Unknown Amazon Packages are making a comeback
Amazon sometimes suffers from data breaches or users are using the same logins and passwords on multiple sites and they become compromised. Financial information such as debit or credit cards are normally encrypted. Logins and passwords are normally sold on blackmarket websites, hundreds of thousands are sold for a few thousand. This has created a modern concept called brushing, where you receive packages from Amazon, normally from China, with no return address. Once you receive them, bad actors are using your confirmed purchase to write positive reviews of their products. This is why sometimes when you are browsing Amazon, there are nonsensical reviews, and even reviews of completely different products.
