I got a package from Amazon that I did not order. It was in a red box with a business card that had a QR CODE. I looked at my order history and I didn't see it and I knew I didn't buy it. I called Amazon and they said this is a SCAM and when you scan the QR code the scammers get access to everything in your phone.
The Brushing Scam

A "brushing scam" on Amazon is when a seller sends unsolicited packages to random customers, often containing cheap or insignificant items, with the goal of creating fake positive reviews to artificially inflate their product ratings and boost sales on the platform, even though the recipient never ordered anything; essentially, they are "brushing" up their product's appearance with fake positive feedback by sending out seemingly random packages to generate reviews based on a false purchase.
