A hijacker does not announce themselves. One morning your Buy Box is shared with a seller you have never heard of, your price is undercut by four dollars, and your review count has not moved but your unit velocity has dropped by a third. By the time you notice, they may have been running for a week. On Amazon, brand protection is not a one-time registration task. It is a standing operation, and the brands that treat it that way lose far less margin, less rank, and less sleep.

Why This Is an Account Health Problem, Not a Legal One

Most brand owners file this under "eventually, if it becomes a problem." That is backwards. A hijacker selling counterfeit or gray-market units against your listing does three things immediately: it splits your Buy Box, it can trigger returns and complaints tied to your ASIN even though you never touched the inventory, and it drags your review average down with product that was never yours. Amazon does not distinguish between "your fault" and "someone else's fault" when a listing's performance metrics slip. The account sees the damage and treats it as yours.

This is why brand protection sits next to the other quiet threats we cover in stranded inventory and other silent revenue leaks. Nobody emails you when it starts. You have to go looking, or build something that looks for you.

Set Up Monitoring Before You Need It

Waiting until sales dip to check for hijackers means you already lost the week or two it took to notice. Build monitoring into your weekly routine instead.

Brand Registry and Transparency. If you are not enrolled in Brand Registry, that is step one, full stop. It unlocks the reporting tools and takedown paths everything else in this post depends on. Transparency codes go further: unit-level serialization means a counterfeiter physically cannot fulfill an order without a valid code, which stops the problem at the source rather than after the fact.

Buy Box ownership checks. Set a recurring check, at minimum weekly for your top revenue ASINs, on who holds the Buy Box and who else is listed as a seller on your listings. A new seller name appearing on your product page is the single clearest early signal.

Price and offer alerts. A hijacker selling counterfeit product usually prices to move fast, often below what a legitimate margin allows. A sudden low-ball offer next to your listing is worth investigating the same day, not the same month.

Review and return pattern shifts. Watch for a cluster of complaints about a defect you know is not in your current production run: wrong packaging, missing accessories, a different label. That is often the first customer-facing evidence of counterfeit units in the wild, arriving before you see it in the Buy Box.

The brands that catch hijackers in a day, not a month, are the ones who built the check into a routine instead of waiting for a symptom to force the issue.

Document Everything the Moment You See It

When you spot a suspicious seller, resist the urge to report immediately with a half-built case. Amazon's enforcement teams move faster and more decisively on complete submissions. Before you file anything, capture:

This is the same discipline that matters when you are contesting a listing suppression. As we covered in what to do the day your listing gets suppressed, Amazon's review teams respond to specific, well-documented submissions far faster than vague complaints. A hijacker report is no different: the tighter the file, the faster the resolution.

Use the Right Tool for the Right Threat

Amazon gives you several distinct reporting paths, and using the wrong one slows everything down.

Report a Violation through Brand Registry is the right first move for most hijacking and counterfeit cases. It routes directly to the enforcement team that handles IP and listing integrity issues, and Brand Registry members get priority handling here.

Test Buy program lets you purchase directly from a suspect seller specifically to build a counterfeit case, and Amazon covers the cost of qualifying purchases. Use this when you strongly suspect counterfeit but do not yet have a physical unit to compare.

Project Zero is worth evaluating if hijacking and counterfeiting are a recurring pattern for your brand rather than a one-off. It gives you the ability to remove counterfeit listings directly using your own scan-based technology, without waiting on an Amazon investigation for every instance.

Match the tool to the severity. A single suspicious seller with no purchase evidence yet is a Report a Violation case. A recurring pattern across multiple ASINs is a Project Zero conversation.

Protect the Listing Itself, Not Just the Buy Box

Hijackers and counterfeiters exploit weak listings as much as weak enforcement. A listing with thin backend content, no A+ modules, and generic imagery gives a bad actor more room to blend in unnoticed. Strong, distinctive brand content, the kind covered in A+ Content that sells, makes your authentic listing visibly harder to imitate and easier for customers, and for you, to recognize when something is off. The same logic applies to your hero image and packaging photography: distinctive, hard-to-replicate creative is a quiet form of brand protection, not just a conversion lever.

What to Do This Week

Pick your top ten ASINs by revenue and do three things before Friday: confirm Brand Registry and Transparency enrollment is current for each, set a recurring calendar check for Buy Box ownership and offer listings, and build a simple documentation template so you are not starting from scratch the next time something looks wrong. None of this takes more than an afternoon, and it is the difference between catching a hijacker in a day and finding out three weeks later why your numbers slipped.
