网络安全情报 Registrar context
Registrar contextTrustname
Stored registration data identifies Trustname / Fewmoretaps OÜ (IANA 4318) as the registrar. PhishDestroy maintains a separate registrar investigation; that material is contextual and is not an independent detection for this domain.
costsavingus.com is a phishing page that presents itself as "Sam's Club Store Rewards," aimed at shoppers who recognise the warehouse-club brand and expect a genuine loyalty perk. The domain name contains no Sam's Club branding, so visitors usually arrive through a link in an ad, text or email rather than by typing it in. PhishDestroy first flagged it on 2026-09-05. The site was still online and serving its content when last checked on 2026-10-19.
How the scam works
Fake store-reward pages typically tell the visitor they have been selected for a prize or member reward, often after a short survey designed to build trust and urgency. To "claim" it, the victim is asked for a name, address, phone number and email, and frequently for card details to cover a small shipping or processing charge. Those card details can then be used for unauthorised charges or recurring subscriptions, and the personal data feeds follow-up phishing. No real Sam's Club reward is ever delivered.
Evidence
On VirusTotal, 5 of 92 engines flag the domain as of 2026-10-18: alphaMountain.ai, Forcepoint ThreatSeeker, Gridinsoft, Netcraft and SOCRadar. That is a low count, so many browsers and filters will still let the page load without a warning. The domain also appears in 4 AlienVault OTX threat pulses, which shows other researchers have tied it to malicious activity. PhishDestroy lists it on its own blocklist.
Infrastructure
The domain was registered on 2026-07-04 through Fewmoretaps OU d/b/a Trustname.com, about two months before PhishDestroy detected it. That gap fits a domain held in reserve before a campaign starts. The site runs on 185.66.141.35 in the KnownSRV Ltd. network in the Netherlands. Its free Let's Encrypt certificate means the padlock icon proves nothing about who runs the site.
What to do
If you entered card details, contact your bank or card issuer right away, cancel the card and dispute any charges you don't recognise, including small recurring ones. If you gave your address, phone or email, expect convincing follow-up messages claiming to come from Sam's Club or a delivery company, and don't act on them. Check rewards only through the official Sam's Club app or website. Defenders should block costsavingus.com and its IP at DNS and proxy level, and search mail and SMS logs for links to it.

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.

我应该为报告收集哪些信息？
联邦调查局（FBI）指南
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.
Your bank or payment provider — contact its fraud team promptly through official contact details if money or card information was exposed.
当地警方 — 即使无法立即采取行动，也能留下正式记录
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?
虚假网站 — 与正规网站完全一致的克隆网站，仅域名略有改动
猪的屠宰 — 通过Telegram/WhatsApp/交友软件花数周时间建立信任，随后钱被骗走
退款诈骗 — fraudsters pose as recovery agents and demand upfront fees. Never share a seed phrase or pay before independently verifying the provider

A capture documents what was shown. A scanner result records that provider’s assessment at the time of its check. Neither a valid certificate nor a zero-detection result is a guarantee of safety.
