cleaningbusinessinstitute.com presents itself as an online school, titled "Cleaning Business Training & Certification Online". PhishDestroy classifies it as an impersonation phishing page aimed at people looking to start or credential a cleaning business. We first flagged it on 2026-10-10. As of 2026-10-19 the site was still online and serving its content.
How the scam works
Impersonation sites like this borrow the look and authority of a legitimate training provider or certification body so that sign-ups and payments feel routine. Visitors are typically asked to create an account, enter personal and contact details, and pay for a course, exam or certificate through checkout forms the operator controls. The victim can lose the fee, card or banking details, the account password they chose, and identity data that can be reused in follow-up fraud. The page title describes a training and certification service, while our classification is impersonation phishing.
Evidence
On 2026-10-16, 18 of 92 VirusTotal engines flagged the domain. Vendors included BitDefender, Fortinet, Dr.Web, Forcepoint ThreatSeeker, alphaMountain.ai, Criminal IP, CRDF and the Vietnamese anti-scam group Chong Lua Dao. That is a substantial number of security vendors reaching the same verdict on their own. The domain also appears in 34 AlienVault OTX threat pulses, which shows other researchers have been tracking it, and it is listed on the PhishDestroy blocklist.
Infrastructure
The domain was registered through NAMECHEAP INC on 2025-03-03, about nineteen months before PhishDestroy detected it. A long-held name like this can pass quick age-based reputation checks that would catch a newly registered domain. The site resolves to Cloudflare (AS13335) in the US, so the real origin server is hidden behind the proxy network.
What to do
If you paid this site for a course or certificate, contact your card issuer or bank immediately to dispute the charge and ask for the card to be replaced. If you created an account, change that password everywhere you reused it and turn on two-factor authentication for your email. Expect follow-up messages that pretend to come from the "institute" or a certification body, and do not respond to them. To confirm whether a cleaning certification is real, go directly to the issuing organisation's official site. Security teams should block the domain at DNS and web proxies, search logs for staff visits or form submissions, and report it to Cloudflare and Namecheap so it can be taken down.

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
