komainuclientcustody.com presents itself as "Komainu Client Custody" and borrows the name of Komainu, a digital-asset custodian that serves institutional clients. The domain does not belong to the real company. It is built to look like a client-facing custody portal and aims at funds, family offices and other holders who would expect to log in to such a service. PhishDestroy first flagged it on 2026-09-30. Its live status could not be confirmed as of 2026-10-19.
How the scam works
Fake custody portals copy the look of a trusted custodian so that a client lands on a convincing "client custody" sign-in or onboarding screen. Victims are pushed to enter account credentials, two-factor codes or identity documents. In some versions they are also told to move assets to deposit addresses that supposedly belong to the custodian. Whatever is typed or sent goes to the operators. Losses can include custody account access, sensitive corporate KYC material and any crypto transferred under the pretext of safekeeping.
Evidence
Detection is still thin. On 2026-09-30, 2 of 91 VirusTotal engines flagged the domain, alphaMountain.ai and CRDF, so most scanners will not warn a visitor yet. The stronger signal comes from crypto-specific defenses. Besides PhishDestroy, MetaMask's phishing list and the SEAL blocklist both carry the domain. One AlienVault OTX threat pulse also references it.
Infrastructure
The domain was registered through NameCheap, Inc. on 2026-09-21 and was flagged nine days later. That short gap is typical of a lookalike name set up for a specific campaign. The site sits behind Cloudflare, Inc., with the address geolocating to Canada. This reflects the proxy network and says nothing about where the operators or the origin server are located.
What to do
If you entered a username, password or 2FA code here, change the password on the genuine Komainu account at once. Reset two-factor authentication, end active sessions, and alert your Komainu relationship contact so they can watch for unauthorized activity. If you uploaded identity or company documents, treat them as exposed and warn your compliance team. If you sent assets to an address shown on this site, record the transaction hashes and report them to the custodian and law enforcement. Do not pay any "release" or "verification" fee that follows. Defenders should block the domain at DNS and the mail gateway. They should also hunt in mail and proxy logs for clicks since 2026-09-21 and warn staff who handle custody operations about lookalike Komainu domains.

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
