Listing Hijacker

A listing hijacker is an unauthorized third-party seller who attaches to your Amazon ASIN — often selling counterfeit, gray-market, or undercut units — to steal your Buy Box, siphon your sales, and erode your brand reputation.

How Listing Hijacking Works

  1. A seller finds your live listing on Amazon.
  2. They click Sell on Amazon and match your ASIN, listing under the same product page.
  3. Their offer competes for the Buy Box, usually by undercutting your price.
  4. Shoppers buy from them expecting your brand quality.
  5. Negative reviews, returns, and A-to-z claims land on your listing.
