Return to sender: Surprise! A package you never ordered landed on your porch. A 75-year-old Missouri woman keeps getting them, including silverware from TikTok Shop. It’s called brushing, and the FBI warns the nasty new version tucks a QR code inside. Scan it, and you land on a fake site built to steal your passwords and credit card numbers. My rule: Never scan a code or call a number from a mystery box. Toss the note. Don’t let them QR-code your Christmas.
