Some might call you paranoid, but who cares. You’re taping up your webcam in the name of security, and you’re checking the ATMs you use to spot skimmers. At least, you should be. If you’re not, then you could very well be a fraud ring’s next victim — but we’ve established that’s not you, right? You’re ever-vigilant like Benjamin Tedesco, and your Spider-sense will save yourself — and a lot of other people — a whole lot of headaches.Tedesco, who is part of the elite cybersecurity team at Carbon Black, was vacationing in Venice this month. Like a lot of tourists, he needed to hit an ATM to withdraw a little local currency. Rather than just whipping out his bank card and jamming it carelessly into the machine, he took a moment to do a quick visual inspection. It’s a good thing he did, too, because Tedesco immediately noticed that there was something fishy about the card reader. There was a bit of glue residue around its perimeter, which was enough to arouse his suspicions. He grabbed hold, gave it a tug, and off it came.Apart from the giveaway glue, the skimmer was a perfect match for actual card reader it was obscuring. Being the responsible guy that he is, he recorded the whole thing to share with the rest of us — and further stoke the fires of justified paranoia.Tedesco didn’t stop with a video warning for the rest of us to heed. When another tourist approached the adjacent machine, he jumped in before she had a chance to insert her card and gave the reader a good tug to make sure it was legit. Well done, sir!
