with.
