네트워크 보안 인텔리전스 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.

How do phishing scams typically work?
가짜 웹사이트 — 도메인을 약간만 변경한, 정식 사이트와 픽셀 단위로 완벽하게 일치하는 복제 사이트
pig butchering — Telegram·왓츠앱·데이트 앱을 통해 몇 주에 걸쳐 신뢰를 쌓은 뒤, 돈을 훔쳐갔다
회복 사기 — fraudsters pose as recovery agents and demand upfront fees. Never share a seed phrase or pay before independently verifying the provider
AI를 이용한 사기 — 딥페이크, 자동화된 피싱, AI로 생성된 사이트 등으로 인해 사기 행각을 적발하기가 더 어려워지고 있다
앞으로 어떻게 하면 스스로를 지킬 수 있을까요?
