kodera.jp is classified by PhishDestroy as an impersonation phishing page. Its page title presents it as 小寺歯科医院, a dental clinic in Sanda, Hyogo Prefecture, advertising bad-breath treatment, pediatric dentistry and implants. That local, trustworthy-sounding identity is what visitors see first, even though we classify the domain as impersonation. PhishDestroy first flagged it on 2026-09-20, and as of 2026-10-19 the site was still online and its content resolved through a redirect.
How the scam works
Impersonation phishing borrows the name and look of an organization people already trust, then steers them toward a form or page where they hand over something valuable. That is usually login credentials, personal details or payment information, which the operators then reuse or sell. Here the domain currently answers with a redirect, so a visitor who arrives expecting a clinic's website can be passed on to a different destination without noticing.
Evidence
On 2026-09-29, 15 of 91 VirusTotal engines marked the domain as malicious or phishing. The vendors include ADMINUSLabs, alphaMountain.ai, BitDefender, Chong Lua Dao, CyRadar, ESET, Forcepoint ThreatSeeker and Fortinet, a mix of commercial antivirus firms, URL-reputation services and a community anti-scam group. The domain also appears in 32 AlienVault OTX threat pulses, so many independent researchers have tied it to malicious activity. Among the blocklists tracked here, it is listed by PhishDestroy.
Infrastructure
The domain was registered on 2006-06-27, roughly twenty years before PhishDestroy flagged it. That makes it an aged, long-standing name rather than a throwaway domain created for a single campaign, and it explains why reputation filters may have trusted it. It is hosted in Japan on the KDDI CORPORATION network, which fits the local business named in its title.
What to do
If you followed a link to kodera.jp and typed in a password, change it right away on every site where you use it, and turn on two-factor authentication. If you entered card or banking details, contact your card issuer to block the card and watch your statements for unfamiliar charges. Treat any later emails or messages that refer to the clinic or to your visit with suspicion. Defenders should block the domain and anything it redirects to, search proxy and DNS logs for users who reached it after 2026-09-20, and reset credentials for anyone who submitted a form there.

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
