My oldest daughter recently accepted an offer to attend Purdue University. The following week we received a package in the mail containing a canvas laundry bag with the Purdue logo emblazoned on the side. We didn’t recognize the sender’s name or address, so we did a little Googling but that didn’t help much either. It was then that I remembered reading an article about a relatively new scam called “brushing.” We rechecked the package, and sure enough, there was a tell-tale QR code printed on the side. Had we scanned that code to see who had sent us this nice gift, personal phone data would likely have been immediately compromised.
