How to read this report

Safety Score evaluates observed signals. Evidence Confidence measures how complete, direct, fresh, and consistent those signals are.

No automated scan can guarantee that a website is safe.

Independent evidence brief

What we observed about j-wave.co.jp

Updated Oct 1, 2026

The latest scan examined 10 public pages on j-wave.co.jp. Website descriptions below come from the site itself. Registration, connection and threat findings were checked separately.

Purpose and visible content

On its About page, the site says: 東京のFMラジオ放送局 J-WAVEの会社情報

Registrar and domain history

A reliable creation date was not returned by the registration lookup. The report leaves domain age unverified rather than guessing.

Connection and hosting evidence

The checked homepage returned HTTP 200 in about 3000 ms.

A valid TLS certificate was observed, expiring Feb 15, 2027.

Threat checks and score context

External malware-provider coverage was unavailable. The report does not treat this missing check as a clean result.

Safety Score: 58/100. Evidence Confidence: 70%. These measure different things.

Server-side analysis

Automated security checks

Local antivirus and phishing checks

ClamAV · homepage HTMLLocal antivirus is not enabled
Phishing.Database · exact hostnameLocal feed snapshot unavailable

Sampled scripts and pages

Resource antivirus is not enabled

0 resources checked · 14 script links observed on the homepage. Partial resource coverage.

ClamAV inspects the fetched homepage HTML on our server. New scans also sample up to four linked scripts and two collected internal pages, with size and time limits. Scripts are not executed. Other downloads, private server files and logged-in pages remain outside this check. A signature match needs investigation and can be a false positive. No match is not a whole-site safety guarantee.

Exact hostname lookup uses a downloaded Phishing.Database snapshot. It does not send this domain to an external lookup API or mark sibling subdomains as harmful. Not listed does not mean safe. Snapshot age is download age, not proof that every entry was recently revalidated.

Homepage HTML only · Eight local rule families · local-security-v2

Checks use the fetched page and redirect chain. Scripts are not executed, forms are not submitted, and linked files are not downloaded. This is not a malware clearance.

Page resource inventory

Linked scripts14
Inline scripts9
Embedded frames1
External script hosts4

Counts describe the sampled HTML, not every resource loaded by the browser. External resources are common and are not automatically harmful.

No listed local patterns observed. The limited rule set cannot detect every threat or behavior.

External threat intelligence

Provider coverageNot checked

Local checks do not query external reputation databases. An unavailable check is never a clean result.

DNS observations · no external lookup API

Domain email protection

Exact-host SPF and DMARC observations help the owner investigate email impersonation risks. They are separate from website malware checks and do not change the Safety Score.

SPFPolicy record observed, not fully validated
DMARCMonitoring-only DMARC policy

What to do next

Review the records with your mail administrator. Inventory legitimate senders and test SPF and DKIM alignment before enforcing a stricter DMARC policy. Fix duplicate records and investigate overly permissive SPF rules.

This bounded check does not send email, probe SMTP, evaluate recursive SPF includes, verify DKIM signatures or apply organizational-domain DMARC inheritance. A missing subdomain record does not prove that no inherited protection exists. A DNS timeout is unknown, not an absent record. A policy record is not proof that messages authenticate successfully.

Responsible disclosure

security.txt

RFC 9116 observation

No readable security.txt file was observed at the standard locations. This is informational and is not evidence of malware.

Browser protections

Security headers

0 observed

Header evidence is unavailable. Missing data is not treated as a clean result or proof of compromise.

Response headers

Cookie protections

Passive observation

No Set-Cookie header was observed on the sampled homepage response. Other pages may set cookies separately.

Technologies

Google Tag Manager 96% jQuery 3.4.1 82%

Versions are shown only when publicly exposed by the page or response headers. An observed version is not, by itself, proof of a vulnerability.

JavaScript library advisories

JavaScript advisory analysis could not be completed or no eligible script files were sampled. No clean result is implied.

Recommended maintenance checks

jQueryConfirm the observed jQuery version is supported by your application and update it through your normal dependency process.

Questions about j-wave.co.jp

FAQ

Still have questions? Contact us →
Is j-wave.co.jp safe to visit?

The latest Safety Score is 58/100 with 70% Evidence Confidence. This is a point-in-time assessment of observed technical signals, not a guarantee. Check the exact address and avoid entering payment details if anything looks unusual.

Did the scan detect malware on j-wave.co.jp?

External threat-provider coverage was unavailable for this scan, so malware status is unverified.

When was j-wave.co.jp registered?

The registry lookup did not provide a reliable creation date in this scan.

Did j-wave.co.jp have a valid TLS certificate?

The scanner observed a valid TLS certificate using TLSv1.2. A valid certificate alone does not establish that the site is safe.

How does j-wave.co.jp describe itself?

The website's About page describes its purpose in the report above. This is publisher-supplied information and is separate from independent security findings.

Can a paid listing change this website's score?

No. Premium placement and owner-supplied pages are labelled separately. Technical evidence, the Safety Score and moderation decisions remain independent.
