Have you recently received an Amazon package that you didnt order? It may be part of a scam called brushing.
This scheme involves an unordered package from Amazon showing up at your doorstep with your name on it.
Legally, you get to keep any package thats addressed to you, but this scam isnt entirely a victimless crime.
Third-party online sellers engage in brushing scams in an attempt to raise product ratings on websites such as Amazon. The seller pays a third party to purchase their products through fake buyer accounts theyve created.
After the purchase, the item gets delivered to a real address. Then the seller can write a positive review of their own product from the fake Amazon buyer account.
Receiving unordered packages from Amazon means your information has been compromised. A third-party seller somehow acquired your name, shipping address and possibly your Amazon account information. (HOPEFULLY NOT)
Amazon provides a help page for victims of brushing scams.
