cosclearance.com is an impersonation phishing page that uses the Costco brand to dangle a free gift card in front of shoppers. Its page is titled "$500 Costco Gift Card Offer", and it targets anyone who recognizes the retailer and clicks through from an ad, text message or social post. PhishDestroy first detected it on 2026-10-05. On 2026-10-19 the domain still existed, but its DNS was inactive and the lure was not loading. The owner could point it at a server again at any time.
How the scam works
Fake retailer giveaways like this usually start with a short survey or "you've been selected" prompt that makes a $500 Costco card feel earned. The victim is then asked for a name, address, phone number and email to "ship" the reward. Often the page also asks for a card number to cover a small delivery or processing fee. That fee is the real payload. The card details can be reused for larger charges or enrolled in recurring billing, and the personal data gets resold or used for follow-up scam calls and texts. No gift card ever arrives.
Evidence
urlscan.io rated the page malicious and recognized Costco branding on it, which matches our classification. On VirusTotal, 7 of 91 engines flagged the domain as of 2026-10-06: alphaMountain.ai, BitDefender, CRDF, G-Data, Gridinsoft, LevelBlue and SOCRadar. That is a modest count, so many browsers and filters may not have warned visitors. The domain also appears in 4 AlienVault OTX threat pulses, and it is listed on the PhishDestroy blocklist.
Infrastructure
The domain was registered through Namecheap on 2026-08-28, about five weeks before we caught it. That lead time is consistent with a domain set up in advance for a campaign. Its traffic ran through Cloudflare, with the address geolocating to Poland. Cloudflare sits in front of a site and hides the real origin server. The site had a valid certificate from Google Trust Services, so the browser padlock showed nothing unusual and gave visitors no reason for suspicion.
What to do
If you entered a card number, call your bank now. Block the card, dispute any charges, and watch for small test transactions or new subscriptions. If you gave your address, phone or email, expect convincing follow-up messages that claim to be from Costco or a courier, and do not answer them. Costco does not hand out $500 cards through clearance sites. Security teams should block cosclearance.com at DNS and the web proxy. They should also search mail and SMS logs for links to it and alert staff, because the domain could start serving the lure again without warning.

Availability, content, DNS and registration are independent evidence layers. NXDOMAIN, an unreachable origin or missing content alone does not prove registrar action. A registrar or provider is credited only when a direct technical marker identifies that actor. Report causality is shown separately.

After a phishing incident
Recomendações e orientações para as vítimas
Choose the steps that match what you shared. Keep a copy of this report alongside your own records.
O que devo fazer agora mesmo?
Urgente
Stop using the suspicious site. Open the real service through its official app or an address you already trust.
Alterar todas as senhas — e-mail, contas do Exchange, qualquer coisa que use a mesma senha
Ativar a autenticação de dois fatores usando um aplicativo autenticador (não por SMS). Desative a recuperação por SMS
Cartões de congelamento se você inseriu dados bancários no site de phishing
Que informações devo coletar para o meu relatório?
Diretrizes do FBI
Keep original emails, receipts, messages and screenshots in a secure place. A factual timeline helps the receiving authority understand what happened. IC3 evidence guidance ↗
Payment records — if you paid, save the receipt, amount, date, payment provider and recipient details.
Datas e horários exatos — de cada transação e do primeiro contato com o golpista
Capturas de tela — sites fraudulentos, mensagens de bate-papo, e-mails, transações em carteiras digitais, redes sociais
Todas as URLs e domínios utilizado pelo golpista (incluindo cosclearance.com)
Comunicações — e-mails, mensagens de texto, números de telefone e nomes de usuário que o golpista utilizou
Mesmo que você não tenha todos os detalhes — registre uma ocorrência mesmo assim. Mesmo informações parciais ainda ajudam nas investigações.
A quem devo denunciar o golpe?
FBI IC3 — Centro de Denúncias de Crimes na Internet (sistema federal de denúncias dos EUA)
Europol — Relatórios sobre crimes cibernéticos na Europa (UE)
Your bank or payment provider — contact its fraud team promptly through official contact details if money or card information was exposed.
Polícia local — cria um registro oficial, mesmo que não possam agir imediatamente
A report is not a guarantee of recovery or investigation, but prompt, accurate transaction data can help authorities and service providers trace the incident.
How do phishing scams typically work?
Sites falsos — clones idênticos, até o último pixel, de sites legítimos, com domínios ligeiramente alterados
Abate de suínos — confiança construída ao longo de semanas pelo Telegram, WhatsApp e aplicativos de namoro; em seguida, o dinheiro foi roubado
Golpes relacionados à recuperação — fraudsters pose as recovery agents and demand upfront fees. Never share a seed phrase or pay before independently verifying the provider
Golpes baseados em IA — deepfakes, phishing automatizado e sites gerados por IA, o que torna a fraude mais difícil de detectar
Como posso me proteger no futuro?
Adicione os sites oficiais aos favoritos — nunca clique em links de e-mails, mensagens diretas ou anúncios
Verificar domínios — verificar PhishDestroy antes de interagir. Verifique se o site usa HTTPS, a ortografia e a idade do domínio
"Bom demais para ser verdade" = golpe — retornos garantidos, endossos de celebridades, prazos urgentes
