gempai.app is an impersonation phishing page that presents itself as a playful Japanese tool for generating sparkly mahjong hands. It is listed by the MetaMask and SEAL blocklists, which points to crypto wallet users as the likely targets. PhishDestroy first flagged it on 2026-10-07, three days after the domain was registered. As of 2026-10-19 the site was still online and serving content.
How the scam works
The page title, "Gem牌 | キラキラ麻雀牌姿ジェネレーター", promises a "sparkly mahjong hand generator", while our classification is impersonation phishing. Schemes of this kind copy the look or identity of a trusted service so visitors lower their guard, then steer them to an action that hands over control: typing a password or seed phrase, or connecting a wallet and signing a request. Anyone who complies can lose account access or have funds moved out of their wallet.
Evidence
Nine of 92 VirusTotal engines flagged the domain on 2026-10-11. The vendors include alphaMountain.ai, BitDefender, CRDF, Forcepoint ThreatSeeker, Fortinet, G-Data, Gridinsoft and Kaspersky. Most engines have not flagged it, but these detections come from independent sources. MetaMask and SEAL both list the domain alongside PhishDestroy, so wallet software that relies on those lists may warn users before the page loads. Four AlienVault OTX threat pulses also reference the domain, showing it is being tracked by researchers outside our project.
Infrastructure
The domain was registered on 2026-10-04 and caught within three days, which fits the short life of disposable phishing domains. It was registered through CloudFlare, Inc. and sits behind Cloudflare's network (AS13335), with the address resolving to the US. Because Cloudflare acts as a proxy, the visible IP belongs to the network edge rather than the operator's real server.
What to do
Do not enter any credentials, recovery phrases or private keys on gempai.app. If you connected a wallet or signed anything there, revoke the site's token approvals with a trusted approval-checking tool. Move remaining assets to a fresh wallet if you shared a seed phrase. If you typed a password, change it everywhere you reused it and turn on two-factor authentication. Defenders should block the domain at DNS and proxy level and report it to Cloudflare's abuse channel. They should also check logs for users who visited after 2026-10-04.

Registrar accreditation and DNS abuse obligations
For this gTLD, the registrar above operates under an ICANN accreditation agreement. The links below provide the official fee schedule and current DNS abuse compliance guidance.
Accreditation is a contract, not a safety certification.
RAA §3.18 establishes abuse-contact and handling requirements. This report can document stored outbound notices and later technical observations; it does not by itself establish receipt, investigation, remediation, or contractual non-compliance.

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
