What is this website?

Purpose and visible content
On its homepage, the site says: WWDC2016(Appleの開発者向け会議)が終わりました。昨年は、フリーランスエンジニアとして、友達と一緒に気楽にSFに遊びにいきましたが、今年は会社立ち上げ直後・絶賛プロダクト開発中ということもあり、朝食を食べながら、セッションビデオをApple TVにストリームしてキャッチアップしました。発表内容は盛り沢山でしたが、その中で気になったトピックをピックアップしてみました。なお、ちゃんと網羅的に内容把握されたい方は坂田さんのブログをどうぞ。CallKitの解放で、MNO離れとMVNO人気上昇がますます進むLINE、Whatsapp, ViberなどのVoIPアプリの無料電話で、着信に気付かず取れなかったという経験をした人は多いと思います。iOSではサードパーティのアプリが表示できる通知の作法が一律で決められており、電話の着信であろうとも、ロック画面にぴゅっと表示が出て、端末が一回震えるだけでした。これではなかなか気づかれないため、結局お店に電話するときや自宅に電話したりするときなどは普通の電話を使ってました。しかし今回のCallKitの解放により、LINE等のVoIPアプリでも標準の電話UIを利用すること

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 5000 ms.
A valid TLS certificate was observed, expiring Nov 20, 2026.
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: 59/100. Evidence Confidence: 70%. These measure different things.

Key findings
Report is current
The displayed evidence comes from the published immutable scan.
Confidence is separate
Unavailable evidence is shown as missing and never counted as clean.
Verify before sensitive actions

Fully explainable
Why this score?
Threat providers were unavailable. The neutral uncertainty baseline is not a clean verdict.
Evidence is unavailable.
Observed DNS records and network address were checked.
Observed certificate validity and TLS protocol were checked.
Observed security header values were checked for basic protective settings. Empty values, disabled HSTS and unrecognized values receive no credit. This is not a complete browser-policy validation.
Observed site metadata and About page were checked. Publisher-supplied details are not independently verified.
Popularity is weak context, not proof of safety. Unranked sites use a neutral baseline.
Observed HTTP status and final connection scheme were checked.
Server-side analysis
Automated security checks
Local antivirus and phishing checks
Sampled scripts and pages
Resource analysis incomplete
0 resources checked · 6 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
Counts describe the sampled HTML, not every resource loaded by the browser. External resources are common and are not automatically harmful.
Redirect from HTTPS to HTTPSecurity concern · 1
The observed redirect chain includes a downgrade to an unencrypted connection. Connection security is assessed separately.
External threat intelligence
Local checks do not query external reputation databases. An unavailable check is never a clean result.

DNS footprint
DNSKEY presence does not verify the DNSSEC signature chain. Missing records can mean no record was returned or the lookup was unavailable.

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.
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
No readable security.txt file was observed at the standard locations. This is informational and is not evidence of malware.
Browser protections
Security headers
Header evidence is unavailable. Missing data is not treated as a clean result or proof of compromise.
Response headers
Cookie protections
No Set-Cookie header was observed on the sampled homepage response. Other pages may set cookies separately.
Detected stack
Technologies
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
2 sampled JavaScript files checked locally with Retire.js. Database snapshot: 2026-11-01T02:40:08.730Z.
A version match is not proof that the website is infected or that an issue is exploitable here. Owners should review the advisory, check whether their code is affected and test an update. Up to four external script files are sampled, not every dependency, inline script or dynamically loaded resource.

Redirect chain
The chain is shown exactly as observed by the scanner. A redirect is not itself a malware finding, but unexpected domains or an HTTP downgrade deserve review.

Questions about yuichi.nu
FAQ
Is yuichi.nu safe to visit?
The latest Safety Score is 59/100 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 yuichi.nu?
External threat-provider coverage was unavailable for this scan, so malware status is unverified.
When was yuichi.nu registered?
The registry lookup did not provide a reliable creation date in this scan.
Did yuichi.nu have a valid TLS certificate?
The scanner observed a valid TLS certificate using TLSv1.3. A valid certificate alone does not establish that the site is safe.
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.
