Fake auction scam：手法、警示信号与应对

Shopping scams · alto

Fraudsters build sites mimicking official auctioneers or invent them, complete with vehicle photos, auction notices, company IDs and even a real auctioneer's name copied from public registries. Sponsored social media ads drive traffic.

The victim registers, bids and "wins" an item at a very attractive price. They receive a winning notice and a short deadline to pay via Pix or boleto to a personal account or a company unrelated to the auction.

After payment, extra fees appear (storage, paperwork) and eventually the site disappears.

Sinais / Signs

Price far below market value.
Payment to a personal account or a company ID different from the auctioneer.
Very short payment deadline and pressure not to lose the item.
No way to visit the yard or inspect the item in person.
Newly registered domain or one resembling a known auctioneer.
Contact only via WhatsApp.

Prevenção / Prevention

Check with the state commercial registry that the auctioneer is registered and that the site is theirs.
Call the number on the official registry, not the one on the site.
Visit the display location before bidding.
Pay only into an account linked to the auctioneer as stated in the notice.
Be wary of sponsored auction ads with unrealistic prices.

O que fazer / What to do

Call your bank right away using the official number (back of the card or in the app) and ask to block cards, accounts and access.
If you paid via Pix, ask your bank to open a MED (Special Return Mechanism) claim as soon as possible — time matters because funds move fast.
File a police report (many Brazilian states accept online reports) and keep screenshots, receipts, numbers and links.
Report the site to the commercial registry and to the auctioneer whose name was used.
Report the profile, ad or number to the platform (social network that ran the ad) so it gets taken down and others are protected.

FAQ

How do I know an auction site is legitimate?

Check the auctioneer with the commercial registry, confirm the site address by official phone and distrust payment to third parties.

Is a very cheap car at auction a scam?

Not necessarily, but a far-below-market price plus urgency and payment to a third party is the fake-auction pattern.
