Confidence

www31.tracer.jp was originally a legitimate log-collection subdomain operated by NTT Com Online for their Visionalist web analytics service until July 2020. After the domain expired, a third party re-registered it in May 2022 and immediately began hosting malicious scripts. NTT Com issued formal warnings that any website still embedding the old Visionalist tracking script would execute code from this hijacked domain, risking data exfiltration and unauthorized redirects. Two antivirus engines (ADMINUSLabs and Kaspersky) flag the domain as malicious. The incident is documented in technical security literature as a case study in "zombie" SaaS domain abuse. No legitimate business operates this domain today.

Full dossier

Analysis complete

Page Content

The domain hosts malicious JavaScript intended to be loaded by legacy tracking implementations. Websites that embedded the original Visionalist tracking script <script src="https://www31.tracer.jp/VL/..."></script> would execute attacker-controlled code.

Infrastructure

Hosted on a third-party server after domain re-registration in May 2022. No legitimate SSL or WHOIS data available for analysis.

Domain History

Originally registered to NTT Com Online (Japan) as a subdomain of tracer.jp for the Visionalist analytics service. Service discontinued July 2020. Domain expired and was drop-caught by a Turkish-named entity ("Yazılım Hizmetleri") around May 5, 2022, at which point malicious scripts were deployed.

Web Reputation

Flagged by antivirus engines ADMINUSLabs and Kaspersky as malicious. Documented in NTT Com security advisories, ITmedia news coverage, and academic security research on hijacked SaaS domains. No positive reputation signals.

Risk Factors

Confirmed malicious by 2 antivirus engines (ADMINUSLabs, Kaspersky).
Domain hijacked after legitimate service expiration and re-registered by unrelated third party.
Hosts malicious scripts designed to exfiltrate data from websites embedding legacy tracking code.

Targets websites that have not updated or removed old Visionalist tracking implementations.
Re-registration by Turkish-named entity with no legitimate business connection to original service.
Incident cited in academic security research as case study in SaaS domain abuse.

AI Recommendation

Do not visit this domain. If you operate a website that embeds the old Visionalist tracking script, remove it immediately to prevent execution of malicious code. Report any suspicious activity to your hosting provider.

Research summary

Narrative write-up from our AI analyst, grounded on the facts above

NTT Com Online (the original operator) issued formal security warnings in May 2022 documenting that tracer.jp had been hijacked after service discontinuation. The domain was re-registered by a third party and malicious scripts were placed on it. ITmedia published a news article titled "提供終了したアクセス解析ツールのドメインが他者の手に　不審なスクリプトが設置されている可能性も" ("Discontinued analytics tool domain now in others' hands; suspicious scripts may be installed") covering the incident. NTT Com's official press release confirmed the domain was used for log collection until July 2020, then hijacked. The incident is documented in technical security literature as a case study in "zombie" SaaS domain abuse, where expired service domains are re-registered by attackers to target legacy implementations.
